CATDOLL : CATDOLL: How many fish can be produced by raising grass carp, silver carp and crucian carp in a newly built cement fish pond of about two acres?

I often hear some aquaculture farmers say that "it is difficult to raise fish in newly built fish ponds." However, as long as the problems of less silt at the bottom of the newly built fish pond, fewer aquatic organisms, poor water quality, and poor disease resistance are solved, the fish in the newly built fish pond will be just as easy to raise. My breeding experience is: Usually after the fish pond is built, the bottom of the pond must be leveled first. If conditions permit, it is best to renovate the bottom of the pond once, loosen the subsoil, and increase the ground temperature and fertility. Then dry it in the sun for about half a month. This can promote the oxygenation and decomposition of organic matter in the fish pond. After the fish pond is dried, a layer of organic fertilizer should be covered on the bottom of the pond. About 200 kilograms of fermented organic fertilizer can be laid on each acre of newly built fish pond. Finally, the fish pond should be thoroughly disinfected. Quicklime is generally used for fish pond disinfection. 70 to 80 kilograms of quicklime are required for each acre of fish pond during disinfection. This.
