Low yields in fish ponds have plagued many rural farmers. Many fish ponds are not small in size and have sufficient water sources. However, the yield is not high, and the efficiency of fish farming is poor. According to an in-depth investigation, the reasons for the low yield of fish ponds are as follows:
The unreasonable stocking rations of irrational stocks or the unreasonable ratio of mixed-cultivated cultivars are most likely to affect the yield. Therefore, stocking fish stocks must be different depending on the water quality, and whether the ratio of polyculture should be considered reasonable. For example: the year-round ponds with good water quality and thin water resources should be mainly grass-raising fish, and the appropriate amount should be used. When the number of mackerel in the pond is large, no longer a large number of carp should be stocked. The main fishing pond should not be equipped with grass carp.
Insufficient illumination Many tall buildings or large trees surround the low-yielding fishing ponds, affecting the light in the fishing ponds. Especially in early spring and late autumn, the temperature of the fishing ponds is low, which affects the feeding of fish. Therefore, the tall objects that can be removed around the fishing ponds Should be removed as much as possible.
Lack of nutrients If there are insufficient natural foods in the fishpond without feeding or feeding, the fish will not grow to the required nutrients, and the fish will not only grow slowly but also become ill. Therefore, according to the needs of different fish for different bait, the fixed-point feeding should be done regularly.
Fish ponds with poor water quality are lean in water quality and there are few plankton in the water. Under such circumstances, farmers should strengthen fertilization or feed. Some fish farmers built the pig houses on the edge of the fish ponds. The pig manure was directly injected into the fish ponds. In hot summer, the animals often caused the fish to lose oxygen and even floated. Therefore, in the peak season of fish growth, reasonable amount of fertilizer should be mastered and often new water should be added, or quicklime should be used to improve water quality.
Fish disease and fish diseases not only affect the growth of fish, but also cause death, resulting in low breeding efficiency. Therefore, healthy fish species should be put in and routinely disinfected prior to release. Fish diseases have to be treated early in the season of high incidence of disease and no disease should be prevented.
In addition, if there are more fierce fish in the fish pond, such as fork fish, ginseng strips, and crabs, etc., they will swallow the fish species, compete for bait and strive for oxygen, affect the production of fish ponds, but also should attract attention.
