High clonality in Acropora palmata and Acropora cervicornis populations of Guadeloupe, French Lesser Antilles 
A. Japaud, C. Bouchon, J.-L. Manceau and C. Fauvelot

In Guadeloupe, the two endangered Acropora species are critically declining, like in the rest of Caribbean reefs. While examining the genetic status of two main remnant populations, we found an extremely high clonality in both species. This is alarming in the context of ongoing global warming as long periods of clonal growth without sexual recruitment may lead to the extinction of these populations.

Soft bodies make estimation hard: correlations among body dimensions and weights of multiple species of sea cucumbers 
James Prescott, Shijie Zhou and Andhika P. Prasetyo

Sound management of sea cucumber fisheries requires biological information including body measurements. We used hierarchical Bayesian errors-in-variables models to establish correlations among three types of weight measures and two body dimensions. The results can be applied to sea cucumbers in other areas and can be useful for data standardisation and size-based fisheries management.

Mobulid ray by-catch in longline fisheries in the south-western Atlantic Ocean 
F. Mas, R. Forselledo and A. Domingo

This paper presents the first by-catch assessment of mobulid rays in pelagic longline fisheries over the south-western Atlantic. At least two species were indentified and, although by-catch frequency was low, some uncertainties remained regarding their post-capture mortality. This work sheds light on mobulids’ interaction with longline fisheries, expands known distribution ranges, and raises concern about the potential effect of these fisheries on mobulid populations.

Artificial irrigation ponds and sea coast as foraging habitat for larids breeding in protected wetlands 
Esther Sebastián-González, Francisco Botella, Otso Ovaskainen, Antonio Delgado and José Antonio Sánchez-Zapata

Questions related to the preservation of foraging sites of breeding birds have received little attention, although they can be of major importance for population persistence. Here, we used stable isotopes and field observations to evaluate the relative importance of man-made irrigation ponds as foraging areas for a larid community of conservation concern. Our study showed that larids breeding in mixed colonies segregate spatially in their foraging niche between marine and freshwater environments. Both breeding and foraging habitats need to be addressed when analysing larid population dynamics and conservation strategies.

Patterns of connectivity and population structure of the southern calamary Sepioteuthis australis in southern Australia 
Timothy M. Smith, Corey P. Green and Craig D. H. Sherman

Southern calamary are an important fisheries species and understanding levels of connectivity across their distribution is important for management purposes. Genetic discrimination techniques suggested that there is a high level of gene flow and connectivity throughout their distribution. Such results indicate the southern calamary population has the potential to maintain a level of resilience to altering conditions if large scale mixing is maintained.

Year-round maturity of the chaetognath Aidanosagitta regularis in the Hauraki Gulf, New Zealand 
Wesley H. Webb and Mary A. Sewell

The reproductive biology of planktonic chaetognaths is poorly known, particularly with regard to the importance of seasonal factors. We undertook a year of semilunar plankton sampling in the Hauraki Gulf, New Zealand, to survey sexual maturity of Aidanosagitta regularis; surprisingly, breeding of A. regularis appeared unconstrained by seasonal factors, as reproductively mature individuals were available year-round. This has implications for embryological study of the chaetognaths.

Lake Eyre golden perch (Macquaria sp.) spawning and recruitment is enhanced by flow events in the hydrologically variable rivers of Lake Eyre Basin, Australia 
B. J. Cockayne, D. Sternberg, D. W. Schmarr, A. W. Duguid and R. Mathwin

Understanding the links between fish recruitment and riverine flows is integral for setting priorities for river-management strategies. We found that within-channel flow events soon after months of no-flow were important spawning triggers for the endemic Lake Eyre golden perch (Macquaria sp.). Subsequent fish recruitment was also strongly associated with the number of flow-events per year. These results highlight the importance of maintaining the naturally variable flow regime of Australia’s arid- and semi-arid zone rivers.

Behavioural responses to simulated bird attacks in marine three-spined sticklebacks after exposure to high CO2 levels 
Joacim Näslund, Erik Lindström, Floriana Lai and Fredrik Jutfelt

Ocean acidification (OA), caused by increased levels of carbon dioxide (CO2) in the sea water, has previously been reported to affect the behaviour of fishes. Here, we find that some behaviours (lateralisation and freezing) were affected by OA in three-spined sticklebacks, but the general response to a bird predator (spatial avoidance) was not affected. Thus, the general avoidance behaviour appears to be robust to elevated CO2 levels, despite some behaviours being altered.

