Abstract: Although existing fisheries management systems have largely failed, the public and most scientists believe this failure is due to overfishing and that the solution includes the precautionary approach, marine protected areas and ecosystem management. The solutions commonly identified actually treat a symptom rather than the problem. Solutions do exist and have the common characteristics of changing the incentives to make what is good for an individuals or group good for society. Example already in place is the aqua-cultural development which has unveiled to an extent the degree to which fish farm can sustain the economy and provide the necessary protein need of the country. Fish farmer’s sees their business as an answer to the ecological problems associated with over fishing in the wild state and other human impact on rivers. Ecological disease of fish culture caused by poor water quality has posed a serious threat to fishing industry in Nigeria. These stress factors in the environment has been magnified to catastrophic levels in recent times because of the rate of environmental degradation that has been going on unabated. Addressing ecological diseases of fish culture constitute one of the most important steps towards improvement and increasing productivity of fish culture establishment in Nigeria. It is apparent that ecological diseases of fish develop from human anthropogenic impacts on water quality and poor management of the system. Fish farmers can keep their fish in good physical condition and improve productivity by proper design of facilities, good management and good care.
