Abstract: "For an insight into fish pond Management techniques, this research was focused to review and synthesize pond Management practices in the areas of water quality, fertilization, stocking, feeds and feeding, stock manipulation, diseases, weeds and predators control of major fresh water and brackish water species of fish such as Carp, Tilapia etc. Pond water quality such as temperature, dissolved oxygen, P.11., carbon-dioxide. etc. were elicited as most important in pond management practices since the lives of all aquatic organisms including fish is most dependent on the limnological parameters. Water analysis kit among others were considered very useful for field arid experimental uses. Aeration, Liming, Draining and Refilling of Ponds, etc. were considered most necessary for good water quality. The addition of either organic or inorganic fertilizers to fish ponds result into increased productivity above that possible under natural pond conditions. The stocking rate and stocking density are all dependent on size of fish, feeding regime among others. Supplemental feeding however was noted to bring about greater fish yield in ponds than if the fish were left to feed oniy on the natural foods. Various methods however, were synthesized for use in stock manipulation as found in hybridization, sex reversal, biological stock manipulation among others. The use of chemicals and mechanical methods were found most useful for diseases, weeds and predators control."
