Five methods of clearing ponds before the release of fish species

Pond conditions for culturing adult rainbow trout in ponds

In general, adult fish are raised with fish that have been raised for more than one year, and some have been raised from the beginning of the year until commercial fish come out of the pond. However, no matter what kind of culture method, in order to achieve high yield and high efficiency, it must be fully developed.

There are many benefits to sunning ponds in winter
The author recently visited Xingyang rural areas in our province and found that many fishermen friends quickly disinfected the fish pond after selling out the commercial fish, and then put the fish species in proportion. They think that this will enable fish species to adapt to the pond environment early so that they can open their mouths and grow early in spring. In fact, it is better to expose fish ponds, especially aged fish ponds, to butterflies in winter. The aging of fish ponds is aggravated by the accumulation of fertilizer feed residues, fish feces and sediment impurities, which directly affects the aging of fish ponds in the next year.

Technique of main culture of freshwater Pomfret in shallow ponds
Among the existing ponds, shallow ponds still account for a large proportion. The water of this kind of pond is shallow, the drainage and irrigation is not matched, some are seasonally flooded into ponds, breed traditional fish, produce little fish, the benefit is very low. In order to explore the ways to increase production, increase income and increase efficiency of this kind of ponds, for two consecutive years from 1993 to 1994, we have a total area of 9.7 mu and a maximum water depth of 1. 5%. The experiment of main culture of freshwater Pomfret in shallow ponds was carried out in rice ponds, and satisfactory results were obtained in the absence of oxygen enrichment facilities: an average yield of 227 kg per mu in 1994.
