Objectives

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

  • 1. Growth and feed utilisation

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 ti marine protein, producing 2.5 times as much as it consumed

Perspectives

  • Further growth in aquaculture requires

ffi i t f i f d t ff efficient use of marine feedstuffs

  • Production and processing of grains
  • Production and processing of grains
  • ffers a wide variety of protein sources
  • Animal and aquaculture by products

may be “re circulated” into excellent may be re-circulated into excellent protein sources for fish

  • Salmon farming may become

independent of fish meal
