Diseases have become a primary constraint to aquacultural development, which may affect the achievement of a desired impact for rapid development of fish culture in Nigeria. Apart from causing mortalities, they also cause loss of production quality, reduced growth, reduced fecundity, loss due to control measures and loss due to social factors associated with the farmer. This review has discussed the diseases that are associated with integrated...
