Natural mortality (M) is difficult to measure directly in exploited fish stocks. Therefore, in stock assessments, M has usually been assumed to be constant for age classes of fishable size. However, M is likely to vary annually due to temporal change

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. in a fjord in east Iceland, observations of peculiar synchronous and

The feasibility of ranching wild cod in ‘herds’ was compared with three other scenarios: on-growing of wild cod in sea cages, full-cycle cod farming with hatchery produced juveniles, and commercial cod fishery. In the calculations it was assumed

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

In a 5-month experiment where groups of juvenile cod were reared in a flow-through system at low density (Group 1) and in a recirculating system at low (Group 2) and high densities (Group 3), the recirculated water had negative effects on growth rate

The interaction between two species of gadoid and a shrimp stock was studied in a 40 km long two-armed fjord in north-west Iceland. On the basis of acoustic and trawl surveys in 2005 and 2006, immature cod Gadus morhua and haddock Melanogrammus aegle

The effects of different harvesting strategies and increased fish biomass on the feasibility of ranching wild cod in ‘herds’ formed with anthropogenic feeding were studied. The five following scenarios using purse seine as the method of capture w
