FISH FEED

Legend:

Long Chain Fatty Acids (LCFA)

Linoleic Acid (LA)

Arachidonic Acid (ARA)

Eicosapentaenoic acid (EPA)

Docosahexaenoic acid (DHA)

Fish Oil (FO)

Vegetable Oil (VO)

Microbial Oil (MO)

Due to the generalized use of Vegetable Oil instead of Fish Oil, fish diet is characterize by unbalanced in essential amino acids, the presence of anti-nutritional factors, and palatability problems. The consumption of fish fed with FO substituted by VO, lies to a poor human supply in n-3 LCFAs and the recommended 2-3 fish portions per week do not supply the needed amount of 500 mg/day. Microbial oil will be evaluate to determine its digestibility to fishes and its nutritional properties, when added at established concentration and compared to optimal as well as sub-optimal fish feed formulation. Several authors have reported the need for Essential Fatty Acids (EFA) in rainbow trout where a requirement as percent of dry diet is indicated between 1.0-0.4 for linolenic acid and n-3 LCFAs. The MO produced in MySushi will be able to contribute to cover the recommended consumption, providing a cheap and sustainable supply of EPA+DHA in farmed fish.
