The production of seawater prawn aquaculture is now developing at a rapid pace. It has become a socially industrialized production enterprise. At the same time as the output is increased, people have put forward higher requirements for the environment of the sea and the quality of cultured species, in order to be able to In order to protect the environment and enter the market, the Ningbo Fisheries Research Institute proposed the penetrating intensive intensive aquaculture of Penaeus vannamei in South America. With the strong support of the relevant departments of cities and counties, it will be fostered in the Gaohutang Demonstration Park in Dajiahe Town. The aquaculture area is 70 mu. After 90 days of trial raising, the average body length of the shrimp reaches 11.2 cm per mu and reaches 342 kg. First, aquaculture site selection of a total area of ​​70 acres of aquaculture, including a total of 56.5 acres of shrimp ponds, a total of 13.5 acres of 3 reservoirs, ponds, effective depth of 2.5 meters, each pond is laying plastic film. The entire system is equipped with 80KW transformers and 75KW generator sets, and 0.75KW/mu equipped with aerators. Second, the stocking of shrimp 1. Before stocking preparation 15 to 20 days before the seedlings, into the sea water, with 50PPM bleaching disinfection, the third day after the water treatment Fermented organic fertilizer 15-30Kg / mu, and then Add proper amounts of beneficial algae to cultivate basic baits so that the water is yellow-green or green-brown, and aerators are properly opened. When releasing seedlings, check whether the indicators in the water quality are equivalent to those in the original pool. 2. Fangmiao time: on June 27th, it was purchased from the locality and was tested and confirmed to be virus-free shrimp seedlings 3. Fangmiao specification: 0.8-1CM 4. Fangmiao density: 50,000 yuan/mu 5. Water level: At that time, the water level was 1.5M. III. Rearing and Management 1. After the feed is released, 5-7 days later, press 20-30g/million, input high-quality compound feed, and then increase it by 10% every day. Diligently observe whether there is residual bait and feces in the feed table. Thickness, length. The size of feed pellets is determined according to the length of P. vannamei and the number of feedings is based on the principle of eating less and eating more. 2. Day-to-day management a. Regularly check the indicators of water quality and make records. This is an effective measure for remedying the disease. b. Cultivation period will be tested every month for shrimp pathogens. c. Observe the feeding and utilization of shrimp. d. Observe whether shrimp activities are normal, find sick shrimps and dead shrimps to remove in time, and check the cause of death. 3. Water quality control a. Water quality requirements: During the entire breeding period, it is required to maintain a water level of 2 meters or more, to prevent leakage, to avoid large-scale irrigation, and to add 3 to 5 cm of water each month in the early stage of cultivation. During the middle and late breeding period, the water is harmful and changes according to algae. The single cell overdose and so on need to change the water as appropriate, take a less change and change, change the amount of water in the daily control of 5-10cm zeolite powder, improve the water quality, if fresh water resources, adding fresh water in the latter period is an effective increase in production method. b. The use of growth machine: the oxygen machine's start-up time can be based on dissolved oxygen needs, so that the dissolved oxygen in the water is always maintained at 5mg / l or more, but under normal circumstances, after the seedlings are extended according to the need to extend the boot time. In addition, on the rainy days should increase boot time and frequency. c. Stabilize water quality: Use physical and chemical means and microbiological preparations to regulate water quality. Use water from 15 days after seedling release. Use every 15 days as a use cycle. Adjust lime with quicklime, improve bottoms with water quality improver, degrade with Greenway. The toxicity of metals or toxic substances, especially the frequent use of microbial agents to reduce the concentration of ammonia nitrogen and nitroso nitrogen, maintain stable single-cell algae, and achieve little or no drainage of aquaculture water. d. Disease prevention and management: Disinfect the water body every two weeks (strict use of antibiotics and antibiotics is strictly forbidden). Attention should be paid to the use of microbial agents only after three days. Improve the disease resistance of shrimp while preventing it. That is, the periodic addition of Vc immune polysaccharides and other nutrients to shrimp feed is an effective measure to prevent disease. Fourth, the results 1. Water quality indicators: During the entire period of cultivation, 7 ph cultivated ponds were maintained at 8.0-8.5, with a difference of about 0.3 between morning and evening. The transparency of the early stage is relatively stable at 25-35cm. In the later period, as the feed utilization rate of shrimp decreases, the relative pressure on the water increases, and the transparency drops to 20-30cm. During the breeding period, oxygen-enriched cultivation was promoted, and dissolved oxygen was maintained at 5.0 mg/l or more. 2. The growth of white prawn: The seedlings were released on June 27, and they were arrested one after another on September 19. During the whole growing period, the shrimps grew well. The average body length was 0.8-1.0 cm long and 11.2 cm long. The growth rate was 1.1. Cm, from the growth record, the growth of Penaeus vannamei has obvious seasonal changes with temperature. 3. Collecting results and economic benefits: Starting from September 19th, the catch rate has reached 60%, and the feed coefficient is 1.2. The communist shrimp produced by the 7 ponds are as follows. 5. Analysis and discussion 1 Disinfection treatment: During the whole cultivation period, the out-of-sea water is disinfected through the livestock pond and put into the shrimp pond. By killing aquatic organisms by disinfection, it is possible to isolate external seawater viruses into shrimp ponds. This is one of the key technologies for enclosure-type intensive culture. 2 The density of seedlings: The density of stocking directly determines the amount of economic benefits in the growing process. Too little will affect the yield, and too many specifications will be difficult to increase. During the trial period, shrimps will increase in size as shrimp grows later. As space increases, prawns will be infested after being frightened by clusters in the evening, and they will easily injure shrimp individuals, leading to susceptible bacterial viruses to shrimps. According to the benthic characteristics of prawns, they can add mesh to the water and make full use of the water body space to increase the unit. The body of water loves shrimp production and reduces unnecessary mechanical damage to the shrimp, thereby increasing the survival rate. Secondly, adding mesh can be used as a good concealer for shrimps to prevent mutual disability when prawns are clam shelled. 3Water quality regulation: With the increase of shrimp individuals, the amount of feed increased, the accumulation of organic matter exceeds the speed of organic matter decomposition and mineralization, resulting in an increase of suspended solids in the water, and the water quality is turbid. In this experiment, we used microbial agents, zeolite powder, and other organisms. Physical methods to regulate water quality and achieve better results. During the whole incubation period, the water color was basically stable, and the transparency remained at about 25CM. It was proved that the water quality improver and microbial control technology can change the original microbial groups in the pond and decompose too much organic matter in the water. It is very stable to balance the algae in the water. 4 Harvesting: As the farmers adopt traditional drainage methods to collect shrimp, and do not pay attention to the appropriate water intake after drainage, continuous exchange of water within a few days leads to large areas of shrimp death. It can be seen from Table 1 that shrimp estimated to be dead due to this cause is estimated at 3200 kg. Therefore, it is not appropriate to use conventional drainage for closed intensive aquaculture, and the bottom of the pond should be leveled to use a large area grid or Ordinary net pulled directly from the water, which may avoid unnecessary losses.
