Widespread Phenological Shifts With Temperature in Alaska's Marine Fishes [PDF]

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
We investigated changes in the phenology of early life stages of fishes in the Gulf of Alaska and Bering Sea. Larval size on a standardized date was used as a proxy for larval developmental timing in spring. For most species, interannual variation in mean size‐at‐date was significantly and positively related to temperature, demonstrating widespread ...

Purification of Alaskan Walleye Pollock (Gadus chalcogrammus) and New Zealand Hoki (Macruronus novaezelandiae) Liver Oil Using Short Path Distillation [PDF]

open access: yesNutrients, 2014
The beneficial health effects of a diet rich in n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) have been extensively researched in recent years. Marine oils are an important dietary source of n-3 LC-PUFA, being especially rich in two of the most important fatty acids of this class, EPA (eicosapentaenoic acid; 20:5n-3) and DHA ...

О сроках сохранения фертильности икры и эмбриональном развитии минтая Gadus chalcogrammus (Gadidae) северной части Охотского моря

open access: bronzeBulletin of the North-East Science Center, 2023
Experimental work was carried out to find out the timing of the fertility preservation for eggs remaining in the body cavity of the North Sea Alaska Pollock females after spawning, as well as the possibility of their normal course of embryogenesis. It was established that eggs remaining after spawning in the pollock female body cavity are not resorbed ...

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

open access: yesJournal 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 ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway [PDF]

open access: yesJournal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

Genetic Data Reveal Nonlocal Juvenile Recruitment and Variable Seasonal Movement of a Highly Mobile Marine Fish Across Alaska [PDF]

open access: yesEvolutionary Applications, Volume 19, Issue 1, January 2026.
ABSTRACT Movement patterns of marine fish are often difficult to accurately define given seasonal variation, ontogenetic shifts, and changing environmental conditions. However, outlining movement is crucial for understanding population dynamics, as well as for conservation and management efforts.

Habitat and Trophic Specialization Among Greenland Cod (Gadus ogac) Morphotypes in the Context of Climate Change Resilience [PDF]

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Morphological variation and habitat‐trophic metrics from carbon (δ13C) and nitrogen (δ15N) stable isotopes were estimated in Greenland cod (Gadus ogac) collected along the marine coast near Ulukhaktok, NT, in the western Canadian Arctic. This study provides critical insights into the ability of coastal Arctic Gadids to respond to shifts in resource use

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

open access: yesEcology, Volume 106, Issue 10, October 2025.
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.

A Life Stage-based Model for Assessing the Walleye Pollock Gadus chalcogrammus Population in the East Sea

open access: diamondKorean Journal of Fisheries and Aquatic Sciences, 2017
Since the late 1990s, walleye pollock Gadus chalcogrammus fisheries in Korean waters have been considered collapsed. Although many fisheries scientists suspect that the collapse might have been triggered by overexploitation of juvenile pollock or environmental changes, such conjectures have been nei...
