Feed costs in aquaculture are generally around 50\u201070% of operating costs and a large proportion of raw materials in feed are imported. The purpose of this report is to compile information on the possibility of utilizing domestic raw materials used in agriculture and fisheries for aquaculture feed. It is considered that the raw materials are generally used for aquaculture and the summary is not limited to individual species. It is possible to use by-products from the fisheries sector as feed in aquaculture, but by-products from the plant kingdom need to be treated in order to reduce \/ eliminate a high proportion of fiber and increase the protein content. By-products of the plant kingdom may be used as food for invertebrates, bacteria and fungi, thus producing a protein-rich product suitable for fish feed.<\/p>\n\n\n\n
Feed cost in aquaculture is about 50\u201070% of the total cost, and most of the feed is imported. The aim of this report is to gather information about utilizing by-products from agriculture and fishing industry as a feed in aquaculture. By-products from the fishing industry can be used as feed in aquaculture but it is necessary to lower the level of fiber and increase protein in by-products from agriculture. This can possibly be done by using the by-products as feed for invertebrates, bacteria and mushrooms and produce protein rich feed for aquaculture.<\/p>","protected":false},"excerpt":{"rendered":"
