Method for breeding freshwater shrimp parents by utilizing river crab culture pond

Abstract

The invention discloses a method for breeding freshwater shrimp parents by utilizing a river crab culture pond, which comprises the following steps of a, carrying out preparation before breeding; b, breeding seedlings; c, feeding; d, fishing the parents and separating the parents in different ponds. According to the invention, the freshwater shrimp parents are bred by utilizing superior ecological conditions and sufficient bait resources of the river crab culture pond; the patents bred by the method is higher than parents bred in a special pond in both the aspects of specification and yield; the specification and the quantity of carrying eggs of ovigerous females bred by the method are obviously higher than those of ovigerous females bred in the special pond; culture of river crabs is not influenced; freshwater shrimps mainly eat residual feeds of the river crabs and are properly additionally fed with soybean cakes and bran, so that pond port resources are saved and labor intensity is reduced.

Description

technical field [0001] The invention relates to a method for cultivating freshwater shrimp parents in a river crab culture pond, and belongs to the technical field of shrimp aquatic organism breeding in agricultural aquaculture. Background technique [0002] At present, the breeding methods of freshwater shrimp parents are all cultivated in special ponds. From February to March of each year, the parents of freshwater shrimp are introduced, and they are put into a special pond to start parental cultivation. After the cultivation until the middle and late May, after a large number of freshwater shrimp have eggs, they are transferred to the special pond to raise seedlings. The time for stocking crabs in the river crab breeding ponds is around March. If the parents of freshwater shrimps are cultivated in special ponds, the pond mouth cannot be used for river crab cultivation, and the pond resources cannot be effectively utilized. The river crab breeding pond has a superior ecol...
