A method of observing the spawning behaviour of farmed and wild salmonids in a natural stream habitat
(ICES CM Documents;1993/M:21, Working paper, 1993)When farmed fish escape from farms, they may compete with wild individuals for a number of resources, such as food, spawning sites, and mates. As a part of a larger study on genetic impact from farmed fish on wild ... -
A method to estimate the annual larval production of the Norwegian spring-spawning herring (Clupea harengus L.)
(ICES CM Documents;1997/BB:1, Working paper, 1997)A comprehensive survey in the larval distribution area of Norwegian spring-spawning herring along the Norwegian west coast was carried out annually by the Institute of Marine Research, Bergen in the years 1986-1990. ... -

A system for online assessment of fish welfare in aquaculture
(ICES CM documents;2008/R:18, Working paper, 2008)Aquaculture sea cages can now be more than 30 meters deep. It has therefore become next to impossible for fish farmers to form a complete picture of the welfare situation of the fish. It is consequently all ]important ... -
