The location should be selected first for fish culture in rural fish ponds. Usually, the fish pond should be located near the water source, which can reduce the cost. It should be noted that the nearby water source cannot be polluted, otherwise a large number of fish will die and cause incalculable losses. In addition, traffic and other factors should be considered, and the power supply should be stable.

After you have chosen the site, you can build the pond. Generally, fish farming requires multiple ponds, because fish of different sizes should be raised separately, so as to avoid big fish eating small fish. The fish pond for raising fry is not too big, usually about 3-5 mu is enough, the water depth is about 1.5 meters, and the fish pond for adult fish needs 8-10 mu.

After the fish pond is built, you can choose fish species. Generally, rural fish ponds are suitable for raising grass carp, silver carp, bighead carp, herring, carp and other common fish. If the conditions are better, some other economic fish can also be raised, but the feeding cost may be higher. In addition, intercropping can be adopted, and 3-4 kinds of fish can be raised in one fish pond.

The stocking density should be paid attention to in fish pond culture. If the stocking density is too high and the fish are permanent to each other, the fish may be injured and cause certain losses, but if the stocking density is too small, the income cannot be guaranteed.