Activity, substrate selection, and effect of a simulated Amazon flood regime on the behaviour of the apple snail, Pomacea bridgesii 
Timoteo Tadashi Watanabe, Gustavo Yomar Hattori and Bruno Sampaio Sant'Anna

The present study investigated the behaviour of the apple snail Pomacea bridgesii on a simulated flood-pulse water regime. The results show that there are differences between day and night behaviours (activity and substrate selection). There were also differences between behaviours in dry and maximum water-level periods. Therefore, the floodplain regime influences the activity of P. brigesii displaying adaptations to minimise water loss.

Temperature, length of growth season and phytoplankton abundance in the Gulf of Maine 
Knut Seip

Does global warming of the sea surface decrease or increase phytoplankton abundance? This paper shows that, although within-season phytoplankton abundance decreases with increasing water temperature, annual average phytoplankton abundance increases with average water temperature, likely because an increase of 1°C lengthens the growth season by ~20 days. However, it is not known if higher annual average phytoplankton abundance translates into larger stocks of zooplankton and fish.

The influence of water quality on hyporheic invertebrate communities in agricultural catchments 
Samuel Kibichii, Hugh B. Feeley, Jan-Robert Baars and Mary Kelly-Quinn

Understanding the role of agriculture in water quality and river health is vital. This study investigated the effect of agricultural run-off on the chemical and biological status of the hyporheic zone, and indicates that hyporheic zones are degraded in intensely farmed catchments. These findings emphasise the importance of holistic catchment management in the protection and sustainability of freshwater systems.

Oithona nana and O. helgolandica population dynamics and the influence of physical and trophic factors were studied at an estuarine system. O. nana proliferates near river runoff, mainly because a retention mechanism and a potential ecological advantage of this species denoted in body size and egg number and size. O. helgolandica populations did not increase in this system.

Breeding habitat selection in an obligate beach bird: a test of the food resource hypothesis 
Anna Cuttriss, Grainne S. Maguire, Glenn Ehmke and Michael A. Weston

One beach is not the same as another as far as a beach nesting-bird, the Hooded Plover, is concerned. They breed in sites with more invertebrate prey, and which have different assemblages of prey species, compared with sites where they do not breed. Thus, beaches apparently vary in terms of their ability to support this threatened bird species.

Maite Vázquez-Luis, Joseph A. Borg, Carlos Morell, Gàlia Banach-Esteve and Salud Deudero

The effect of boat anchoring on the Mediterranean endemic bivalve Pinna nobilis was assessed experimentally in the field by deploying non-biological mimic units. Boat anchoring influence was three times higher in affected than in control areas, having also an adverse effect on Posidonia oceanica meadows. Moreover, lower values of natural P. nobilis density and size classes were recorded from the affected areas.

Community structure of reef fishes on a remote oceanic island (St Peter and St Paul’s Archipelago, equatorial Atlantic): the relative influence of abiotic and biotic variables 
Osmar J. Luiz, Thiago C. Mendes, Diego R. Barneche, Carlos G. W. Ferreira, Ramon Noguchi, Roberto C. Villaça, Carlos A. Rangel, João L. Gasparini and Carlos E. L. Ferreira

Reef-fish communities on large coral-reef systems are incredible complex; in contrast, isolated oceanic islands represent an opportunity to understand processes on ecologically simpler ecosystems. This study investigated the reef-fish community of the world’s smallest tropical oceanic island and found that environmental drivers, especially depth, are more important than biotic interactions in its organisation, probably because of low species-richness. The low-species richness translates in low functional redundancy, indicating that remote islands may be more vulnerable to human impacts than interconnected reef systems.

Biomonitoring of the environmental contamination by organotins in the Gulf of Tunis: occurrence of imposex in Stramonita haemastoma (Linnaeus, 1767) 
Wafa Boulajfene, Jihen Boukhicha, Alan Deidun, Daniela Berto, Teresa Romeo, Oum Kalthoum Ben Hassine and Sabiha Tlig-Zouari

Imposex is mainly caused by organotins’ accumulation in gastropods tissues. This research aimed to study the imposex in of Stramonita haemastoma individuals collected along the rocky coastline of the Gulf of Tunis. Sexual modifications occurred to different degrees in all stations essentially close to harbours. An inverse relationship between the distances from harbours and the occurrence of imposex was observed.

Important sources of variation to be considered when using fin clips as a surrogate for muscle in trophic studies using stable isotopes 
David E. Galván, Manuela Funes, Ana L. Liberoff, Florencia Botto and Oscar O. Iribarne

Sampling muscle is the prevalent technique for stable isotope analysis in fish and typically involves the death of the individuals. Fin-clipping is a non-lethal, easy-to-implement sampling technique that preserves fish welfare. This study assessed the suitability of caudal fin as a replacement for muscle in trophic studies. Results support the use of caudal fin as a surrogate for muscle but also showed that fin-muscle relationship varies among species and it is affected by fish size.

Mesozooplankton community in a seasonally hypoxic and highly eutrophic bay 
Min-Chul Jang, Kyoungsoon Shin, Pung-Guk Jang, Woo-Jin Lee and Keun-Hyung Choi

Low summer oxygen in a highly eutrophic and seasonally hypoxic coastal bay was attributed to high phytoplankton stocks, together with high temperature and stratification of the water column. A distinct mesozooplankton community was identified in summer of large freshwater discharge. The abundance of a marine cladoceran was positively related to oxygen levels, suggesting that hypoxic conditions may have lethal or sublethal effects.

We quantified and identified the allochthonous leaf litter entering a headwater Atlantic Rain Forest stream throughout 1 year. We found that most organic matter entered the stream by a lateral input pathway, driven mainly by precipitation, as well as by changes to the leaf litter input of tree species throughout the year.

Water level decrease and increased water stability promotes phytoplankton growth in a mesotrophic subtropical lake 
Eduardo V. Fuentes and Mauricio M. Petrucio

Understanding the mechanisms that favour increase in phytoplankton biomass and bloom formation in freshwater ecosystems is a major challenge for managers and researchers, especially in environments dominated by cyanobacteria. Based on 5 years of observation, our study evaluated the importance of climatic factors in determining environmental conditions such as water level and mixing regime in a subtropical lake used for public water supply. The results show the importance of daily stratifications events for the accumulation of phytoplankton biomass.

Evidence for a broad-scale decline in giant Australian cuttlefish (Sepia apama) abundance from non-targeted survey data 
Thomas A. A. Prowse, Bronwyn M. Gillanders, Barry W. Brook, Anthony J. Fowler, Karina C. Hall, Michael A. Steer, Camille Mellin, N. Clisby, Jason E. Tanner, Tim M. Ward and Damien A. Fordham

The breeding aggregation of the giant Australian cuttlefish (Sepia apama) in northern Spencer Gulf, Southern Australia, has declined dramatically since the turn of the century. Our analysis of long-term by-catch and harvest records for the population indicated that this trend was not due to the failure of the species to aggregate, nor due to the aggregation occurring elsewhere, but was part of a systemic decline in the abundance of the population over this period. We evaluated a suite of potential climatic and harvest-related stressors for this species but could not attribute this decline in abundance to specific causes.

Re-evaluation of the diversity and distribution of diazotrophs in the South China Sea by pyrosequencing the nifH gene 
Peng Xiao, Yongguang Jiang, Yang Liu, Wenhua Tan, Wenhua Li and Renhui Li

In this study, pyrosequencing was used to investigate the diversity and composition of putative diazotrophs in the South China Sea. The result showed that Trichodesmium and γ-proteobacteria were the two dominant species among the putative N2-fixing microorganism community. The predominance of the two genotypes in the South China Sea contributed to low diversity of putative diazotrophs.

Attached bacteria can play a major role in carbon and nutrient cycling but their importance differs among habitats. We investigated the dynamics of attached and free-living bacteria in the coastal waters of Malaysia, and found that attached bacteria formed a larger fraction of total bacteria in eutrophic relative to oligotrophic waters, and showed a preference for chlorophyll-a based particles.

Laboratory feeding-preference experiments showed that the estuarine crab Sesarma catenata preferred decomposed leaves of terrestrial riparian trees, followed by decomposed and mature leaves of the marshgrass Spartina maritima. The relative low carbon : nitrogen ratios of S. maritima and high bacterial production associated with decomposed terrestrial leaves may explain the trophic behaviour of S. catenata.

