Aggression and growth as an effect of size composition in groups of Arctic charr

Sammanfattning

Aggressive interactions were initially higher in groups comprised of equally sized large and intermediate Arctic charr Salvelinus alpinus than in groups of small sized individuals and in groups with a normal size distribution. Size composition had no effect on growth. (C) 2002 The Fisheries Society of the British Isles. Published by Elsevier Science. All rights reserved.
