Problems solved by technology

At present, the size of river crab farming across the country is still generally small. The overall size is: female crabs are mostly 125-135g, and the average number of male and female crabs is more than 150g. The price of crabs is naturally more expensive; and due to a single defect in the breeding method, the yield and quality of river crabs cannot be improved

Embodiment 1

[0017] The method of high-yield intensive breeding of river crab includes the following steps:

[0018] 1. Pond selection: build a breeding pond of 50 acres with a depth of 2m, design a shallow shoal in the aquaculture pond, the water level of the shoal after irrigation is 70cm, the area of ​​the shoal accounts for 70% of the total area of ​​the entire aquaculture pond, dig more in the shallows A horizontal ditch. The depth of the horizontal ditch is 60cm lower than that of the shoal. There should be a ring groove around the breeding pond, and the depth of the ring ditch should be 1m lower than the location of the shoal; a good water source is required around the breeding pond, with good water quality and no pollution;

[0019] 2. Pond treatment: clean up the lobsters and wild fishes in the aquaculture pond, and sun the pond from October to November every year. The degree of the sun pond is that the bottom of the aquaculture pond is evenly cracked and the crack is 2.5cm. Construct ...

Embodiment 2

[0026] The method of high-yield intensive breeding of river crab includes the following steps:

[0027] 1. Pond selection: build a breeding pond of 30 acres with a depth of 1m, design a shallow shoal in the aquaculture pond, the water level of the shoal after irrigation is 60cm, the area of ​​the shoal accounts for 60% of the total area of ​​the entire aquaculture pond, dig more in the shallows A horizontal ditch, the depth of which is 40cm lower than that of the shoal; there should be a ring groove around the breeding pond, and the depth of the ring should be 0.8m lower than the position of the shoal; a good water source is required around the breeding pond, with good water quality and no pollution ;

[0028] 2. Pond treatment: clean up the lobsters and wild fishes in the aquaculture pond, and sun the pond from October to November every year. The degree of the sun pond is that the bottom of the aquaculture pond is evenly cracked and the crack is 1.5cm, and it is in the pond. Cons...

Abstract

The invention discloses a high-yield intensive culture method for river crabs. The high-yield intensive culture method for river crabs comprises the following steps of selection of a pond, treatment of the pond, selection of juvenile crabs, feeding, management of feed, other management and the like. By the intensive culture method, the yield of the river crabs is improved, the specification is further increased, the number of male and female river crabs with the average weight equal to or above 150 g accounts for 60-70%, and therefore, the economic benefit of cultivation is increased.

Description

Technical field [0001] The invention relates to a method for breeding river crabs, in particular to a method for high-yield and intensive breeding of river crabs. Background technique [0002] River crab is the most important freshwater crab in our country. Its meat is fresh and tender, tastes delicious, and is extremely nutritious. Due to the strong adaptability of river crabs and the wide range of breeding, the scale of breeding has increased rapidly in recent years. At present, the size of river crab farming in the country is still generally small. The overall size is: female crabs are mostly 125-135g, and the number of male and female crabs above 150g is relatively small. The price of river crabs will vary according to their individual size. The price is naturally more expensive; and due to a single defect in the breeding method, the yield and quality of river crabs cannot be improved. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior...
