Ballan Wrasse - on-growing diets

Offentlig prosjektsammendrag

Today, there are few diets especially developed and well documented for Ballan wrasse for the juvenile and later stages. As an extremely picky fish, with an intestinal system lacking a stomach, development and testing of diets with the right physical and nutritional characteristics for Ballan wrasse, within an acceptable cost frame, is an area of high importance to enable an increased production of this species. In this trial we will test three alternative diets to Otohime S2, currently the only commercially available diet that we have tested and found to give a reasonable good performance. A trial will be run in a duplicate design under semi-commercial conditions, monitoring feed uptake and growth performance over a two months period.
