MF25053Advancing fish early life-history research: daily age determination of walleye pollock (Gadus chalcogrammus) with Fourier transform–near-infrared spectroscopy

Esther D. Goldstein 0000-0002-0499-7288, Mary E. Matta, Charles D. Waters 0000-0003-4606-3202, Heather K. Fulton-Bennett 0000-0002-5938-9714, Brenna C. Hsieh, Craig R. Kastelle 0000-0002-6681-1602, Johanna J. Vollenweider, Jakub T. Sliwinski and Thomas E. Helser

Fish daily age information provides insight into growth, phenology, recruitment and survival, but is rarely incorporated into fisheries management because data collection is laborious. We tested Fourier transform–near-infrared (FT-NIR) spectroscopy as a rapid method to determine daily age from otoliths of an important commercial species, walleye pollock (Gadus chalcogrammus). Results indicated that FT-NIR spectroscopy may provide a valuable tool to collect daily age information for research and management.

MF24180Reconciling blue spaces: evaluating social equity and justice in state-led Indigenous marine development programs

The Blue Peacebuilding Scorecard introduces an innovative method for assessing how governments are integrating Indigenous rights and interests into ocean management. This research debuts the BPS with case studies from Australia, Canada and New Zealand. The authors spotlight programs that other nations can learn from to reduce conflict, advance reconciliation and work towards a sustainable ocean future.

There is widespread contamination of our oceans with plastic waste, dominated by MPs and NPs. Crustaceans, such as shrimp, exhibit omnivorous feeding habits, consuming all available substances in their environment, including MPs from water, sediment and prey. The detrimental effects of MPs and NPs on crustaceans are multifaceted, encompassing metabolic and biochemical disturbances, alterations in feeding behaviours, histological anomalies, organ dysfunctions, synergistic interactions with heavy metals, reproductive malformations, dysregulated pattern of gene expression, elevated oxidative stress responses and diminished survival rates.

MF24250Characteristics of a marine wildlife tourism site: Stingray City, Cayman Islands, before, during and after the COVID-19 global pandemic

Bradley M. Wetherbee 0000-0002-3753-8950, Colby D. Kresge, Jeremy J. Vaudo 0000-0002-6826-3822, Guy C. M. Harvey, Jessica C. Harvey and Mahmood S. Shivji

Stingray City, Cayman Islands, is one of the most famous marine life interaction sites in the world, where an aggregation of stingrays are regularly fed by and interact with humans. During the COVID-19 pandemic, feeding of stingrays ceased and tourism operations at the site shut down. During this time, the size and composition of the stingray aggregation changed dramatically and even following resumption of tourism activities, the aggregation remained altered from pre-pandemic conditions. This study has illustrated the large-scale effects that human activities may have on wildlife tourism.
