Embodiment 1

[0018] The breeding pond is an earthen pond of 3 mu, and each pond is equipped with an impeller type aerator with a power of 3KW. Before water injection, 20 catties of bleaching powder and 50 catties of tea seed cake are used to clear the pond. After about 20 days of drying, the pond will start to enter water. The water source comes from the filtered water in the river outside the farm. The salinity is 2-5, and the water depth is kept at 1.2. m.

[0019] Plant aquatic plants around and in the middle of the pond. After the aquatic plants grow to 20cm, put young crabs of Chinese mitten crabs. The stocking density of young crabs is 6kg / mu. After 2 months, place the basket fish with an initial body length of 4.16cm according to the The density of 100 tails / mu and the Chinese mitten crab are set in the breeding pond (the other pool of Chinese mitten crab does not add some basket fish to continue breeding as a comparison), and the special compound feed for Chinese mitten crab is fed ...

[0022] The breeding pond is an earthen pond of 3 mu, and each pond is equipped with an impeller type aerator with a power of 3KW. Before water injection, 20 catties of bleaching powder and 50 catties of tea seed cake are used to clear the pond. After about 20 days of drying, the pond will start to enter water.

[0023] Plant aquatic plants around and in the middle of the pond. After the aquatic plants grow to 20cm, put young crabs of Chinese mitten crabs. The stocking density of young crabs is 7kg / mu. After 2 months, place the basket fish with an initial body length of 4.18cm according to the The density of 150 tails / mu and the Chinese mitten crab are set in the breeding pond (the other pool of Chinese mitten crab does not add some basket fish to continue breeding as a comparison), and the special compound feed for Chinese mitten crab is fed ...

Abstract

The invention relates to an intercropping ecological breeding method of Siganus guttatus and Eriocheir Sinensis. The method comprises the following steps: (1) a pond is cleaned firstly before the water enters the pond, the pond is aired for 18-20 days before the water enters the pond, and the salinity of the water is 2-5; (2) aquatic plants are planted around the pond and in the middle of the pond, and then Eriocheir Sinensis juvenile crabs are put in the pond, after two months, the Siganus guttatus and Eriocheir Sinensis are bred in an intercropping mode, and a special compound feed for the Eriocheir Sinensis is fed for two times every day. According to the breeding method disclosed by the invention, after the pond is cleaned, and the average weight of the eriocheir sinensis in the pond where the Siganus guttatus is also intercropped is more than 320 g, and the average weight of the eriocheir sinensis is increased by more than 6.2% compared with that of the Eriocheir sinensis which isnot bred in the pond where the Siganus guttatus is also intercropped; and the yield of the Eriocheir sinensis in the pond where the Siganus guttatus is also intercropped is 150 kg per mu and the yield of the Eriocheir sinensis is increased by more than 19.6% in comparison with the yield of the Eriocheir sinensis which is not bred in the pond where the Siganus guttatus, the breeding effect is remarkable, and the application prospect is good.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an ecological breeding method for nesting fish and mitten crabs. Background technique [0002] Basket fish is a rare omnivorous fish in seawater. It has delicious meat, high protein content and rich polyunsaturated fatty acids, and is deeply loved by consumers. Basket fish has strong adaptability and strong tolerance to salinity and temperature. It can be cultured in most areas south of the Yangtze River in my country. After domestication at a certain salinity, point basket fish can also be cultured in brackish water. Basketfish likes to eat large algae such as Enteromorpha, with miscellaneous feeding habits and a short food chain, which can reduce farming investment and help improve the breeding environment. Sustained development has far-reaching significance. Our country has carried out the breeding work of fish in baskets, but so far, the culture of fish in baskets ha...
