Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems
Fisheries Oceanography, EarlyView.ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Journal of Fish Biology, EarlyView.Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Journal of Fish Biology, EarlyView.Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response
Journal of Fish Biology, EarlyView.Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Presence of 6PPD-quinone in runoff water samples from Norway using a new LC–MS/MS method
Frontiers in Environmental Chemistry, 2023 The chemical 6PPD-quinone is highly toxic to some fish species of the Oncorhynchus and Salvelinus genera and is the oxidation product of the common car tire additive 6PPD.

Characterization of hepatic glutathione S-transferases in coho salmon (Oncorhynchus kisutch) [PDF]
Aquatic Toxicology, 2007 The glutathione S-transferases (GSTs) are a family of phase II detoxification enzymes which protect against chemical injury. In contrast to mammals, GST expression in fish has not been extensively characterized, especially in the context of detoxifying waterborne pollutants.