Dissolved organic carbon characteristics in an acidified groundwater-dependent ecosystem 
Azra Mat Daud, Suzanne McDonald and Carolyn E. Oldham

Dissolved organic carbon (DOC) plays an important role in groundwater-dependent wetlands, through its ability to mediate microbial processes and therefore the fate of pollutants. This work explores the effect of acidity on the structure of DOC, which in turn affects its reactivity. We have shown that the DOC structure is highly variable in both space and time, and dependent on local hydrology.

Effects of benthic substrate, nutrient enrichment and predatory fish on freshwater crayfish (kōura, Paranephrops planifrons) population characteristics in seven Te Arawa (Rotorua) lakes, North Island, New Zealand 
I. A. Kusabs, J. M. Quinn and D. P. Hamilton

Populations of kōura, or freshwater crayfish (Paranephrops planifrons), were quantified along a eutrophication gradient in seven Te Arawa lakes using the tau kōura, a traditional Māori harvesting method. Our results suggest that benthic substrate is more important in determining kōura population abundance than nutrient enrichment (using chlorophyll-a as a proxy) or predatory fish (rainbow trout abundance). Lake trophic status in conjunction with lake morphology appeared to indirectly affect kōura distribution in the sheltered, steep sided lakes, through hypolimnetic deoxygenation.

Development of habitat prediction models to reduce by-catch of sailfish (Istiophorus platypterus) within the purse-seine fishery in the eastern Pacific Ocean 
Raul O. Martinez-Rincon, Sofia Ortega-Garcia, Juan G. Vaca-Rodriguez and Shane P. Griffiths

By-catch has been considered as a main issue that may compromise suitability in marine ecosystems. In this work we propose a habitat prediction model approach to mitigate by-catch of sailfish based on spatial and environmental. Our results show that this approach may be considered as an additional fisheries management tool that may be used to support temporary spatial-temporal closure to reduce sailfish by-catch.

Does the telemetry technology matter? Comparing estimates of aquatic animal space-use generated from GPS-based and passive acoustic tracking 
Ross G. Dwyer, Hamish A. Campbell, Terri R. Irwin and Craig E. Franklin

Underwater passive acoustic telemetry and satellite telemetry are key technologies for observing aquatic animal movements. Using a dual-tagging approach, we show that estimates of travel distance, home range and the conclusions reached can vary according to the technology by which these data were obtained. This study provides recommendations and methodologies whereby telemetry technology biases may be quantified and minimised.

The declining cover of stony corals on tropical reefs is at the centre of the coral reef crisis, and while much is known about the factors killing corals, little is known about the factors determining their ability to replace themselves. In this paper we exploit four well-studied coral reef locations in the Caribbean and Pacific to evaluate the role of long-term variation in coral recruitment and the success of young corals in driving changes in coral cover. Our results reveal dramatic differences among locations in the capacity of corals to replace themselves through sexual reproduction (i.e. post-settlement success), with these effects probably playing an important role in determining the rate at which coral cover is lost (or gained) on present-day reefs.

Land use structures fish assemblages in reservoirs of the Tennessee River 
L. E. Miranda, J. M. Bies and D. A. Hann

Inputs of nutrients, sediments and detritus from catchments can promote selected components of reservoir fish assemblages, while hindering others. We compared fish assemblages in reservoirs of two sub-basins of the Tennessee River representing differing intensities of agricultural development, and hypothesised that fish assemblage structure indicated by species percentage composition would differ among reservoirs in the two sub-basins. We observed a shift from an invertivore-based fish assemblage in forested catchments to a detritivore-based fish assemblage in agricultural catchments that may be a widespread pattern among reservoirs and other aquatic ecosystems.

Jerom R. Stocks, Charles A. Gray and Matthew D. Taylor

Characterising the movement and habitat affinities of fish is a fundamental component in understanding the functioning of marine ecosystems. Acoustic telemetry was employed at two coastal temperate rocky-reefs in south-east Australia to examine the movements, spatial utilisation and residency of the herbivorous teleost Girella elevata. Spatial metrics of habitat use highlighted the susceptibility of G. elevata to recreational fishing pressure. Such studies are providing important data for spatial management measures such as marine protected areas and increasing our understanding of the latitudinal interactions of fish populations.

