Marine mammal recovery is associated with the resurgence of a nematode parasite. [PDF]

Ecology
Abstract As the oceans change, the abundance of parasites and the risk of infection to marine mammals may also be changing. Nematodes in the family Anisakidae can harm marine mammals, and recent studies have revealed a global increase in these parasites, but the cause is unknown.

Assessment of heavy metal concentrations in imported marine fish species consumed in Ogun state, Nigeria [PDF]

Aceh Journal of Animal Science
Fish is an affordable protein source in developing countries such as Nigeria, however, human activities like mining, agriculture, and industrial discharges negatively impact these aquatic resources and their environment. Heavy metals leach into the ocean

The Potential Sex Determination Genes, Sox9a and Cyp19a, in Walleye Pollock (Gadus Chalcogrammus) Are Influenced by Water Temperature [PDF]

Journal of Marine Science and Engineering, 2020
Our aim was to study the relationship between the sex-determining genes, sox9a and cyp19a, and water temperature in Gadus chalcogrammus. We assessed the sex ratio based on the expression levels of sox9a and cyp19a at different water temperatures (5, 8 ...

Type-I-hypersensitivity to 15 kDa, 28 kDa and 54 kDa proteins in vitellogenin specific to Gadus chalcogrammus roe

Allergology International, 2020
Background: Fish roe allergy is a common health problem in countries where sea food is a major part of the diet, such as Japan. β′-component (β′-c) in fish roe has been identified as a major antigen for patients who show hypersensitivity to various fish ...

Shifting stage‐specific constraints on productivity shape recovery potential for Yukon River Chinook salmon [PDF]

Ecol Appl
Abstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

Biological and environmental covariates of juvenile sockeye salmon distribution and abundance in the southeastern Bering Sea, 2002–2018 [PDF]

Ecology and Evolution
Climate change is altering the distribution and abundance of marine species, especially in Arctic and sub‐Arctic regions. In the eastern Bering Sea, home of the world's largest run of sockeye salmon (Oncorhynchus nerka), juvenile sockeye salmon abundance

Characterization of rheological and physicochemical properties of Alaska walleye pollock (Gadus chalcogrammus) roe. [PDF]

J Food Sci Technol, 2018
Alaska walleye pollock (Gadus chalcogrammus) roe is a commercial product of the Alaska pollock fishery. Accordingly, the objective of this study was to determine functional properties of pollock roe through rheological and physicochemical analyses. Pollock roe rheological properties were determined by flow sweep and frequency sweep measurements.
