1. Clear ponds Clear ponds use drugs to disinfect pathogens and predators in farmed fish. Clear pond time depends on the efficacy of the drug used, duration, toxicity, weather, and water level. Clear pond is too early, fish species did not arrive, the pond will appear new predators; too late, the toxicity has not disappeared, easily lead to fish poisoning death. After the exposure of the pond into a small amount of water to carry out water detoxification, with about 100 kg of lime per acre, into a slurry of lime, the whole pool evenly spilled, 7 to 10 days after the disappearance of the drug, you can put the fish.
2, clear field clearing is the fish in front of the pool to pull the net, stir the sediment, so that a variety of algae and plankton dormant eggs, spores early reproduction, the emergence of rotifer peak in advance, so that the fish have a palatable natural dip material.
3, identification of fish species constitution strength is a good fish species, in the fish pond, by hand to stir the vortex to swim against the water; swim in the bowl, the body is clean and well-balanced, full back, scales fin intact atraumatic, Consistent specifications, swimming and lively; mouth blowing water surface, can top water and swim; drained water, struggling violently, head and tail can be bent into a circle, and vice versa is the difference between seedlings.
4, test water Before the enlarged batch of fingerlings, the first to take the pool water to test, if the test fish in the pool water 24 hours without death and no abnormal reaction, before they can put a large number of fish into the pool.
5. When the temperature difference between the water temperature in the temperature-controlled pond and the water temperature in the container of the shipped fish species exceeds 5°C, the water temperature shall be adjusted. When the temperature difference is reduced to the allowable range, the fish species shall be lightly put into the pool.
6, choose to place the fish should generally be placed in the deep water of the pool water head, so as not to be caught in the pool or stirred up by drowning.
7. After fertilizing and casting squid, it is necessary to chase the fermented manure regularly after it is planted in the pool to keep the pool water brown or oil green. In the early stage, yellow flour and wheat husk should be properly fed, and the amount of fish fed should account for about 5% of the fish's body weight.
8. The stocking density and proportion of rational stocking fish must be determined according to the size of the pond itself, the depth, the fatness, the water source, and the aeration setting. For example, the more pooled water should be dominated by filter-feeding fish and supplemented by omnivorous fish, with a small amount of herbivorous fish, and the proportion of fish in each layer of water should be taken into consideration to achieve reasonable polyculture and make full use of water to increase yield. And benefits.
9. The patrol pond will be patrolled once in the morning and evening. It is found that the enemy’s fish should be promptly removed, observe the water color and the fish’s activities and feeding conditions, and do fish disease prevention and control work.
