Problems solved by technology

If you make full use of the idle season before the summer fish species are stocked in the fish species pool, you can interplant crayfish, which will not affect the production of fish species culture, and you can also use crayfish to feed on green feed and natural bait to improve feed utilization and pond utilization. , to increase the economic benefits of breeding, this is a very good continuous breeding method, but there is no such continuous breeding method yet

Abstract

The invention discloses a pond bottom eyebright planting crawfish and fingerling continuous culture method.The pond bottom eyebright planting crawfish and fingerling continuous culture method is characterized by comprising the following steps that 1, pond conditions are selected; 2, a pond is transformed; 3, the pond is prepared; 4, crawfish fry are stocked; 5, daily management of crawfishes is carried out; 6, the crawfishes are caught; 7, eyebright is immersed; 8, fingerling is stocked; 9, daily management of fish culture is carried out; 10, the fishes are caught.According to the method, the space-time resources of the pond are fully utilized, the eyebright is placed in the pond where only fingerling is cultured, feed crops are synthesized through solar energy to be eaten by the crawfishes and the fishes, one season of crawfishes is added on the premise of not influencing the yield of the fingerling, and the aim of increasing income and benefits is achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for continuous cultivation of green crayfish fingerlings at the bottom of a pond. Background technique [0002] Green fish farming at the bottom of the pond has the advantages of saving production costs, land resources, and improving pond utilization. It is an effective way to improve the efficiency of bulk freshwater fish farming. The current method of cultivating fish fingerlings by planting greens at the bottom of the pond is to drain the pond water in winter or spring, sow green forage crops at the bottom of the pond, and after the crops grow to a certain height, stock fish fingerlings, gradually deepen the pond water to submerge the green forages, and the forage crops may be directly eaten by grass. Sexual fish feeding, or rotten fertilizer water to cultivate plankton for fish feeding, supplement feed or fertilizer in the later stage, and cultivate fish species....
