Objectives
Replace the fish meal in salmon diets by l t t i d i b d t tplant protein and avian by-products to
investigate effects on

Conclusions
Reducing the dietary FM from 36 to 5%• Only marginally affected growth
I d th FCR b 8 5%• Increased the FCR by 8.5%• Reduced raw material costs by 31%Reduced raw material costs by 31%• Reduced marine protein use by 76%• Made Atlantic salmon a net producer of
i t i d i 2 5 timarine protein, producing 2.5 times as much as it consumed

Perspectives
• Further growth in aquaculture requires ffi i t f i f d t ffefficient use of marine feedstuffs
• Production and processing of grains• Production and processing of grainsoffers a wide variety of protein sources
• Animal and aquaculture by productsmay be “re circulated” into excellentmay be re-circulated into excellent protein sources for fish
• Salmon farming may becomeindependent of fish meal
