Maternal effects on recruitment of five gadoid species
Abstract Commercial fishing is almost always non‐random and generally removes large and old individuals from fish stocks, thereby reducing age diversity among spawners. Reduced age diversity may result in less stable recruitment. Here, we explore the influence of age diversity (H), mean age of the spawning stock (MA) and sea surface temperature (SST ...

Synchronous and vertically undulating swimming behaviour of Atlantic cod Gadus morhua
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.

State-dependent Energy Allocation in Cod (Gadus Morhua) [PDF]
Growth and maturation are processes that are tuned to the external environment an individual is likely to experience, where food availability, the mortality regime, and events necessary to complete the life cycle are of special importance.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

The Occurrence of Microplastic Ingestion in Commercial Marine Fish in Miri, Sarawak, Malaysia
ABSTRACT Microplastics are polymer‐based particle compositions of various toxic chemicals with size less than 5 mm. Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption.

Saccular cells in the epidermis of Atlantic cod Gadus morhua L.
Infectious diseases are one of the main factors having a negative influence on the Atlantic cod aquaculture. Fish epidermis is a barrier which provides primary interaction between the host and pathogenic organisms.

Sign- and goal-tracking in Atlantic cod (Gadus morhua)
When animals associate a stimulus with food, they may either direct their response towards the stimulus (sign-tracking) or towards the food (goal-tracking). The direction of the conditioned response of cod was investigated to elucidate how cod read cue signals. Groups of cod were conditioned to associate a blinking light (conditioned stimulus, CS) with

ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

The 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.

ABSTRACT Fisheries management relies on accurate stock assessments, which in turn depend on precise age information. Recent molecular tools called ‘epigenetic clocks’ harness age‐related DNA methylation changes to build accurate and precise age‐prediction models.
