MCS urging use of alternative feeds

A MCS hosted recent event in Edinburgh sponsored by the three main feed manufacturers – EWOS, Biomar and Skretting, highlighted issues in the supply of marine ingredients, the regulatory position in relation to use of animal by-products as well as the advances that have been made in reducing fishmeal usage. 

Fish oil inclusion will have to be reduced considerably if Scottish salmon farmers want to get certified by the Aquaculture Stewardship Council, as limits on wild fish in the diet is a key component of the salmon standard, the MCS said.  

”In the UK we have still have significant use of fish oil only  diets for farmed salmon and the industry can no longer continue to use this valuable resource in this way. It is time to move to a strategic use of our precious and valuable wild capture fisheries. This can only be achieved through a greater level of substitution with alternatives in the diets of farmed fish,” said Dawn Purchase, MCS Aquaculture Officer and continued: 

“There is a wealth of knowledge and research carried out on alternative feed ingredients, both proteins and oils from vegetable sources, algae oil, ragworm and bloodmeal. The UK industry have to be bold and introduce these ingredients into farmed salmon diets, it is the responsible thing to do in a world of limited resources,”   

Purchase pointed out that consumers want healthy, affordable, tasty fish that is also produced responsibly: “A substituted diet can deliver that. Farmed fish reared on high fish meal or fish oil only diets command a premium and will be a luxury for seafood consumers but given that our oceans are fished to maximum capacity the question is whether this luxury  is a responsible one when the alternatives of the future can be used today?”
