Pond crab strengthened breeding method

Abstract

The invention discloses a pond crab strengthened breeding method. The method includes a, pond improvement and construction; b, preparatory work prior to stocking; c, juvenile crab placement; d, breeding management. Compared with the prior art, the method has the advantages that the juvenile crabs are bred in concentrated and strengthened manners, the physique is strengthened, and the survive rate after stocking is increased; the juvenile crabs are placed into a commercial crab breeding pond in the middle third of the May, a traditional placement time is avoided, the time for planting water plants in the pond is sufficient before the juvenile crabs are placed into the pond for breeding, and fine environment for middle and rear periodical molting and growth is provided for Chinese mitten crabs; the quality and quantity of the juvenile crabs stocked in the pond in May are grasped clearly, and the blindness of feed placement is avoided.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for breeding river crabs, in particular to a method for intensively cultivating crab species in a pond to improve the survival rate of river crab (commercial crab) breeding. Background technique [0002] The main shortcomings of the existing river crab (commercial crab) pond culture technology are: first, the source of the seed is complicated, the quality is uneven, and the physique of the seed is poor after long-distance transportation, resulting in a huge difference in survival rate after the pond; Farmers do not know how many crab species survive in the pond, so there is a lot of blindness in feed feeding and production management; third, crab species have been in the pond when aquatic plants are planted, and the aquatic plants are eaten by the crab species as soon as they sprout. Aquatic plants cannot grow well and cannot provide a good ecological environment for the gr...

Problems solved by technology

[0002] The main deficiencies in the existing river crab (commercial crab) pond culture technology are: the first is that the seed source is complicated, the quality is uneven, and after long-distance transportation, the seed physique is poor, resulting in a great difference in survival rate after going to the pond; It is because the farmers do not know how many crab species are surviving in the pond, so there is a lot of blindness in bait feeding and production management. Aquatic plants cannot grow well, and cannot provide a good ecological environment for the growth of river crabs, so it is difficult to ensure the normal and rapid growth of river crabs
