(Anon, 1956). Pre-stocking management. An abundant growth of vegetation is undesirable in the nurseries in view of the wastage of soil nutrition, arresting of The pre-stocking pond management of drainable ponds, which can be dried, is as follows. Draining and drying; Ploughing; Liming; Filling with water and; Fertilization ; Perennial un-drainable water bodies require the following additional pre-stocking management measures. Control of aquatic weeds; Eradication of weed fish and predatory fish and animals. 3.2. Pre-stocking Management . The ponds need to be prepared such that the pond environment provides optimum condition for growth of the fish. The pond environment should be free from predators, aquatic weeds, weed fish; it should have optimum water quality parameters and sufficient natural food should be available in semi- intensive culture systems. The pre stocking management is very important that it affects the success of any fish farming business. However, the type of fish pond preparation depends on the types of fish in use. Example; the fish pond curing is specially applicable to only concrete ponds.

Pre and PostMonsoon Management in Fish Culture. Proper and healthy growth of fish requires adequate supervision, continuous monitoring and management. Timely renovation, stocking of proper size of fish seed, species ratio and stocking number govern the growth rate of fish culture in pre and post monsoon months. Nursery ponds are very important for producing fish seeds/fingerlings. Common carp (Cyprinus carpio) nursery pond management in Rajshahi city was observed for a period of 6 months in 2009.Findings are briefly described here. Pre-stocking management: PRESTOCKING POND MANAGEMENT. It is necessary to manage the pond scientifically to give maximum yield of fish. Fish culture in ponds is basically a three-tier culture system which includes rearing of spawn up to fry (2–3 cm) stage for 2–3 weeks in nursery ponds followed by rearing of 2–3 weeks old fry for about 3 months up to fingerling stage The practices of pre-stocking pond preparation viz., clearance of aquatic vegetation and eradication of predatory and weed fishes are same as discussed in nursery pond management, while measures for control of insects are not necessary in case of rearing pond management. Eradication of predatory and weed fishes is one of the most important steps in pre-stocking management of pond based aquaculture. The chemical piscicides are mostly pesticides of diverse nature, designed for land based agricultural practices. prevention (crop holiday, pond preparation, regulating stocking density, effluent treatment systems) are considered, and national regulations on the use of chemicals in aquaculture and current research being conducted in India are summarized. Recommendations for the improved use of chemicals Pre and post stocking liming doses were 205.7 kg ha–1 yr–1 and 138.4 kg ha–1 yr–1 respectively.

Promote establishment of Bagda shrimp hatcheries in the private sector. Post-stocking pond management After preparing the nursery pond, it is better to maintain optimal physico-chemical properties and plankton. Brown colour of water reveals rich zooplankton growth. To enhance the growth of fish and to increase the production, a package of management practices should be strictly followed.
