Embodiment 1

[0025] (1) Pond preparation: Choose a rectangular pond with a depth of 50 mu and a water depth of 1 meter in an east-west direction in a place with sufficient water sources. A nano-aeration tube is arranged in parallel at the bottom of the pond every 5 meters, equipped with a 5 kilowatt blower, and 3 holes are excavated beside the pond A deep well with water with a salinity of 30‰ can be introduced to remove the sludge at the bottom of the pond, soak the pond with 75 kg of quicklime per mu for 8 days in water with a depth of 20cm, drain the pond water, and expose the pond to the sun for 30 days. Inject fresh water that meets the national fishery water quality standards to a depth of 1 meter in the pond, and introduce water with a salinity of 30‰ from a deep well into the pond to keep the final salinity of the pond water at 3‰. Add 20 kilograms of fermented chicken manure per mu to the pond for fertilizer and water, and use soil to separate 2 mu of shrimp seedlings in a corner o...

Embodiment 2

[0032] (1) Pond preparation: Choose a rectangular pond of 40 acres and a water depth of 1 meter in an east-west direction in a place with sufficient water sources. A nano-aeration tube is arranged in parallel at the bottom of the pond every 5 meters, equipped with a 5 kilowatt blower, and 3 holes are excavated beside the pond. It can be introduced into a deep well with water with a salinity of 30‰; to remove the sludge at the bottom of the pond, add 75 kg of quicklime per mu to the water with a water depth of 20cm to soak the pond for 10 days, drain the pond water, and expose the pond to the sun for 35 days. Inject fresh water that meets the national fishery water quality standard to a depth of 1 meter in the pond, and introduce water with a salinity of 30‰ from a deep well into the pond to keep the final salinity of the pond water at 3.5‰. According to 25 kilograms of fermented chicken manure per mu, add in the pond and carry out fertilization and water, separate the shrimp se...

Abstract

The invention relates to a mixed breeding method of carassius auratus gibelio and penaeus vannamei boone. The method comprises the steps of pond preparation, fingerling and young shrimp putting, bait feeding, breeding management and capturing. The mixed breeding method of the carassius auratus gibelio and the penaeus vannamei boone is simple, the breeding cost is low, the breeding yield can be greatly increased, the total revenue of breeding of the carassius auratus gibelio and the penaeus vannamei boone is improved, and a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the field of heterogeneous gibel carp culture, in particular to a mixed culture method of heterogeneous gibel carp and Penaeus vannamei. Background technique [0002] The heterogeneous gibel carp is an important freshwater aquaculture species in Jiangsu Province. It has high yield and high economic benefits. The commercial fish are exported to all parts of the country and exported to South Korea and Japan. However, in recent years, with the continuous expansion of the breeding scale, the occurrence of diseases has become more and more serious, causing heavy losses to the farmers. [0003] my country has accumulated mature experience in fish polyculture technology. Regarding the polyculture of Penaeus vannamei and fish, it has been reported that it is with tilapia, grass carp, silver carp, bighead carp, yellow catfish, mullet, etc. , and most of them are polycultured with a single species of fish. However, there are not many st...
