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

J Fish Dis
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,

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 ...

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

Glob Chang Biol
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 ...

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

Evol Appl
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.
