Farm-raised fish (aquaculture)
are the least-expensive fish available. Common farm-raised fish are tilapia, catfish and barramundi. Keep in mind, wild-caught fish are not renamed to substitute for a farm-raised one. More likely, the converse is the case. The less expensive farm-raised fish are substituted for a wild-caught fish. The majority of substitutions are driven more by a lack of availability of a preferred wild-caught fish.
