Atlantic cod is a keystone species that remains among the most economically important demersal fish in the North Atlantic. Throughout its distribution range, Atlantic cod is composed of populations with varying environmental preferences and migratory

Food searching behaviour in a group of individually tagged 1-5 kg Atlantic cod Gadus morhua was studied in a set of three experiments in a sea cage with two underwater platforms, where restricted amounts of food was delivered several times per day du

Knowledge of dispersal and migration of juvenile fish is essential for understanding the underlying processes responsible for population structure and recruitment variation. We explored the dispersal patterns of juvenile cod in waters around Iceland

Northern shrimp ( Pandalus borealis ) are considered to represent localized populations in inshore and offshore Icelandic areas, with limited connectivity during adult stages. Due to potentially high larval drift it is unlikely that genetic differenc

To study the effects of anthropogenic feeding on the behaviour of cod (Gadus morhua), a 30 km2 area was reserved in Arnarfjordur, a fjord in Northwest Iceland. At four feed stations, frozen trash-fish was dispensed 2–3 times per week from April 200

About 2200 plaice (Pleuronectes platessa) were tagged on spawning and feeding grounds off Iceland. The aim was to reveal the migration pattern of mature plaice and to estimate fidelity rates to spawning and feeding grounds. From a total of 183 plaice

The vertical and horizontal movements of mature plaice (Pleuronectes platessa) on spawning grounds west of Iceland were studied, using conventional anchor tags and electronic data storage tags measuring depth and temperature at specified time interva
