Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

open access: yesEthology, EarlyView.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also

Fisheries Trade and Blue Nutrient Flows in Pacific Island Countries

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Pacific Island Countries (PICs) are located in highly productive fishing regions that supply nutrient‐rich fish to global markets. Marine fisheries are a critical source of protein and essential micronutrients for billions of people worldwide, supporting both local diets and global food security.

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to
