Problems solved by technology

[0003] In recent years, there have been many reports on the success of the monoculture and polyculture experiments of peltago grouse, but the aquaculture diseases such as "split head disease", hemorrhagic edema, spirosponge, and parasitic diseases It is also a trend of high incidence year by year, causing huge losses to farmers
In addition, the price of conventional fish has been sluggish for several years. Affected by this, the risk of adult yellow catfish farming has become prominent, and the confidence of farmers in farming has been severely frustrated. The farming model and industrial structure of yellow catfish need to be adjusted urgently
[0004] Now people tend to breed yellow catfish and freshwater shrimp separately, which not only cannot meet people's various needs, but also wastes water area and feed

Embodiment 1

[0022] A culture method for polyculture of freshwater shrimp and yellow catfish, comprising the following steps:

[0023] 1) Choose a pond with sufficient water source and no silt. The depth of the pond is 1.2m. Set up an insulation shed above the pond, and set up 0.6m high anti-escape facilities around it. Set up 3 water inlets and outlets in the pond, and set up a 40-mesh filter at the inlet and outlet. Drain the water in the pond, remove the natural enemies of fish and shrimp, expose to the sun for 3 days, and obtain an empty pond.

[0024] 2) Pond disinfection treatment: put into 0.7m deep water in the vacant pond that step 1) obtains and drop quicklime disinfection and plant reeds after, the coverage area of ​​reeds accounts for 50% of pond area, hang decomposed microbial organic fertilizer on the pond edge, Place a shelter, adjust the water temperature, dissolved oxygen and pH value of the pond to obtain a cultivation pond; the water temperature of the pond is 25°C, the ...

Abstract

The present invention proposes a mixed-culture method for macrobrachium nipponense and yellow catfishes. The method comprises the following steps: (1) selecting a pond; (2) disinfecting the pond: putting water with a depth of 0.5-1m into the vacant pond obtained in the step (1), throwing quicklime for disinfection, planting aquatic plants, hanging a decomposed microbial organic fertilizer at the edge of the pond, placing a shielding substance, and adjusting a water temperature, a dissolved-oxygen amount and a pH value of the pond to obtain a cultivation pond; (3) throwing fry and young macrobrachium nipponense; and (4) performing feeding management: from a first week to a seventh week, every day performing feeding for 2 times and throwing boiled primary feed; after an eighth week, performing feeding according to the water temperature, throwing traditional Chinese medicine feed, improving the water quality every 3-5 days, and throwing young grass carp and bellamya quadrata. The culturemethod provided by the present invention fully utilizes culture resources, maintains the water quality, improves the immunity of the yellow catfishes, reduces the morbidity rates of the macrobrachiumnipponense and the yellow catfishes, greatly improves the utilization rate of the feed, and increases the yield of aquatic animals.

Description

technical field [0001] The invention belongs to the field of fish and shrimp culture, and in particular relates to a culture method for mixed culture of freshwater shrimp and yellow catfish. Background technique [0002] Green shrimp is one of the freshwater shrimps with high economic value. It grows fast, has large individuals, reproduces quickly, and has strong vitality. It is widely distributed in freshwater lakes in my country. Freshwater prawns are tender and delicious, rich in nutrition, and contain 16.40g of protein per 100g of edible portion. It is an omnivorous aquatic animal, partial eclipse animal feed, artificial breeding is mainly fed with commercial feed. It likes to live in the slow stream where the aquatic plants are overgrown. The habitat water depth varies from 1-2 meters to 6-7 meters. [0003] In recent years, there have been many reports on the success of the monoculture and polyculture experiments of peltago grouse, but the aquaculture diseases such...
