Major objectives of an integrated fish culture are:
to reduce operating costs and maximize the farmer's income.
to develop a more economic ration for fish from wastes to useful fish protein production.
to solve the waste management problem.
to controle the pollution problem associated with livestock (in the form of fly and odour).
As manure is the major factor controlling fish production in an integrated fish farming system, research efforts should be concentrated on its utilization and management, using fish production and economic benefits as its function.
Based on this review the following priority areas of research are proposed.
Standardization of procedure for manure application including frequency, rate and method of application for increased fish production.
Studies on stocking densities and stocking ratios and harvesting of fish in manured ponds.
Application of organic wastes to fish ponds in terms of ‘BOD’ and ‘COD’ loading.
Development of supplementary fish diets from wastes of animal and agricultural farms.
Studies on the effect of manuring on fish health, taste and texture of fish meat and sanitation.
Determination of chemical and organic constituents of manures (green and animal).
