Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Seal haulout behavior is of interest in relation to energetics and abundance estimation. To assess year‐round and diel haulout patterns and estimate correction factors, data were obtained from 100 seals (66 harbor and 34 gray seals) tagged with satellite transmitters in Kattegat and the western Baltic Sea during 2004–2017.

Ecology and SocietyThe regime shift concept is a popular scientific framework to analyze abrupt changes in marine ecosystems. The collapse of North Sea cod ( Gadus morhua ) represents a paradigmatic example of such a change.

Nutrition in cod (Gadus morhua) larvae and juveniles [PDF]
ICES Journal of Marine Science, 2006 AbstractOver the past few years, great progress has been made in culturing cod larvae in indoor hatcheries using rotifers and Artemia or formulated feed as start-feed (intensive systems). However, when compared with natural systems based on copepods grown in seawater lagoons, the growth potential has not been fulfilled, and deformities of larvae and ...

Economic impacts of changes in fish population dynamics: the role of the fishermen’s harvesting strategies [PDF]
Using a bioeconomic model of the cod (Gadus morhua) and capelin (Mallotus villosus) fisheries of the Barents Sea, this study assesses the role of the fishermen’s behavior in reducing or intensifying the effects on the stocks caused by altered population ...

A Review of the Applications and Challenges of Pulsed Electric Fields in Fish Ecological Protection
Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT The use of pulsed electric fields (PEF) to regulate fish swimming patterns, especially during migratory channel restoration in dammed rivers, faces significant operational challenges. These challenges can generally be attributed to the multifaceted nature of fish behaviour and limitations in research on physical interception methods.

Synchronous and vertically undulating swimming behaviour of Atlantic cod Gadus morhua
Aquatic Biology, 2013 Predatory fish often forage in schools, but observations of actual schooling behaviour in deep-water ecosystems are scarce. In a ranching study of wild Atlantic cod Gadus morhua L.

Early Post‐Release Movement Convergence in Reintroduced Giant Pandas
Ecology and Evolution, Volume 16, Issue 6, June 2026.We used high‐frequency GPS tracking of eight reintroduced giant pandas (474 tracking days) to test how extreme energetic constraints shape movement during early post‐release adjustment. Principal component analysis of ten daily movement metrics revealed two independent movement axes (exploration–exploitation and tortuosity–consistency), and an ...
