    Abstract

    The success or failure of any culture operation is dependant on the water quality and the condition of the bottom sediments. The nature and composition of bottom sediments have several vital roles to play in the productivity of culture ponds. The sediments store the nutrients and effectively control the mineralization of organic deposits at the bottom. They are the source of various organic and inorganic compounds which enter the water after biochemical and chemical changes in situ. The bottom soils provide food and shelter for the bottom dwelling organisms and also act as a bed for the growth of algal flora, which forms the food for many species of fish. Also, they form a substratum for bottom fauna that often constitute an important source of food. The sediments thus play several important and dynamic roles, in the food chain and in the production cycle in the pond eco-system.
