Plant based feed ingredients

Raw materials of marine origin are still widely employed in fish feeds. One of the major challenges in fish nutrition is to ensure their successful replacement.

INRA researchers in France for example have shown in the rainbow trout that it is possible to totally replace fish oil by a mixture of vegetable oils without there being any major effects on development and lipid metabolism.

They have also shown in the gilthead sea bream that with an adequate intake of essential amino acids, a 75% replacement of fish meal by plant proteins can be envisaged.

More abstracts from studies can be found on the website from World Aquaculture 2008, held in Korea.
