The Effect of Warmer Water Temperature of Walleye Pollock (Gadus chalcogrammus) Larvae
Journal of the Korean Society of Marine Environment and safety, 2015We examined the effect of warm temperature on the survival of larvae of walleye pollock and on their swimming behavior during the four days of post-hatch. Observations were conducted on larvae in Petri dishes and in 85 cm tall, cylindrical tanks that had a warmer upper layer and cooler lower layer separated by a small thermocline. Mortality was carried

Deep Sea Research Part II: Topical Studies in Oceanography, 2020
Abstract Adult and juvenile (age-1) walleye pollock (Gadus chalcogrammus) were sampled by the US NOAA Alaska Fisheries Science Center summer bottom trawl survey in 2010, 2017, 2018, and 2019 in the northeastern and southeastern Bering Sea, with profiles of temperature collected concurrently.

Aquaculture, 2019
Abstract This study examined the influence of water temperature on the induction of vitellogenin (VTG) in walleye pollocks (Gadus chalcogrammus) in aquaculture. The full-length VTG-A (or VTG-I) gene of walleye pollock was cloned using RACE (Rapid amplification of cDNA ends)-PCR method from liver tissue and recombinant VTG protein (wpVTG) was ...

Deep Sea Research Part II: Topical Studies in Oceanography, 2014
Abstract Walleye pollock ( Gadus chalcogrammus ) and Pacific cod ( Gadus macrocephalus ) are of particular economic and ecological importance in the southeastern Bering Sea. The spatial and temporal overlap of early life stages of both species may explain their strongly correlated recruitment trends. Pelagic larvae and juveniles were collected during

Parasitology Research, 2022
A new microsporidian infecting Gadus chalcogrammus Pallas, 1814 (Gadidae), is described based on morphological, ultrastructural, and molecular studies. This microsporidian parasite develops inside intramuscular spindle-shaped lesions measuring approximately 1-2 mm in width and 4-8 mm in length.

The spatial distributions of marine fish populations are influenced by environmental conditions, intrinsic properties of the populations, and prior distribution. The influence of these factors may not be consistent across age classes. For this study, age composition estimates for walleye pollock ( Gadus chalcogrammus) collected on bottom-trawl surveys

Journal of Fish Biology, 2016
Potential fecundity models of walleye or Alaska pollock Gadus chalcogrammus in the Pacific waters off Hokkaido, Japan, were developed. They were compared using a generalized linear model with using either standard body length (LS) or total body mass (MT) as a main covariate along with Fulton's condition factor (K) and mean diameter of oocytes (DO) as ...

Population Dynamics of Demersal Fish Focusing on Walleye Pollock (Gadus chalcogrammus)
2018Demersal fishes constitute a high trophic level in marine ecosystems. They have relatively long lifespans, and because their biomass does not easily recover after collapse, they are considered more vulnerable to overfishing than pelagic fishes. Like pelagic fishes, the population dynamics of demersal fishes are closely linked to environmental changes ...

A quantitative evaluation of the pollock Gadus chalcogrammus restocking programme in South Korea
Canadian Journal of Fisheries and Aquatic SciencesThe collapse of the Korean pollock ( Gadus chalcogrammus) stock in the late 1990s is hypothesised to be due to environmental changes, overexploitation, or a combination of both factors. However, due to limited data availability, no conclusive scientific analysis is available to support any of these hypotheses.
