1 Clear Pond Clear Pond is the use of drugs for disinfection, killing pathogens and predators in farmed fish. Clear pond time depends on the efficacy of the drug used, the length of the duration, the size of the toxicity, the weather, and the depth of the water level. Clear pond is too early, fish species did not arrive, the pond will appear new enemy harm; 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 drugs, you can put the fish.
2 Clearing up the wilderness is to pull the net out of the fish pool and stir the bottom mud so that dormant eggs and spores of all kinds of algae and plankton can be propagated early. The peak of rotifers will appear in advance so that the fish will have palatable natural dips. 3 Identification of fish species The characteristics of good fish species are: in the fish pond, agitate the upstream vortex to swim against the water by hand; in the bowl, the body is clean and well-balanced, the tail is full, and the scale fins are intact and non-invasive. Consistent, active and lively; mouth blowing water surface, can top water and swim; drained water, struggling violently, the head and tail can be bent into a circle, and vice versa for the poor seedlings.
4 test the water Before the amplification of batches of fish species, 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, can put a large number of fish into the pool.
5 When the water temperature in the temperature-regulating pond differs from the water temperature in the container of the shipped fish species by more than 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 Select the location of 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 Fertilizing and Casting After the squid is planted in the pool, it is necessary to chase the fermented manure regularly 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 species 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, and a small amount should be matched with herbivorous fish. 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 production. And benefits.
Inspecting ponds once or twice in the morning and evening, it was found that the fish’s predators must be cleared in time, observe the water color and the fish’s activities and feeding conditions, and do fish disease prevention and control work.
