First, the goldfish in the aquarium fish culture fish in the paddy field, its habits and eel, squid are similar, so in the rice field to raise goldfish, very appropriate.
1. Breeding method In the paddy field, ditches and fish pits are excavated (should be shallower than other fish). After the rice is planted, when the first plankton peak occurs in the field, the fish species are fed to the rice field for feeding. Plankton is the best food for goldfish. Therefore, goldfish in paddy fields can be fed without bait. Only pay attention to fertilizing and fertilizing water quality, so that the fertilizer can breed plankton, and its water clarity can be kept between 25-30 cm.
2. Fertilization method (1) Apply enough basal fertilizer, which is 1/3 more than normal rice. (2) Pay attention to topdressing. When the paddy field becomes pale and the transparency is less than 30 cm, topdressing should be applied quickly, mainly in decomposed manure or green manure juice. When fertilizing, fertilize the fertilizer into a faint fat juice and splash it all over the place. Apply it with a small amount of times and keep the water clarity at 25 cm. Fertilizer is not less than energy, once the amount of fertilizer is too large, harmful to goldfish.
3. Fishing time Goldfish fishing should be determined by the growth of the fish and the market efficiency. If the fish is of a suitable size and the market price is good, it can be used as needed to catch fish in the fish pit, and it can be caught in the fall.
Second, the rice field is cultivated as a fierce carnivorous fish. When there is insufficient food or there is a difference in size, there are similar killing and swallowing habits. Other small fish are its natural food.
Umbilices feed on fish, worms, and clams at the fry stage, preferring fish and meat. When the feed is insufficient, it can be fed with minced wild fish.
Feeding methods: After the paddy field has been planted, the flooding water should be put in a large amount during the peak season to keep the water color. When the transparency is less than 30cm, topdressing should be performed and soymilk should be splashed in the entire pit and trench. To speed up the development of oysters, oysters, and heads of fish, it is necessary to cultivate fry that is 40 times taller than black scorpion and let it grow up as quickly as possible. This is the live bait of Wuyi in the future. According to tests, for each 1 kilogram of Ukrainian, it costs 4 kilograms of bait. The main point of this technical point is that, when preparing a rice bran for raising rice bran, large numbers of fry, eel, and oysters should be propagated, and then they should be placed in paddy fields or ponds that are to be cultivated. In the middle and late of May, when the water temperature is above 20°C, the black quail will spawn. When the black buckwheat comes out of the membrane and when it can feed independently, it will be put into the middle of the field. The pupa and carp seedlings that are stocked in advance are the best bait for the black puffer.
Rice-field cultivated black plover can be used for large-scale fish breeding. Fish can be harvested as needed, and used as a collocation of wild fish in ponds. When ponds are polycultured, they have 15 to 20 tails per acre.
If the squid and carp seedlings are abundant, they can be grown directly in the rice paddies. When the feed is sufficient, the market size can be reached after 6 to 7 months of breeding. If the Ukrainian turtle is raised too much, it is not ideal because the greater the Ukrainian dragonfly is, the higher the fish bait rate is and the lower the rate of return is.
