Crayfish are important freshwater invertebrates both ecologically and economically. In Turkey, there is no aquaculture of this species, and it is solely produced through fishing. Owing to poor size selectivity of the fyke-nets used in harvesting this species, the rate of undersized catch is quite high (40.7%). This study aimed to enhance the size selectivity of fyke-nets through various manipulations.

This study investigated habitat use and movements of trout cod using radio-telemetry. Trout cod typically occupied small (<300 m) reaches of stream, undertook larger-scale movements and moved onto inundated riparian habitats during high flows. It occupied deeper water bank during the day and shallower water during the night and used areas with slower velocities more than was their availability. It also made extensive use of in-stream cover (i.e. wood). (Photograph by W. M. Koster.)

The InVEST water-yield model and support-vector regression (SVR) model were utilised to assess and forecast the ecosystem water-regulation value in Qinghai Area of Qilian Mountain National Park, China. The research showed that grassland plays a crucial role in regulating water, with an anticipated increase in both physical and monetary values by 2030. To further enhance monitoring efforts, it is recommended to establish an ecological big-data platform within the park.

Exploring what fish eat is important to understand how changes in the environment can affect their lives. In this study, we looked into the diet of an Amazonian catfish in a river affected by the construction of a dam. We found that the catfish mostly fed on sediment and aquatic insects, and these feeding habits were not strongly influenced by changes in the local water levels.

Lack of age data is a critical limitation in assessing the resource status of octopus. However, only a small number of researchers have the hands-on knowledge to execute these methods in the laboratory. Here, we present the first step-by-step guide to ageing octopus. We hope it will enable researchers new to ageing to undertake the process, as well as make an informed decision on the most suitable ageing method for their octopus species. (Photograph: E. D.

To explore climate effects on tiny aquatic life, we delved into how changes in water conditions affect Moina micrura, a small freshwater creature. Results showed that extreme pH harms the offspring and slows the heartbeat of this species, but warmth and longer daylight boost the numbers. Interestingly, M. micrura produces more males when food is scarce. This research informs strategies to protect these creatures in our tropical waters.

We investigated the immune responses in the respiratory tree of sea cucumber (Apostichopus japonicus) to high temperature, oil pollution, and the combined stress of high temperature and oil pollution. We found that acute exposure to oil pollution may have affect the immune function of sea cucumbers, whereas high temperature may exacerbate the health challenges of sea cucumbers subjected to environmental stress.

Currently, little information exists describing population structure of great hammerhead sharks (Sphyrna mokarran) in Australian waters. This study used genetic techniques to investigate structuring across the Indo-Pacific. No fine-scale population structuring was observed in Australia; however, structuring occurred for all Australian sharks when compared to those in the Red Sea. Findings suggest a single population for great hammerheads in Australia.

This perspective provides empirical data on the Ramsar Convention and gender equity. This paper assessed how Ramsar Convention complied with its own goals for gender mainstreaming in 2018, guided by the Global 2018 Gender and Wetlands Resolution agreed upon by 171 nations. The data were derived from National Reports from around the world. The findings shed light on the room for improvement in gender mainstreaming and gender equity in the wetland science and policy.

We calculated the social and economic contribution of the shark fishery operating in Western Australia, one of the world’s few sustainable shark fisheries. We found substantial management-driven reductions in fishing effort and improvement in catch rates. This fishery provides considerable socio-economic returns to regional economies, with an average annual market value of A$32.6 × 106.

Schizocypris altidorsalis is a freshwater fish only documented within a drying water reservoirs, on the border of Iran and Afghanistan. This study investigated the occurrence of highly host-specific monogenean parasites in this fish. A new species, Paradiplozoon jalalii, was found for the first time. Unless concerted efforts are initiated to restore their habitats, there is a significant risk of extinction for both species.

Water-column profiler data, collected from 2009 to 2018 along the North American continental shelf, are synthesised to provide near-bottom oceanographic baseline information about the area, and to help identify environmentally distinct biological regions. A modelling method is presented as an example for exploring relationships between environmental variables and demersal fishes over space and time in the study area.

The macrofauna associated with Halodule wrightii meadows had a positive relationship between taxonomic and functional diversities, increasing from the least to the most complex habitats. The most prominent differences were in the composition of functional characteristics. We attribute the high macrofaunal diversity to a high species turnover among and within meadows, which synergises with shifts in environmental factors (e.g. organic-matter content). Our results suggest that the loss of complexity in Brazilian seagrass meadows results in changes in community composition and the ecological functions performed by the organisms.

Striped marlin spawning in the central North Pacific was previously little studied. Our investigation has shown that both females and males mature at smaller sizes than in all other Pacific regions surveyed. These results have direct application for current efforts to evaluate the health and resilience of the population in the western and central North Pacific, which is currently considered to be commercially overfished and subject to continued overfishing.
