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

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

Using Vessel Monitoring System Data to Identify and Characterize Trips Made by Fishing Vessels in the United States North Pacific.

PLoS ONE, 2016
Time spent fishing is the effort metric often studied in fisheries but it may under-represent the effort actually expended by fishers. Entire fishing trips, from the time vessels leave port until they return, may prove more useful for examining trends in

Fluid preservation causes minimal reduction of parasite detectability in fish specimens: A new approach for reconstructing parasite communities of the past?

Ecology and Evolution, 2020
Long‐term datasets are needed to evaluate temporal patterns in wildlife disease burdens, but historical data on parasite abundance are extremely rare. For more than a century, natural history collections have been accumulating fluid‐preserved specimens ...

Concentrations and Risk Assessment of Heavy Metals in Tissues of Walleye Pollock (Gadus chalcogrammus) Captured from the Northeastern Coast of Korea

Journal of Food Protection, 2019
All heavy metals, except Hg, were well accumulated in liver compared with muscle and gonads. Estimated daily intakes of heavy metals were within 2% of the provisional maximum tolerable daily intakes, Hazard quotients of heavy metals were less than 1.0. Appropriate intake control of G. chalcogrammus is necessary to protect human health in the future.

Impacts of temperature and food availability on the condition of larval Arctic cod (Boreogadus saida) and walleye pollock (Gadus chalcogrammus)

, 2018
The Arctic marine environment is rapidly changing with rising sea surface temperatures, declining sea ice habitat and projected increases in boreal species invasions.

A depth model for informing Chinook salmon bycatch risk in the Gulf of Alaska

Animal Biotelemetry
Background Bycatch of Chinook salmon (Oncorhynchus tshawytscha) in the Gulf of Alaska walleye pollock (Gadus chalcogrammus) fishery poses both conservation and management challenges. While fleet communication and excluder devices have improved mitigation

Effects of temperature and food availability on the survival and growth of larval Arctic cod (Boreogadus saida) and walleye pollock (Gadus chalcogrammus)

, 2018
Arctic cod (Boreogadus saida) is an ecologically significant species that is uniquely adapted to occupy ice edges, but warming and loss of sea ice are hypothesized to favour more facultative gadids, such as walleye pollock (Gadus chalcogrammus).

Towards automated bycatch monitoring: Optimizing and evaluating multi-object tracking of salmon in pollock trawls

Ecological Informatics
Automated tracking of marine life during fishing operations can provide quantitative data on animal movement, improving our understanding of animal behavior, and informing sustainable fishing gear design and use.
