Fish ponds do not release fish fry, which may be due to the fact that the ponds are not cleaned, resulting in some fish eggs still in the ponds, or they enter the water body by means of birds and insects, thus hatching into fish. Usually, in order to avoid some species harmful to cultured fish in the fish pond, it is necessary to clean the pond first. The pond must be thoroughly cleaned. The whole pond must be sprinkled with quicklime or bleaching powder. The fish can be released after one or two weeks.
raise fish in fish ponds? 1. Release fry: First of all, release fry in fish ponds. Choose high-quality fry. If it is intercropping, you need to prepare a variety of fry, such as grass carp, carp, silver carp, etc. Before releasing the fry, it is necessary to disinfect the fry to prevent it from being infected with insect diseases in the later period. Normally, a batch of fish fry will die after the release, which is usually caused by transportation.
2. Water diversion: Water must be diverted for fish farming, especially for high-density farming, to ensure adequate food. Therefore, in order to fertilize water within a certain period of time, Bacillus and photosynthetic bacteria can be used to promote the reproduction of microorganisms, so that the fry can have enough food, but also inhibit the growth of harmful bacteria. And
3, feed: when that fry grows to a certain size, the fry need to eat feed. Usually choose ryegrass, but can not use too old, otherwise it will cause enteritis, and do not throw overnight grass, the day did not eat need to be fished out at night, so as not to be eaten by fish the next day.
