Problems solved by technology

Our country has carried out the breeding work of basket fish, but so far, the cultivation of basket fish is limited to seawater cage culture in some areas in the south and brackish water culture in a few areas, and it is mainly used as net cage cleaning fish. Single model, limited breeding area

Embodiment 1

[0018] (1) the breeding pond is an earthen pond of 6 acres, and each pond is furnished with a power impeller type aerator that is 5KW. Before water injection, 20 catties of bleaching powder and 50 catties of tea seed cake are used to clear the pond, and the pond will start to enter water after about 20 days of drying. The water source is filtered water in the river outside the farm, with a salinity of 5-8.

[0019] (2) Fertilize the culture pond with fertilizer and water paste and bacillus, put a small amount of Penaeus vannamei shrimp seedlings into the trial culture after three days, and put the Penaeus vannamei shrimp seedlings into the soil pond at a density of 60,000 / mu after the trial culture. After 15 days of breeding in the middle, the basket fish with an initial body length of 4.16cm was raised in the culture pond with Penaeus vannamei at a density of 100 / mu (the other pond Penaeus vannamei did not add the basket fish to continue breeding as a comparison) , Feed Pena...

[0022] (1) the breeding pond is an earthen pond of 6 acres, and each pond is furnished with a power impeller type aerator that is 5KW. Before water injection, 20 catties of bleaching powder and 50 catties of tea seed cake are used to clear the pond, and the pond will start to enter water after about 20 days of drying.

[0023] (2) Fertilize the culture pond with the fertilizer water paste and bacillus, put a small amount of Penaeus vannamei shrimp seedlings into the trial culture after three days, and put the Penaeus vannamei shrimp seedlings into the soil pond according to the density of 62000 / mu after the trial culture. After 15 days of breeding in the middle, the basket fish with an initial body length of 4.16cm was raised in the culture pond with the Penaeus vannamei at a density of 110 tails / mu (the other pond Penaeus vannamei did not add the basket fish to continue breeding as a com...

Abstract

The invention relates to an ecological breeding method for intercropping Siganus guttatus with Litopenaeus vannamei. The method comprises: (1) cleaning a pond before water enters the pond, after airing the pond in the sun for 18-20 days, starting to make water enter the pond, water salinity being 5-8; (2) before fry releasing, fertilizing water of a breeding pond, after three days, trying to raise Litopenaeus vannamei fries, after trial raising is successful, putting the Litopenaeus vannamei fries in the breeding pond to breed for 15 days, the density of the Litopenaeus vannamei fries being 60000-62000 per mu, and intercropping Siganus guttatus with the Litopenaeus vannamei in the breeding pond, the density of the Siganus guttatus being 100-110 per mu, and feeding Litopenaeus vannamei formula feed every day. Through the breeding method, survival rate of Siganus guttatus is high, and bred Litopenaeus vannamei individual is large, and has less disease. The method is high in average yield and obvious in breeding effect, and has good application prospect.

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 Penaeus vannamei. 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 basket...
