Culture method of base shrimp freshwater culture technology of base shrimp

Kei Wai shrimp is a delicacy that we are all familiar with. We have the opportunity to eat it everywhere in life, not only because of its delicacy, but also because of its high production. We can eat it at any time. Kei Wai shrimp is a kind of freshwater breeding and seawater enclosure culture shrimp, how to cultivate it? What should we pay attention to in the process of raising?

The Culture method of Kei Wai Shrimp

1. Shrimp seedling desalination: the key to the success of Jiwei shrimp desalination culture lies in the desalination of shrimp seedlings. Seedling manufacturers should step by step in the process of desalination, and surprise desalination is strictly prohibited. Shrimp seedlings must be desalinated to 1.003 of salt content before they can be directly cultured in fresh water.

2. After the shrimp seedlings enter the pond, it is the daily management work. During the breeding period, in addition to strengthening safety production measures, the main work is water quality management, bait management, disease prevention and so on.

3. Feeding: shrimp seedlings mainly feed on plankton in rice fields one month after entering the pond, grow to 2~3cm a month later, and feed mainly with fine artificial particles (shrimp bait). The daily feeding amount is 50.6% of shrimp body weight; for example, when the water temperature reaches 24030 ℃, the daily feed intake of prawns is increased to 80.010%. Throw 3-4 times a day, bait once in the evening accounts for 40% of the day, conditional places from external waste pits or rice fields to get plankton and wild miscellaneous fish as auxiliary feed.

Technology of culturing prawns in fresh water

1. The suitable area of the pond is 0.13 ha ~ 0.2 ha and the depth is 1.5 m ~ 2 m. The bottom of the pool is flat, with about 10 cm of silt at the bottom, and ring trenches are dug around, 4 meters wide and 0.5 meters deep. HDPE geomembrane can be selected to prevent seepage at the bottom of the pool. The pond has sufficient water source, fresh water quality and no pollution, and has an independent intake and drainage system.

2. Before the shrimp fry is released, the pond should do a good job of cleaning and disinfecting the pond and get rid of other enemy organisms of wild miscellaneous fish and shrimp. About 20 days before stocking, 100 kg ~ 150 kg quicklime per mu of water surface was sprinkled and disinfected in the whole pond; 7 days before stocking, 150 kg of mature and fermented organic fertilizer (mainly livestock and poultry manure) was put on the mu surface, and then water was injected 50 cm deep.

3. During water injection, the water injection outlet was filtered with 40-mesh silk mesh to prevent the enemy organisms of shrimp from entering the shrimp pond. about 7 days later, a large number of copepods and rotifers and other zooplankton appeared in the pond, which was the best time for shrimp seedlings to go down to the pond.

What's the difference between shrimp and Kei Wai shrimp?

1. Because prawns belong to sand shrimp, also known as Kewei shrimp, because wild prawns like to live in sand and low-salt shallow waters, they are used to hiding their bodies in the seabed, protruding only their eyes and the front end of their heads to breathe, used to escape the enemy and wait for food, and crawl into some slow-flowing inner bays at high tide.

2. The shell of shrimp is hard, with obvious yellow-red stripes, small, crisp and sweet, and there is no thorn on the forehead (shrimp gun). The appearance of shrimp is similar to that of spot shrimp, but it is fat, has thorns on the forehead, and the tissue of shrimp is hard. the taste is not as good as that of Kewei shrimp and has no sweet taste.

3. New prawns are commonly known as sesame shrimp and Jiwei shrimp, and there are more folk prawns called Jiwei shrimp. Ji Wei shrimp is a kind of freshwater breeding and seawater enclosure culture, which gets its name from "enclosure culture". The shape of Ji Wei shrimp is like that of prawn, but its shell is softer than that of shrimp, and its shape is not as large as that of prawn, which is generally the size of the middle finger. The yield in the estuarine area along the coast of Guangdong is higher, and its fat shell is thin and its meat is delicious and refreshing.

The Culture Prospect of Kei Wai Shrimp

First of all, I would like to give you some simple figures here, so that you can have an objective understanding of this income and expenditure. Take one mu as an example, the cost from land lease to repair to suitable breeding is about 20,000 yuan, plus the later feed input is also about 20,000, which adds up to a cost of about 40,000. The output per mu is about 2000 jin, and the average price is 30 yuan / jin. The net profit is about 2000-20000-20000-20000 yuan, and the total profit is about 15000 after some losses plus indirect sales. In terms of the current overall trend, the price of Kei Wai shrimp shows a steady rise. First, the price of prawns in Kei Wai is slowly becoming more and more popular. more and more people can afford it, and the demand is on the rise.

Kei Wai shrimp is basically like shrimp in shape, but its shell is softer than that of shrimp, and it has a thin fat shell and delicious meat. Kei Wai shrimp is so delicious that it is an irresistible delicacy for foodie. At the same time, it is a good business opportunity for people in the aquaculture industry.
