    Sammanfattning : Juvenile rainbow trout (Oncorhynchus mykiss) fed L-tryptophan (TRP) supplemented feed for 7 days show a suppression of aggressive behaviour along with a reduction in post-stress plasma cortisol levels. However, 3 days of elevated dietary TRP does not have any effects on either aggressive behaviour or post-stress plasma cortisol levels. LÄS MER