Age and size compositions, habitats, growth and reproductive characteristics of a terapontid (Pelates octolineatus) in coastal waters 
Lauren Veale, Peter Coulson, Norman Hall, Alex Hesp and Ian C. Potter

On the lower Western Australian coast, the terapontid Pelates octolineatus uses seagrass as a nursery area during the first year of life, and then moves out into sparser seagrass in deeper waters, where it matures at the end of its second year of life at total lengths (TL) of 140–170 mm. This species attained a maximum TL of ~256 mm and maximum age of 10 years. A sine-based growth curve emphasised that growth is seasonal and instantaneous growth rates were shown to peak in the warm summer months and to decline in amplitude with age. Gonadal recrudescence occurs in early spring as water temperature and day length increases and spawning peaks in late-spring to mid-summer when water temperatures are approaching their maxima.

Repairing Australia's estuaries for improved fisheries production – what benefits, at what cost? 
Colin Creighton, Paul I. Boon, Justin D. Brookes and Marcus Sheaves

With Australia's narrow continental shelf, Australia's estuaries, embayments and coastal waters are essential to fisheries productivity and marine biodiversity. Yet these are our most degraded ecosystems. This Business Case demonstrates that an investment in repair of $350 million would be repaid just from increased value of commercial fish catch in less than 5 years – probably a far greater return on investment than any of Australia's previous environmental initiatives.

Movement patterns and habitat use of juvenile mangrove whiprays (Himantura granulata) 
Lauren E. Davy, Colin A. Simpfendorfer and Michelle R. Heupel

Understanding the movements and space use of animals is necessary to identify vital habitats and better manage vulnerable species. We used acoustic telemetry to examine movement patterns of juvenile Himantura granulata in an intertidal bay. The majority of rays remained within the intertidal bay for the entire monitoring period, demonstrating the importance of intertidal habitats to H. granulata. Rays exhibited refuging behaviour in mangrove and reef habitats, suggesting that predation risk may be a principal factor influencing the movement of small rays.

The decline of seagrass beds has been accelerated by opportunistic macroalgae blooms. The feeding behaviour of mudsnail Peringia ulvae was studied with the aim of assessing its potential role in preventing the occurrence of macroalgal blooms. Snails grazed on all opportunistic macroalgae tested; however, sediment was the feeding niche preferred. Therefore, the hypothesis that P. ulvae has a role in preventing macroalgal blooms was not supported.

pH-dependent toxicity of serotonin selective reuptake inhibitors in taxonomically diverse freshwater invertebrate species 
Rumya Sundaram, Bradley W. Smith and Thomas M. Clark

The toxicity of three antidepressants in diverse freshwater species was positively correlated with ambient pH, and varied among drugs and taxa. The environmental impact of these pollutants thus becomes greater as pH increases, and is greater in habitats containing sensitive species. The results suggest that sublethal effects will also be influenced by ambient pH, and other psychotropic amine drugs will behave in a similar way.

We used mtDNA sequences to study the population genetic structure in the stream dwelling caddisfly Rhyacophila minor. We detected significant genetic subdivision across a spatial scale of only 45 km, and a phylogeographic break that corresponded with the characteristics of bedrock and surficial geology. This study demonstrates the roles that limited gene flow and genetic drift have in driving population differentiation at small spatial scales.

Fishery-independent surveys were undertaken to investigate shark communities along ~400 km of the tropical eastern coast of Australia. Multivariate analyses identified significant spatial heterogeneity in immature-shark communities. Results demonstrated that data on nursery function from restricted areas may not accurately portray patterns occurring over broader geographic scales, and this diversity may provide population-level benefits for sharks.

Victoria S. Milner, Nigel J. Willby, David J. Gilvear and Charles Perfect

In minimally disturbed river systems, identifying the influence of physical habitat on biological structure is important if the effects of alterations to physical habitat are to be understood. This study determined whether four channel types in an existing process-based geomorphic typology had distinct physical habitat and macroinvertebrate community composition. The findings reveal geomorphic typing of rivers can provide an initial assessment of ecological status and physical habitat conditions.

