Cd. Levings et al., FEEDING OF ATLANTIC SALMON (SALMO-SALAR L) POSTSMOLTS IN A FJORD IN CENTRAL NORWAY, Canadian journal of zoology, 72(5), 1994, pp. 834-839
The feeding habits of postsmolt Atlantic salmon (Salmo salar) caught b
y two-boat trawling were studied in Trondheimsfjord in central Norway.
Fish caught in the inner fjord near the estuaries of the Orkla and Ga
ula rivers had recently fed on food produced in freshwater and estuari
ne habitats, namely stonefly and mayfly nymphs and gammarid amphipods.
Stomach contents of postsmolts caught farther seaward were dominated
by adult insects, with smaller proportions of the food volume originat
ing from marine pelagic (larval fish, hyperiid amphipods, calanoid cop
epods) and nearshore (gammarid amphipods) habitats.
