Potential utilization of mussel meals as an alternative fish feed raw material for aquaculture

Increasing the target of aquaculture production will increase the need for feed which an increase will follow in the need for fish meal. The constraint in aquaculture fish feed dependence on a fish meal import is known. In efforts to find local raw materials to reduce dependence on fish meals, one source of quality animal protein from marine resources as raw material for feed that needs to be studied and developed is mollusks or mussels. This review summarizes the use of mussel meal in aquaculture feed and is expected to provide a comprehensive overview of the existing studies’ potential on mussels meal used as a feed ingredient in fish feed. Many species of mussel have been tested for raw material in fish feed such as blue mussel (Mytilus galloprovincialis), Freshwater mussels (Anodonta anatina & Unio mancus), Mytilus edulis L and Green mussel (Perna viridis). Mussels contain high levels of nutrients and bio-actives which were utilized in the form of mussel meals for feed ingredients. The constraint mussels have high heavy metals such as Pb, Hg and Pb. The utilization of mussel meals as a source of protein feed could increase the growth of several types of cultured fish. One alternative used organic acid as a feed additive to reduce toxicity of heavy metals in fish. The conclusion is that mussel meals have the potential as raw material and an alternative protein source to reduce dependence on a fish meal in aquaculture fish feed.
