Growth patterns of Arctic charr in five high altitude lakes in a French Alpine massif

The growth of Arctic charr Salvelinus alpinus in five high altitude lakes differed between lakes during the first 2 years but was similar thereafter. The average temperature during the summer had a direct effect on growth and an indirect effect on the productivity level of the lakes, particularly on...

Description
Summary:The growth of Arctic charr Salvelinus alpinus in five high altitude lakes differed between lakes during the first 2 years but was similar thereafter. The average temperature during the summer had a direct effect on growth and an indirect effect on the productivity level of the lakes, particularly on the abundance of planktonic crustaceans. The results highlight the importance of planktonic crustacea in the growth of Arctic charr. Copyright 2002 The Fisheries Society of the British Isles
