Japanese shrimp is widely distributed in the world because of its delicate meat, delicious taste and rich nutrition. It is a popular high-protein, low-fat food. Its wide food, short breeding cycle, low cost of farming, many countries in the world have carried out aquaculture, southern China's Guangdong, Hainan, Fujian are suitable for the cultivation of Japanese shrimp.
Because of its many diseases, most of the places in the world currently use the autumn and winter to release seedlings and do not feed baits, allowing them to grow freely. Therefore, the yield has not been high and the benefits are low. We adopt a new method for shrimp culture in Japan, which has obvious benefits. The main measures are described as follows:
I. Preparation before release
1. Shrimp tank selection Shrimp pool complete without loopholes, the bottom quality is sandy and silty, the water quality requirements fresh and pollution-free.
2. Dredging pumping the bottom of the pool, wash away the sludge.
Second, seed stocking
1. Seeds require health, vitality, and healthy limbs.
2. Seed transport with double plastic bag oxygenation method.
3. Seed stocking selection In the sunny weather from 4 to 6 o'clock in the afternoon, the plastic bag is placed in water until the temperature difference between the inside and outside of the bag is not high enough to put the seedlings into the pool.
Third, daily management
1. The bait is not fed during the first week of feeding and is fed in the second week. The shrimp feed is fed at 8:00 am and 4:00 p.m. and the feed rate is 5% (using spot feeding to observe Its feeding situation).
2. Observing the survival rate From the third week after releasing the seedlings, discharge the electric shock and observe the survival rate to determine whether to replant.
3. Detoxification, control of water quality From the day the feed was started, the water was discharged every two weeks and electric shock was used to promote the clam shells. In addition, 10 ppm of bleaching powder and 5 ppm of quicklime were used to disinfect the water.
4. Disease prevention and control From the third week after the release of the seedlings, bait feeding was started, and 500 g of diet was added with 1 g of vitamin C.
Fourth, harvest the method of electric shock to catch shrimp, catch large stay small.
