Abstract

The diseases encountered in mahi mahi, Coryphaena hippurus, in a land-based hatchery, grow-out sea-cages, and from wild populations between 1987 and 1990 were predominately due to protozoan and metazoan parasites. "Milky flesh", or flesh liquefaction post-mortem, due to Kudoa thyrsites, Trichodina gill infections, and eye lesions induced by Benedenia were the most serious infectious diseases of cultured fish. Bacterial diseases were limited to secondary opportunistic infections and fin "rot", and no fungal or viral conditions were detected. Non-infectious diseases included vitamin E deficiency in fry, lateral canal erosions, and miscellaneous dietary and therapeutic toxicities.
