Crayfish culture process is standardized. If you want to know or prepare to breed lobster, you should learn it quickly.

Recently, many friends consulted lobster farming related standardization process, in fact, a long time ago has been shared, today the previous article re-edit, if there are unclear friends, you can understand again.

Lobster farming process:

1. Choose the right pond mouth

Lobster breeding must be selected pond site, the general soil to loam for the best, convenient lobster hole and stay water, water intake and drainage convenience, the surrounding as far as possible away from pollution sources.

quicklime disinfection

II. Disinfectant fertilizer water

The newly-built lobster pond must be thoroughly disinfected, otherwise it will be very troublesome in the later stage. We generally choose quicklime for dry pond disinfection. Moreover, the newly dug lobster pond needs fertilizer water and plankton cultivation. There are many related products on the market with uneven effects. Attention should be paid to the selection.

aquatic planting

III. Planting related aquatic plants for lobster farming.

There are many kinds of aquatic plants suitable for lobster farming, such as Elodea, verticillata, bitter grass, Zizania latifolia, etc. You can choose one or more kinds of plants to match, and the coverage of aquatic plants is about 50% of the whole water surface.

IV. Escape Prevention

Lobsters have the habit of escaping upstream and ashore. Purse nets should be built around the pond to prevent escape. At the same time, the width of the dam should be widened to prevent lobsters from breaking through the dam and escaping. The depth of lobster holes varies from 30cm to 100 cm, and the best dam width is about 1.5 m.

Premium shrimp fry

V. Selection and release of shrimp seedlings

Select the right quality shrimp fry for release. Because it involves the survival rate of shrimp seedlings in the later stage, reproductive ability, the size of the finished shrimp, everyone understands the truth of planting melons and beans, the quality of shrimp seedlings is not good, it is easy to cause later breeding failure. However, at present, no company has cultivated new varieties on the market. Some even introduce that their yield per mu can reach several thousand catties. At present, the annual yield of lobster is only seven or eight hundred catties, generally five or six hundred catties, and the difference is two or three hundred catties. So when buying seedlings, keep your eyes open.

VI. Choose the right products for breeding

Carnivorous fish shall not be cultivated in the mixed culture pond, and grass carp and bream which feed on aquatic plants shall not be too much. The varieties that can be mixed culture include silver carp, bighead carp, allogeneic crucian carp, river crab, green shrimp, etc., suitable mixed culture varieties can be selected according to local conditions, comprehensive culture can increase culture income, and moreover, it can effectively evolve water quality. When polyculture, attention should be paid to the release time of shrimp fry and fry, as well as their disease prevention in the breeding process.

VII. Feed delivery

During lobster breeding, breeding friends increase the feed input in order to obtain more harvest and breeding profits. However, when the feed input is greater than the lobster intake, the feed deteriorates in the pond, pollutes the water quality, and causes the lobster to fall ill or grow slowly. The general feed input amount is 6% of the weight of the shrimp stored in the pond. During the growth of the lobster, 11 times of shell removal are required. Therefore, calcium intake also has certain requirements. The clam shell can be ground into powder and mixed into the feed. Drop it together. Lobsters are omnivores. Grass accounts for 80% of lobster food, so the amount of aquatic plants in the pond must be sufficient to purify the water quality and the main source of lobster food.

VIII. Prevention of related diseases

Lobster disease less, generally will not come on, if the disease should be the right medicine, disinfection and sterilization with chlorine dioxide, ciliates and so on with zinc sulfate, banned polyester, organophosphorus drugs. Lobster common diseases are rotten gill disease, black gill disease, rotten tail disease, aggregation worm disease and so on. Quicklime can be applied once a month at a dosage of 20 kg per mu, which can not only improve water quality, but also increase calcium in water and promote lobster shelling.

IX. Water quality conditioning

Water level management should be managed according to the principle of "shallow-deep-shallow-deep" according to seasons and temperature changes, that is, master the principle of "shallow spring and full summer". Moreover, it is necessary to timely replace water. If conditions permit, machines can be added to promote the flow of upper and lower water layers, and the oxygen production of aquatic plants can be fully utilized to improve the oxygen content of water bodies.

X. Timely sales

Our lobster farming generally involves door-to-door purchases and rarely involves logistics transportation. However, if some farming friends are ready to make lobster farming into an industrial chain, they can also continue to pay attention to understanding lobster transportation and preservation. However, no matter which one, we should pay attention to when lobster prices are high and when prices will fall, so that we can timely let lobsters out of the pond for a sale. According to the Chinese lobster research report, Lobsters are generally listed in March and April, and the price is relatively high. However, as lobsters are listed one after another, the price will generally fall in July, August and September. In October, with the decline of lobster production, the price will further increase. Friends of farmers can adjust the time when lobsters come out of the pond appropriately to obtain an optimal sales price.(Note that the premise is to master the relevant technology, otherwise please carefully carry out anti-seasonal sales) Due to space limitation, please click on the author's avatar to communicate, or you can directly search Huai 'an Xueyuan lobster breeding base to learn more about lobster breeding.
