Embodiment 1

[0026] (1) Pond conditions. The test site is located in Dongxin Farm, Lianyungang. The breeding pond covers an area of ​​100 mu. The pond is oriented east-west with good ventilation. The water depth is 2.0 meters. 8 machines.

[0027] (2) Breeding preparation. Clear ponds should be thoroughly cleaned, excess silt should be removed, and 10cm of bottom mud should be retained; sun-dried ponds should be fully dried for 60 days, disinfected, and disinfected with quicklime and bleaching powder dry pond method, with 120kg of quicklime or 25kg of bleaching powder per mu, 10cm of water inflow, soaking for 5 sky. Apply 150kg of fermented chicken manure per mu before entering the water, and sprinkle it in the shallow water area as a base fertilizer, and then fill the pond with exogenous water to a depth of 0.8m.

[0028] (3) Fry stocking. Select Penaeus vannamei shrimp seedlings that are harmless and disease-free, with neat and uniform specifications, and have a standard thickness of...

Embodiment 2

[0037] (1) Pond conditions. The test site is located in Hai'an Hualiu Aquatic Products Company. The breeding pond covers an area of ​​35 mu. It is rectangular, east-west direction, and the water depth is 2.5 meters. Taiwan, a complete set of electrical equipment, stable water and electricity supply, and very convenient transportation.

[0038] (2) Breeding preparation. One month before the seedlings are released, dry ponds are used, 100 kilograms of quicklime is used per mu, and the whole pond is sprinkled after watering and slurrying, including the pond edge, pond ridge and pond bottom, in order to kill pathogens and enemies in the pond. pests. Fill the pond with water every half a month or so, and filter it with 60-mesh sieve silk to prevent wild fish and shrimp from entering the pond. Afterwards, 100 kilograms of fermented organic fertilizer (chicken manure) per mu is used to cultivate water quality, making the water in the pond yellowish-brown or yellow-green.

Embodiment 3

[0046] (1) Pond conditions. The test site is located in Dongxin Farm, Lianyungang. The aquaculture pond covers an area of ​​30 mu. It is well ventilated from east to west. The water depth is 1.8 meters.

[0047] (2) Breeding preparation. Clear ponds should be thoroughly cleaned, excess silt should be removed, and 10cm of bottom mud should be reserved; ponds should be fully dried, dried for 30 days, sterilized, and disinfected with quicklime and bleaching powder dry pond method, using 110kg of quicklime or 25kg of bleaching powder per mu, entering 10cm of water, soaking for 3 sky. Apply 100kg of fermented chicken manure per mu before entering the water, and sprinkle it in the shallow water area as a base fertilizer, and then fill the pond with exogenous water to a depth of 0.8m.

[0048] (3) Fry stocking. Select Penaeus vannamei shrimp seedlings that are harmless and disease-free, with neat and uniform specifications, and have a standard thickness of 160,000 / kg after desalin...

Abstract

The invention discloses a method for intercropping ictalurus punctatus and penaeus vannamei, and the method is characterized by comprising the steps of pond selection, breeding preparation, fry stocking, water quality regulation and control, feed feeding, disease prevention and control and the like. According to the method for intercropping the ictalurus punctatus and the penaeus vannamei, an original ecological environment of a pond can be changed, the constitution of the penaeus vannamei is enhanced, the body vitality of the penaeus vannamei is improved, the body immunity of the penaeus vannamei is enhanced, the digestion, absorption and utilization rate of bait can be increased, and disease is reduced. Residual feed, excrement, organic chippings and the like of the penaeus vannamei arefully utilized after polyculture of the ictalurus punctatus, the content of pollutants is reduced, the virtuous cycle and relative stability of pond ecology are promoted, so that the penaeus vannameiis prevented from pathogeny, and the quality and comprehensive economic benefits of vannamei products are improved. The breeding method is simple, the quality is high, the disease is less and the benefit is good.

Description

technical field [0001] The present invention relates to a kind of aquaculture technology, especially a kind of technique that improves the disease resistance ability of Penaeus vannamei by nesting channel catfish in a culture pond of Penaeus vannamei, specifically a kind of nest breeding of channel catfish and Penaeus vannamei Methods. Background technique [0002] Channel catfish (Ietalurus punetaus) belongs to Siluriformes and Catfish family. It is native to the United States. It has the characteristics of fast growth, wide temperature range, and strong disease resistance. Its meat is delicious, without intermuscular spines, and has high nutritional value. It can be listed all year round, and is deeply loved by farmers, processing plants and consumers at home and abroad, and has a broad prospect for breeding. In recent years, the cultured Penaeus vannamei diseases have occurred frequently, and the risk of breeding has been increasing. In order to avoid the occurrence of d...
