Fish farming is generally domestic fish: silver carp, carp, crucian carp and grass carp.
Fish farming should be graded, and interplanting of various fish species will have good economic benefits.
Silver carp is a kind of fish culture, which is in a subordinate position in the pond where carp, crucian carp, grass carp and bream are raised.
Therefore, fish farming in rural areas should be based on domestic fish farming and reasonable feeding according to the water layer.
1. Pelteobagrus fulvidraco culture
Pelteobagrus fulvidraco is a small scaleless fish with caramel color and bright yellow color. Pelteobagrus fulvidraco is generally natural, living, eating and living by streams and rivers, and is often caught by rivers when it is young. However, it is very rare, so most of the products sold in the sales market are artificially cultured. Pelteobagrus fulvidraco is delicious and nutritious, so people often buy it to make soup. It has a very good practical effect of nourishing and strengthening the body. Pelteobagrus fulvidraco can leave the pond after a one-year growth cycle. Due to the slow growth of Pelteobagrus fulvidraco, it usually comes out after one year's cultivation, with the male fish reaching 0.8- 1 kg/tail and the female fish reaching 0.5-0.8 kg/tail. The cost of breeding is not very high. The total cost of an acre of pond is about 20 thousand yuan, including single tail, pond rent, bait, utilities and so on. However, the output value per mu is still ok. The average net weight is 0.6 kg/tail, that is, the yield per mu reaches 10 kg. According to the current sales market in 35 yuan, the annual output value is RMB, and the net income per mu is RMB after deducting the cost. Therefore, from the profit point of view, there is still a great indoor space development trend in Pelteobagrus fulvidraco culture.
