Common misunderstandings in lobster culture

In recent years, the "craze for lobster culture" is also heating up year by year, but most employees are influenced by traditional concepts such as "lobster culture" because they can not correctly grasp the culture technology. Ignoring the correct management of water quality, culture environment, feeding, disease control and other aspects in the culture process, leading to the failure of most culture.

Misunderstanding of output

The yield per mu of lobster is closely related to stocking density, culture environment, feeding amount, disease control and so on. Usually from April to May, there are about 15 seedlings per kilogram per mu, 60 kilograms per kilogram, and the output of the year is about 450 kilograms. The annual output is about 450 kilograms per mu. Exaggerate too much than this output, remind everyone to pay attention! Be careful to be fooled! The amount of input can be increased appropriately if the culture environment is good.

Seedling misunderstanding

The crayfish we are talking about are all crayfish or Japanese crayfish, and they are all of the same breed. The so-called "hybrid breed" is still in the experimental stage and cannot be trusted. The only difference is between trained seedlings and natural seedlings. Artificially propagated seedlings stay in the laboratory stage because of the high cost and the abundant and cheap natural seedlings at present. It is said that artificial seedlings can not be trusted! After training, the general survival rate of seedlings is about 85%, and the survival rate of natural seedlings is not higher than 60%, and it is also related to the water area. It is generally recommended to choose seedlings in the same water area, the survival rate can be guaranteed!

Misunderstanding of culture environment

Select a pond with a good water source, the coverage of aquatic plants in the pond should be 30%, preferably a mixture of floating aquatic plants (such as water peanuts, etc.) and bottom aquatic plants (such as withered grass, etc.). The transparency of the water body is about 30 centimeters. The idea that lobsters can be raised in both good and bad water is incorrect!

Feed misunderstanding

Although the lobster is omnivorous, whether its growth is good or not depends on the intake of protein. It can be fed mainly with fresh miscellaneous fish and field snails, supplemented by plant bait, or fed with compound feed with a protein content of not less than 32%. Rotten animal and plant feed is not suitable for feeding, because of its low utilization rate and easy to deteriorate the water quality, and should not be fed!

Misunderstanding of disease prevention and control

If breeding is to be successful, disease control is also very important. We must get out of the misunderstanding that "lobsters will not get sick" and disinfect them regularly. If the PH value in the water is less than 7, every 15 minutes, the quicklime with the final concentration of 20 grams per cubic meter of water should be pulped and sprinkled evenly. In general, the pond is disinfected with medicine every 15 seconds for 20 days, and molting growth stimulating hormone is added to the feed every 15 days or so for three consecutive days.