Age and growth of sharptooth catfish, Clarias gariepinus (Burchell, 1822) (Clariidae), in the Lower Okavango Delta, Botswana 
Thethela Bokhutlo, Olaf L. F. Weyl, Ketlhatlogile Mosepele and G. Glenn Wilson

Managing any inland fishery requires reliable age data and accurate estimates of growth rate. We used otolith-derived age estimates to compare patterns of age and growth for Clarias gariepinus from the Lower Okavango Delta in northern Botswana to those from the Upper Delta and found that two distinct populations of C. gariepinus may exist between the two regions. The fairly short life span and high variability in growth of C. gariepinus in the Lower Okavango Delta are important indicators that it is imperative to maintain natural habitat and flow regime for sustainable management of fishery resources in flood pulsed ecosystems.

Atypical correlation of otolith strontium : calcium and barium : calcium across a marine–freshwater life history transition of a diadromous fish 
Paul Hamer, Angela Henderson, Michael Hutchison, Jodie Kemp, Corey Green and Pierre Feutry

Inferring fish movements between marine and freshwater from otolith chemistry generally assumes that the strontium : calcium ratio is positively related to salinity and the barium : calcium ratio negatively related. This study of jungle perch (Kuhlia rupestris) provides an example where both otolith strontium : calcium and barium : calcium increased upon transition from marine to freshwater. While this atypical result driven by variation in ambient calcium challenges the above assumption, variation in the otolith element : calcium ratios remained consistent with variation in the ambient ratios.

The influence of an offshore artificial reef on the abundance of fish in the surrounding pelagic environment 
Molly E. Scott, James A. Smith, Michael B. Lowry, Matthew D. Taylor and Iain M. Suthers

Underwater video was used to observe the fish assemblage surrounding an offshore artificial reef, in Sydney, Australia. We found up to 10 times more fish on the reef itself than at 30, 100 and 500 m from the reef. This suggests that artificial reefs are very effective at increasing fish abundance, but generally act on a localised scale (<30 m).

Age and growth of the white shark, Carcharodon carcharias, in the western North Atlantic Ocean 
Lisa J. Natanson and Gregory B. Skomal

Accurate age estimates are essential for the sustainable management and conservation of all fish populations, including sharks. In this study, we use vertebral band counts coupled with bomb carbon validation to estimate the age and growth of white sharks in the western North Atlantic. Our findings indicate that this species grows significantly slower and lives considerably longer than previously thought.

Plant litter diversity affects invertebrate shredder activity and the quality of fine particulate organic matter in streams 
Isabel Fernandes, Sofia Duarte, Fernanda Cássio and Cláudia Pascoal

We tested how loss of litter diversity and time after loss of diversity affect leaf breakdown by invertebrate shredders. Changes in plant litter diversity affected shredders activity (leaf consumption and FPOM production), and the quality of food resources (FPOM and shredders) to higher trophic levels in streams; such effects are likely to become stronger with time after loss of diversity.

From perennial to temporary streams: an extreme drought as a driving force of freshwater communities 
Carmen L. Elias, Ana Raquel Calapez, Salomé F. P. Almeida and Maria João Feio

Changes in trait proportions were used to assess the effects of an uncommon drought event in diatom and macroinvertebrate communities in Atlantic-temperate perennial streams. The trait proportions of these temperate communities were also compared with those from temporary Mediterranean streams. This study suggests that the effects of drying were long-lasting for macroinvertebrates. However, only the diatom shifted towards proportions occurring in Mediterranean streams.

Shark and ray life history 
blank image
Colin A. Simpfendorfer and Bradley Wetherbee
pp. i-ii

As many of the world’s shark and ray populations continue to decline there is a growing need for improved conservation and management. One of the key requirements enabling design of effective conservation and management actions is life history parameters as these provide basic information on the dynamics of populations. Life history parameters (e.g. age, growth and reproduction) are directly tied to the reproductive output of a species, and thus unequivocally linked to the capacity of a population to withstand exploitation and to recover from decline. Despite this importance, research on the life history of sharks and rays has declined in recent years as ‘cooler’ and non-lethal topics have become more commonplace. However, on-going research on life history is fundamental for positive action to address declines of shark populations and policies aimed at recovery of populations. To highlight research that has been and is being conducted on the life history of sharks and rays, we have compiled a ‘Shark and ray life history’ virtual issue of Marine and Freshwater Research, which is freely available from the Journal’s website for a limited time.

