Problems solved by technology

However, due to serious fishing and backward breeding technology, the germplasm resources are degraded and the quality of freshwater shrimp is reduced.
Due to unreasonable breeding and blind expansion of the scale, it did not bring about an increase in quality and economic benefits, but instead led to abnormal hatching, early sexual maturity, and high morbidity of freshwater shrimp.

Embodiment Construction

[0025] Build 200hm 2 The breeding ground is divided into 16 large and small ponds, with a water depth of 1.3m and a slope ratio of 1:3. Standard, pH value is 7~8, and each pond mouth is equipped with two 3kW aerators. The silt is 5-10cm thick, and water peanuts are planted in the shallow water of the pond, with a width of 1.5m. The breeding ground is disinfected and fertilized. The water temperature is above 20°C. The first batch of prawns will be released in early March, with 7,000 juvenile shrimp per mu. Before April, only plant-based feed, including rice bran, will be fed. Wheat flour and bran are fed once every 5 days, and the feeding amount is 1.5% of the total weight of the shrimp body; after April, it is mixed with animal feed crushed snails and small miscellaneous surimi, and it is fed once every 1 day, and the feeding amount is 2% of the total weight of the shrimp body; When the temperature is above 18°C, put in at 10:00 am and 6:00 pm, and the amount of feeding is ...

Abstract

The invention relates to a pollution-free recirculating breeding method for freshwater shrimps, which comprises the following details: after clearing up and sterilizing a culture pond, injecting fresh water and applying fertilizer, and putting juvenile shrimps in the pond to breed, wherein a breeding manner of two batches in one year is adopted, i.e., putting the juvenile shrimps once in March and July in the same year; finishing catching in June and January and clearing up the pond; throwing in feed at regular time and fixed quantity during breeding, and adopting a mixing breeding manner at the second batch. The pollution-free recirculating breeding method for freshwater shrimps can effectively increase the yield and benefit of freshwater shrimps and promote the development of the freshwater shrimp breeding industry.

Description

technical field [0001] The invention relates to a method for circular cultivation of pollution-free freshwater shrimp, in particular to large-scale, pollution-free and large-scale cultivation of freshwater shrimp, which improves yield and increases economic benefits. Background technique [0002] Freshwater prawn, scientific name Macrobrachium japonica, is a freshwater prawn with high economic benefits, belonging to Crustacea, Decapod order, and Shrimp family. It is widely produced in freshwater lakes in my country. It has delicious meat, rich nutrition and high protein content. It is a valuable aquatic product. However, due to serious fishing and backward breeding technology, germplasm resources are degraded and the quality of freshwater shrimp is reduced. Due to unreasonable breeding and blind expansion of the scale, it did not bring about an increase in quality and economic benefits, but instead led to abnormal hatching, early sexual maturity, and high morbidity of fresh...
