HAVBRUKS-Havbruk - en næring i vekst

Innovative use of bioactive marine ingredients as a strategy to sustain growth and health of Atlantic salmon and to improve flesh quality

Awarded: NOK 7.1 mill.

- The present project will evaluate potential growth and health promoting compounds present in marine raw materials that are absent in plant protein sources. Most work on fish meal replacement has focused on essential amino acids and lipids, minerals and antinutritional compounds in plant protein sources. Work carried out by Nofima in Bergen has strongly indicated that marine and vegetable protein sources also vary widely in other small nitrogen containing components or nutrients, which seem to affect fis h growth and health and most likely also fish as health promoting food for humans. - This project will trace and as far as possible identify the feed intake, growth and health promoting bioactive compounds in marine protein sources and study their physio logical implications especially for the functional performance of the salmon intestine. By identification of the essential factors for optimal fish performance, the aquaculture feed industry may optimize for these components in available marine resources or find alternative sources to replace them. The identification of the low molecular weight bioactive compounds will be reached by sequential fractionation of variable types of fish raw material and by-products from the filleting industry. The biological effects of the various fractions will be tested in feeding experiment with salmon. - The experimental work will be important to sustain global growth in aquaculture due to better utilization of marine raw materials and further to support ethical issues i n fish farming and improve the environment by better utilization of aquatic feed.
