Lake, Reservoir Characteristics Affect Cage Culture Potential

摘要

Culture cages should be installed in areas with good water circulation and not placed in embay-ments with narrow openings or very shallow water. Once stratification occurs, there is no source of dissolved oxygen to the bottom layers of water bodies until they destratify and circulate. Fish stress and mortality can result. Oligotrophic and mesotrophic lakes and reservoirs are better than eutrophic ones as sites for cage culture.
