Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

Investigating the Dynamics of Sex‐Structured Stock Assessment Models Under Sexual Size Dimorphism

Fisheries Management and Ecology, EarlyView.
ABSTRACT The integration of separate sexes in stock assessment models represents an advancement towards more realistic modeling of interactions between fisheries and target species. However, increased model complexity can also introduce additional uncertainty into the modeling process.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous
