THE EFFECT OF THE LIPID AND FATTY ACID STATUS OF ATLANTIC SALMON, SALMO SALAR L., FINGERLINGS ON THEIR PRIMARY DISPERSAL AND FORMATION OF PHENOTYPIC GROUPS
A comparative study of the lipid metabolism in Atlantic salmon fingerlings staying after hatching near their spawning redds along the banks of the Varzuga River main channel (at rapids and riffles) and those who had migrated to tributaries – the Arenga, the Pjatka and the Falaley. The choice of habi...
