Can the reservoir raise osmanthus fish?

breeding method

Polyculture is polyculture in adult fish ponds and then polyculture in parent fish ponds. Generally, about 3 cm of mandarin fish species are released in May, and 20-40 fish are released in adult fish ponds with more wild miscellaneous fish (the minimum size of domestic fish culture released should be larger than mandarin fish 1 times), and 30-50 fish are released in each mu of fish pond; More tilapia and crucian carp can be put in adult fish ponds, with 50 ~ 70 fish per mu; About 100 fish per mu are put into the pond where tilapia is over-cultured. Summer flowers such as silver carp and bighead carp should not be kept in ponds where mandarin fish are mixed, because mandarin fish grow fast and will devour small domestic fish. Because Siniperca chuatsi consumes more oxygen than domestic fish, the water quality in the pond where Siniperca chuatsi is mixed should not be too fat, and fresh water should be injected regularly. Siniperca chuatsi is sensitive to drugs, so we should master the accurate concentration when using drugs, and adopt low dose or stop using drugs in the season with high water temperature. The intercropping of Siniperca chuatsi in adult fish ponds mainly uses natural wild fish in the pond as feed, and some parent tilapia can also be intercropped to breed fry for food. Ponds near rivers and lakes where conditions permit can irrigate seedlings in the south of the Yangtze River and introduce wild fish as food. Siniperca chuatsi can be raised for 4 ~ 5 months, and can grow to the commodity specification of about 300 grams, and the yield of Siniperca chuatsi is 5 ~ 8 kilograms per mu.

mandarin fish

Monoculture refers to special pond culture. The pond area is about 1 mu, and the water depth is1.5 ~ 2m. The water quality requires freshness, and the water should be kept trickling. Put about 1000 summer mandarin fish about 3 cm per mu, and reasonably put wild miscellaneous fish such as tilapia, wheat ear fish and shrimp, or minced meat of snails and mussels for mandarin fish to eat. The feeding amount is 3% ~ 5% of the total weight of mandarin fish in the pond.
