First, the basic situation
From 1994 to 1995, Guangtai Industrial Co., Ltd. and Qianshan State-owned Protective Forest Farm at Dashuiqiao Farm in Xuwen County established the Nanmen shrimp culture base in Xiyang Town, Xuwen County. It has invested more than 1.8 million yuan and developed 92 acres. The high-grade shrimp pond on the surface of the water has been used for the production research of high-density intensive intensive culture technology of the high-density prawn. The high yield has been achieved. In the 95th round of the pond, the yield per mu was 1100 kilos and the average yield was 969 jin.
The high density pond larvae high-density intensive culture technology has opened up a new way for the aquaculture industry, which shows people a new model and brings new hope to the coastal people to get rid of poverty. Its high economic efficiency has attracted the attention of all sectors of society and given a high degree of evaluation.
The model of the South Gate Breeding Base is generating huge social benefits and greatly promotes the development of the aquaculture industry. Now, under the guidance of the strategic thinking of the Municipal Party Committee for the development of the marine economy, the coastal masses formally launched a new upsurge in the development of high-level shrimp ponds for high-density intensive shrimp culture.
Second, experience
To develop high-level ponds for high-density intensive culture of shrimp, the following basic conditions must be met:
(I) More advanced equipment
1, water lifting equipment
The high shrimp ponds rely on water to raise shrimp. Water-supplying equipment mainly includes submersible pumps, axial-flow pumps, self-priming pumps, etc., both domestically and imported. The methods for lifting water include one level of water lifting and two level of water lifting. The water pumping equipment we use is a submersible pump. All of them are made in China, and the water lifting method is a level one.
2, oxygen equipment
Prawns are intensively intensive and must be oxygenated. The function of the aerator is to improve the water quality. Through the water circulation, the content of H2S and ammonia nitrogen in the bottom of the pool is reduced, and the dissolved oxygen in the pool water is increased, so that the shrimp metabolism is vigorous and the growth is rapid. At the same time, it can effectively prevent filamentous algae, fixed ciliates, crustaceans, and organic debris from adhering to shrimps and reduce the occurrence of diseases. Oxygen-increasing equipment is mainly aerators, both domestically and imported, with more models. We have used water-car type domestic aerators, but the effect is poor. Domestic aerators are more suitable for freshwater ponds. However, the effect of seawater shrimp ponds was not very good, and they were later replaced with imported aerators. The manufacturing process, materials, and accessories of imported oxygen aerators are relatively advanced, and the effect of adding cultivation is good. I have one to three 1--2 horsepower aerators per acre.
(B) Quality feed and shrimp
Prawns are intensively intensive and must have high-quality feed and shrimp. During the aquaculture process, we conducted a series of studies on the combination of yield and yield, seedlings and feeds, plankton and water quality, and sediment and disease. Our feed for shrimp farming is entirely made up of Yuehai brand. All shrimps are provided by our own shrimp farms. There are four shrimp farms in Russia.) In the 32-acre round pond. With 30,000 seedlings per acre, the yield rate reached 80%. The average yield per mu was 969 jins, and the bait factor was 1.5-1.8:1. That is, 1.5-1.8 jins of Yuehai brand feed can develop 1 jin of prawn. In the sixty-million-square-meter square shrimp pond, 20,000 seedlings per mu, the harvest rate is over 70%, the yield per mu is 700 kilos, and the feed coefficient is 1.6:1. Among them, there are two shrimp ponds for a breeding period of 4 months. 14 tails/jin. Practice shows that individual shrimps cultured with Yuehai brand feed are uniform, robust and robust, have strong disease resistance, and are full of elasticity. They can satisfy the growth needs of shrimp both in terms of palatability and nutrition, and are also more suitable for high-density intensive culture of shrimp.
(III) Advanced disease prevention and breeding techniques
An urgent problem to be solved in shrimp culture is disease prevention and control. Shrimp disease has been plaguing shrimp farmers, and it has become a deterrent to the development of shrimp aquaculture. The disease prevention of prawn has attracted the attention of all parties in the world. Thailand is the most advanced country in the aquaculture industry in the world. The annual output of cultured shrimp is 220,000 tons, and China is about 6-8 million tons. Thailand's breeding technology, advanced aquaculture equipment, disease prevention technology is more advanced, they produce more than two tons per mu. We, Guangtai Industrial Co., Ltd., have technicians who are returning from Thailand. They have a long time in Thailand and have a close connection with the majority of aquaculture workers in the country. They have a faster grasp of the Thai aquaculture industry (they now have People are in Thailand). Thailand's aquaculture industry also suffered a large area of ​​disease in previous years. After years of research and practice, researchers have gradually explored a set of effective management methods for preventing shrimp disease.
Shrimp high-density intensive culture requires advanced farming techniques. We take a scientific approach to all aspects of the breeding process. Such as the best amount of seedlings, the best amount of feed, the best biomass, the best disease prevention drugs. The best methods for disease prevention have accumulated richer data and gained better experience. In many cases, we held related training sessions to discuss, communicate, and advance together with a large number of aquaculture workers to continuously promote the development of the aquaculture industry.
