Application of simple facilities for temporary Fish Culture
At present, there are many flowing aquaculture farms in Sichuan, which mainly breed some cold-water fish, and most of their breeding facilities are cement ponds. In the earthquake, these cement pools are damaged to some extent by the earthquake destructive force, which may cause pool leakage and so on. If it is not repaired in time, the water in the pond may be lost, which will cause a crisis to the survival of aquaculture aquatic organisms, and even all the water in the pond will run out, resulting in the death of aquaculture aquatic organisms and huge economic losses to farmers. If you want to

How to improve the utilization rate of idle fish ponds in winter
After merging ponds in winter to releasing summer flowers in the following year, most fish ponds have a free period of about half a year. If they are comprehensively utilized, the utilization rate and economic benefits of fish ponds can be greatly improved. Here are four ways to make use of winter fry ponds. The cultivation of adult fish in winter fallow ponds can not only increase production, but also adjust the "summer shortage" of the aquatic product market. Due to the short culture period and low temperature, the following techniques should be adopted: ① should be released in advance, that is, after the fish species are merged into the pond.

Technical measures of rice-fish rotation
To make preparations before raising fish, we must first raise and strengthen the ridges of the fields. Combined with the seedling or whole field of early rice, the ridge of the field should be heightened and widened as the basis of the later stage. After the harvest of early rice and the return of late rice, the ridge should be raised to more than 1.5 meters in time, and the width of the ridge should be about 1.2 meters. Secondly, it is necessary to do a good job in temporary recuperation ponds. The temporary pond is excavated in a corner of Honda, with an area of 15% to 20% of the size of rice fields. The depth of the temporary pond is about 1 meter. Finally, a drainage ditch was opened at a convenient end of the field to prevent the flood from rushing into the pond and causing the fish to follow the water.