Nicole Flint , Michael R. Crossland and Richard G. Pearson
pp. 293-304

Relationships between fluctuating hypoxia and sublethal effects on ventilation, feeding and growth of juvenile barramundi, eastern rainbowfish and sooty grunter were investigated in laboratory experiments. Fish were found to be tolerant of fluctuating hypoxia, as they continued to feed and grow under daily exposure to severe treatments for several weeks, although some negative effects were recorded.

pp. 305-316

Advances in research and technology over the last 20 years have improved the precision and utility of bomb radiocarbon dating in validating the age and growth of fishes. The large and iconic reef fishes chosen for this age validation study exemplifies the current state of the technique by pushing the limits of sample extraction and analysis. Bomb radiocarbon dating can now provide valid estimates of age for fishes that could not be considered previously because of otolith mass limitations.

pp. 317-328

The effects of sediment resuspension, salinity and temperature on plankton communities of tidally influenced coastal lakes were investigated using feeding experiments and a monitoring study. Moderate levels of turbidity and salinity affected clearance and ingestion rates of Daphnia carinata, heterotrophic nanoflagellates (HNF) and ciliates in the experiments. The monitoring study showed that resuspension, salinity and temperature affect a wide variety of biota.

pp. 329-342

The reproductive cycle of Arbacia dufresnii was studied in two contrasting populations in Patagonia, Argentina. A. dufresnii showed an annual cycle, with gametogenesis occurring mainly in the autumn and the winter. An extended spawning period occurs during the spring and the summer. Temporal and spatial differences in gonadal cell composition were detected suggesting plasticity in reproductive traits.

Composition and health of fish in refugia habitat of ephemeral tributaries to the lower Zambezi in southern Africa 
blank image
Ayron M. Strauch , Alana R. Kapust and Christine C. Jost
pp. 343-351

Many rivers stop flowing in seasonally dry regions and freshwater communities become dependent on resulting pools of water for survival. We examined the relationship between pool habitat quality and indices of fish health; finding that certain measures were positively correlated with water quality but that results depended upon fish type. Understanding the affect of changing habitat on ecosystem health is important for rural development.

pp. 352-359

Coastal systems are prone to strong salinity fluctuations over time. Using long-term data (6 years), this study demonstrated that temporally structured environmental variables (salinity and total phosphorus) were important for zooplankton composition, and that the resting egg bank likely plays a minor role in zooplankton colonisation during low-salinity periods.

T. J. Brinkman and A. M. Smith
pp. 360-370

White Island, north-east New Zealand, is an active volcano, bubbling warm gas into shallow seawater. We measured water and calcified algae near and far from the volcano, and discovered that these vents make seawater both warmer and more acid than the surrounding ocean, thus affecting the strength of skeletons living there. White Island offers a natural laboratory for investigating the effects of future climate on marine organisms and environments.

Allen M. Aven , Ruth H. Carmichael , Matthew J. Ajemian and Sean P. Powers
pp. 371-374

For satellite-tracked manatees, loss of fine-scale movement data because of satellite tag detachment or functionality problems is common. We supplemented manatee satellite-tracking data by using moored datalogging hydrophones deployed at strategic locations throughout our study area to detect the belt acoustic transmitters that were retained even when satellite tags were lost. Using this approach, we detected five tracked manatees, including three that had lost satellite tags, and concurrently detected other estuarine fauna tagged by local researchers using compatible equipment. The use of moored datalogging hydrophones partially mitigated the loss of satellite-tracking data and enhanced collaborative opportunities with other researchers.

pp. 375-380

Jungle perch (Kuhlia rupestris) are in decline. Current captive breeding practice involves multiple individuals per tank. We first determined the minimum number of microsatellite loci and larvae required to accurately quantify parental contributions. Not all fish contributed to larval production with a skew towards offspring from one mating pair (average 62%). This has implications for restocking of this species.

pp. 381-384

Cymothoid isopods include mouth-dwelling fish parasites that can pose threats to fisheries and aquaculture. Here we describe a significant correlation between host size and that of both female and male Ceratothoa italica infecting the striped sea bream Lithognathus mormyrus. We discuss anatomical and behavioural constraints that may explain this association and could represent a framework to understand the adaptive radiation of this family of parasites.
