First of all, you should choose a standard pond to raise shrimp. Then, the requirements of the pond should be defined according to the proportion of Penaeus vannamei culture, and the depth can be about1.8m. The pond should be convenient for water intake and drainage to ensure adequate water supply, and the shrimp culture should have good water quality to maintain nutritional needs. In daily aquaculture, the pond water quality should be sprinkled with wine mixed culture bacteria to enhance the vitality of the water body.
1. The swimming pool shall be equipped with an oxygen increasing device to supply oxygen to the swimming pool within the specified time every day to ensure sufficient dissolved oxygen in the swimming pool.
2. Shrimp seedlings must be disinfected before stocking. Quicklime can be added to the pond about 25 days before shrimp larvae are stocked. After disinfection with quicklime, it is necessary to add appropriate concentration of bleaching powder to the pond one week in advance, and also need to add appropriate fertilizer, such as chicken manure.
Second, shrimp management
1. It is also important to choose high-quality shrimp seedlings. Because Penaeus vannamei is farmed in greenhouse, all shrimp varieties that have been desalinated are selected. In addition, according to the breeding conditions of greenhouse ponds, shrimp species that can adapt to the environment of greenhouse ponds should be selected, and shrimp seedlings that are sold in the market should be selected as much as possible.
2. After the non-toxic test, the shrimp seedlings can be guaranteed to meet the specified requirements, and the shrimp seedlings can be prevented from being infected with viruses.
Third, the preparation work before stocking
1. Before stocking, put the bag with shrimp fry in the pond for about 15 minutes to make the shrimp fry in the bag adapt to the water temperature and basic environment of the pond. After they adapt, they will be unpacked and put into the pond in batches, which can reduce the stress reaction of shrimp larvae and avoid a large number of deaths due to the inadaptability of shrimp.
2. The number of shrimps must match the pond area. Generally, you can put a fixed grid in the pond, and then put a fixed number of shrimp seedlings in each grid to avoid the random movement of shrimp seedlings.
Fourth, feeding management.
1. According to the growth of prawns, reasonable feeding can ensure that the amount of feed fed can meet the growth needs of prawns. In order to accelerate the growth of prawns, high-dimensional vitamins can be used to supplement prawns, so as to enhance resistance, promote growth and development, improve palatability, reduce the occurrence of various stresses, enhance group vitality and improve feed conversion rate.
2. Master the diet rules of prawns, meet the feeding habits of prawns on time every day, avoid feed waste and reduce the impact of excessive bait on the water quality of ponds.
Verb (abbreviation for verb) regulates water quality.
1. According to the change of water quality, the water quality must be adjusted in time. Splashing Vibrio in the water can effectively regulate the water quality of the pond and carry out running water. The water temperature can be adjusted according to the season. When the water temperature changes, corresponding measures must be taken to stabilize the water temperature to avoid the influence of the water temperature on the growth of prawns.
Prevention and treatment of intransitive verb diseases
In the process of shrimp culture, water must be changed regularly to ensure clean water quality. When the dissolved oxygen in the water is insufficient, the aeration equipment should be turned on in time to increase oxygen to ensure that the shrimp has enough oxygen to grow. In addition, it is necessary to control the transparency and pH value of water, reduce the change of pH value, and prevent the excessive change of pH value from affecting the growth of shrimp. According to the growth of shrimp seedlings, the prevention and control level of shrimp seedling diseases can be improved. Feeding vino compound probiotics can enhance the growth of intestinal beneficial bacteria, improve digestion and absorption rate, reduce intestinal burden, give full play to intestinal function, increase food intake, help growth, improve resistance, reduce the occurrence of enteritis, diarrhea and feed feces, and improve reproduction rate and uniformity.
