Construction of lobster culture site

Lobster has a strong ability to adapt. According to the survey, lakes, rivers, ponds, canals and paddy fields can survive, even in some water bodies where it is difficult for fish to survive. They have a strong tendency to flow, like fresh water, go up against the current, and like to live in groups. They often gather around the intake in the culture pond. Let's take a look at the construction of the lobster breeding site.

Culture environment

Lobster culture sites should choose places with sunny ventilation, quiet environment, sufficient water sources without pollution, rich sources of bait, convenient drainage and irrigation, convenient transportation and power supply, and can use water from rivers, lakes, reservoirs and ponds as water sources. Well water and spring water can also be used, and the PH value of water quality is about 6: 8.

Shrimp pond environment

Lobster culture pond area can be large, small, water depth of 0.6-1.5 meters, the best east-west direction, toward the sun, the pool around a slight slope, flat bottom, slightly inclined to the side of the drain, easy to drain the pool water. The pond must be surrounded by soil slope protection, mainly lobster hole habitat, so that it can survive the winter safely. The ridge is 40cm high and 50cm above the water surface, and the width of the ridge should reach 1m, mainly to prevent lobster from drilling holes and filtering water. if the pond area is more than 10 mu, one or two additional ridges can be built in the pond, which are evenly distributed in fields, wells and crosses, mainly allowing lobsters to drill holes and spawn and reproduce. Lobsters like nocturnal activities and crawl along the ground. Asbestos tiles and plastic films should be used on the periphery of the pool ridges, and wooden piles should be used as supports to build an anti-escape wall with a height of 50 centimeters. the bottom is buried in about 30 centimeters sealed to ensure that no lobsters can escape.

Pool disinfection

The common disinfection method of lobster pond is to use quicklime to disinfect. During disinfection, only 5 centimeters of stagnant water is left in the pool water, and quicklime is evenly sprinkled into water slurry to dissolve. The dosage of quicklime is generally 25 kilograms per mu. On the second day of using quicklime, the bottom of the pool is stirred with iron rakes to fully mix lime slurry and silt. Do not release the disinfected water, stay in the pool, start to enter the water the next day, and reach the required level of feeding. At the same time, the lobster will molt in the process of growth, must take in enough calcium, the calcium content of quicklime is more than 50% (the theoretical value is 71.4%), and the effect is better when the price is low.

Water quality and fertilization

After reaching the required water level, the lobster pond applies organic fertilizer (fermented pig, cow manure, chicken manure and other animal manure), such as water depth of 60 to 120 cm, 250 to 350 kg per mu. After three days, if the pond water is not fat, a small amount of fermented agricultural machinery fertilizer can be sprinkled many times, so that the pond water is gradually transformed into appropriate fertility, so that the transparency of the water is 25cm and 35cm. It is appropriate to use clear green, and plankton is gradually formed in the pond. After five days of disinfection, shrimp can be planted.
