Problems solved by technology

However, river crabs and crayfish began to be mixed very early. Both are benthic animals. When mixed, crayfish affect the survival and molting of river crabs, thereby affecting the size and output of river crabs.

Embodiment 1

[0038] Follow the steps below to carry out the cultivation of California perch in double crop rotation in ponds with crayfish and river crabs:

[0039] 1. Pond preparation: Prepare two ponds, one large and one small. The large pond is 12 mu as the main pond, and the small pond is 2 mu as the crab temporary pond. The area ratio of the main pond and the temporary pond is 6:1. On the 10th, aquatic plants (Elodea) were planted in the entire pond, and the pond was equipped with a microporous aeration system at the bottom to ensure that the crayfish were not hypoxic.

[0040] S2. Temporary breeding in the special pool for crab seedlings: on March 5, after the aquatic plants grow well, stock high-quality crabs in the temporary breeding pond. The stocking density is 10,000 / mu, and the stocking size is about 5g / piece.

[0041] 3. Stocking and breeding of lobster seedlings: On April 3rd, the crayfish seedlings were stocked in the main pond, the stocking density was 6,000 / mu, the stockin...

Embodiment 2

[0049] Follow the steps below to carry out the cultivation of California perch in double crop rotation in ponds with crayfish and river crabs:

[0050] 1. Pond preparation: Prepare two ponds, one large and one small. The large pond is 14 mu as the main pond, and the small pond is 2 mu as the crab temporary pond. The area ratio of the main pond and the temporary pond is 7:1. On the 5th of May, the whole pond was planted with aquatic plants (Elodea), and the pond was required to be equipped with a microporous aeration system at the bottom to ensure that the crayfish were not hypoxic.

[0051] S2. Temporary breeding in the special pond for crab seedlings: on March 10, after the aquatic plants grow well, stock high-quality crabs in the temporary breeding pond. The stocking density is 9000 / mu, and the stocking size is about 5g / piece.

[0052] 3. Stocking and breeding of lobster seedlings: On April 6th, the crayfish seedlings were stocked in the main pond, the stocking density was 8...

Embodiment 3

[0060] Follow the steps below to carry out the cultivation of California perch in double crop rotation in ponds with crayfish and river crabs:

[0061] 1. Pond preparation: Prepare two ponds, one large and one small. The large pond is 20 mu as the main pond, and the small pond is 2.5 mu as the crab temporary pond. The area ratio of the main pond and the temporary pond is 8:1. Aquatic plants (elodea) were planted in front of the entire pond on the 2nd. The pond is required to be equipped with a microporous aeration system at the bottom to ensure that the crayfish are not hypoxic.

[0062] S2. Temporary breeding of crab seedlings in a special pond: On March 20, after the aquatic plants grow well, stock high-quality crabs in the temporary breeding pond. The stocking density is 12,000 / mu, and the stocking size is about 5g / piece.

[0063] 3. Stocking and breeding of lobster seedlings: On April 8th, the crayfish seedlings were stocked in the main pond, the stocking density was 5000 / ...

Abstract

The invention belongs to the technical field of aquaculture and discloses a culture method for double alternate culturing and intercropping lobster and river crab ponds with microptenus salmoides. The method comprises pond preparation, temporary culture of juvenile crabs in a special pond, stocking and culture of lobster seedlings, stocking of microptenus salmoides fries, catching and marketing of lobsters, stocking and culture of juvenile river crabs after temporary culture, utilization of a temporary culture pond, daily management, catching and marketing of river crabs and microptenus salmoides and other steps. The growth characteristics and life habits of the river crabs, the lobsters and the microptenus salmoides are comprehensively considered, the space of the pond is used to culture the lobsters firstly in the early stage of growth of the river crabs, the river crabs are mainly cultured after the lobsters are caught before the end of July, the culture pond is interplanted with microptenus salmoides for control of small trash fish in the pond, and the utilization rate and the economic benefit of a crab pond are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating California perch in double-crop rotation in a pond. Background technique [0002] River crab, scientific name Chinese mitten crab, crayfish, scientific name Procambarus clarkii, both are very important special aquaculture species in China, and are cultivated in Jiangsu, Hubei, Anhui and many other provinces. Because river crabs and crayfish are both benthic crustaceans, the activities of the crayfish are not conducive to the growth of river crabs when they live together, and will reduce the survival rate of moulting of river crabs. Therefore, in farming practice, many farmers use quicklime, bleaching powder and other drugs to clear the ponds before stocking crab species in the river crab ponds at the beginning of the year, so as to kill crayfish and other organisms. However, in the early stage of crab breeding (before the end of July), th...
