Is there any farmed nine section shrimp, and the difference between farmed nine section shrimp and w

Freshwater aquaculture is not recommended for the nine-node shrimp (Penaeus monodon).

Breeding pond treatment: 70-100kg of quicklime is used per mu of pond to sprinkle at the bottom of the pond, and then water is added 15 days before the seedlings are released, tea meal and chlorine-containing disinfectant are used for treatment, and wastewater is carried out after 2 days. Water Quality Requirements:

The water level is 80-100cm, the transparency is between 20-30cm, and the salinity is between 25-35, and it shall not be less than 18. Can nine-node shrimp be cultivated in freshwater, and it is not recommended to use freshwater aquaculture for nine-node shrimp (Penaeus monodon).

The breeding technology is as follows: the aquaculture pond is treated with seawater to flush the aquaculture pond, the silt in the pond is washed clean, and then the water in the aquaculture pond is emptied and exposed to the sun. If the pond cannot be cleared, use 70-100kg of quicklime per mu of pond to evenly sprinkle on the bottom of the pond.

About 15 days before the seedling, add 80-100cm of water, and then use tea meal to kill the trash fish in the breeding pond, and then use chlorine-containing disinfectant to disinfect (effective chlorine concentration 5-10mg l). After 2 days, fertilize and water to cultivate the base bait. The water quality requires the water level to be about 80-100cm, the transparency to be about 20-30cm, and the water color to be yellow-green.

pH is controlled between, salinity is controlled between 25-35, not less than 18, and the salinity difference with the nursery pond should not exceed 5. The water temperature is controlled at around 24-28.

Stocking is about 4000-6000 per mu, and if the breeding conditions are good, it can be increased to more than 10000. Shrimp seedlings are required to be more than 1cm in length, vigorous, neat in size, robust individuals, no damage to the appearance, no parasitism, 7-9 o'clock in the morning or evening, in the upwind of the shrimp pond seedlings.

It can be raised, but it is difficult to get.

As long as you can eat and sell for money, there will be people who breed it!

There are some differences between the farmed nine-section shrimp and the nine-section shrimp of the wild year, which are mainly manifested in the following aspects:

The growing environment is different: the farmed nine-node shrimp grows in artificial facilities, usually aquariums, plastic ponds, etc., and the growth environment is artificially controlled. Whereas, the wild nine-knot shrimp grows in the natural environment, usually in freshwater waters such as rivers and lakes.

The feeding method is different: the farmed nine-node shrimp are usually artificially fed, mainly artificial feed or other food, and the growth rate is relatively fast. On the other hand, the wild nine-knot shrimp is mainly based on natural food, such as small aquatic animals and plants, and the growth rate is slower.

Different taste and texture: Due to the different growth environment and feeding methods of farmed shrimp, the nutrients, texture and taste contained in the body are slightly different from those of wild shrimp.

**Different: The amount of hail produced by the farmed nine-section shrimp is relatively large and the market is relatively low. However, the production of wild nine-section shrimp is small, and it is affected by environmental pollution and other factors, and the production is relatively high.

It is important to note that whether you are farming or wild shrimp, you need to choose a fresh, odorless product and handle the ingredients according to the correct cooking method to ensure that it is safe and nutritious.

The adaptation to salinity ranges from 5 to 25, and the closer to 10 the faster it grows. The suitable temperature range is 14 34, the optimal water temperature for growth is 25 30, stop feeding when the water temperature is below 18, and the water temperature will not die as long as it is not lower than 12.

It likes to inhabit sand and mud or muddy substrates, generally does not move during the day, has the strongest appetite in the evening, and begins frequent foraging activities. It is omnivorous, and the requirement for feed protein is 35% to 40%, and shellfish, trash fish, shrimp, peanut bran, wheat bran, etc. can be eaten. Penaeus monodon caught in natural sea areas can reach a maximum body length of 33 cm and weigh up to 500 grams to 600 grams.

Shrimp seedlings are cultured in ponds for 80 days and 100 days, with a body length of up to 12 cm 13 cm, an average daily growth of cm cm and a weight of about 25 grams. Each kilogram of shrimp can reach 40 60, the general yield per mu is 100 kg 200 kg, and two crops can be raised in 1 year.
