How to build a lobster pond and how to raise a crayfish cement pond

Lobster does not have strict requirements for pond conditions, so it is advisable to choose a place with ventilation and sunshine, soil quality and water retention, and no pollution of water sources to build the pond. The size of the pond is 3333 6667 (5 10 acres), and the water depth reaches above.

The bottom of the sand and mud and the bottom are flat, and the slope ratio of the pond and dam is 1:3 4, which has convenient inlet and drainage conditions and anti-theft protection measures As a hidden habitat for lobsters, some aquatic plants can be planted in the pond or a certain number of stones, bricks, tiles and other shelters can be put in.

Before stocking, the pond is cleaned and disinfected with quicklime to kill harmful fish and harmful aquatic insects in the pond and avoid enemy invasion. After 3 days of disinfection, water will be fed, and 10 days later, rich plankton will be cultivated with fermented and rotted organic fertilizer to provide sufficient bait for shrimp seedlings.

a) Breeding facilities.

Existing giant river prawn hatcheries or shrimp hatcheries with sufficient fresh water** can be slightly modified for freshwater crayfish breeding; It is also possible to build a special crayfish breeding farm. Whether it is a renovation or a new breeding farm, it is necessary to consider:

1. Site selection.

The breeding site should be determined according to the scale of production, requiring sufficient water sources, good water quality, convenient drainage and irrigation, fresh air, quiet environment, free from natural and man-made interference, and realizing "three links" (access, electricity, communication).

2. Pool construction.

Breeding facilities need to be built with the following types of pools:

1) Broodstock ponds. For breeding and stockpiling broodstock, the general area of each pond is 60 80 square meters, large-scale production, the area can be hundreds of square meters, the water body is large, the water quality is more stable, and the cultivation effect is also good.

2) Spawning pools. Each pond area is 30 60 square meters, as broodstock spawning and fertilization, to facilitate drainage and irrigation, is conducive to the detection of shrimp holding eggs.

3) Incubation and nursery ponds. It should be smaller, with an area of 4 6 square meters per pool, which is convenient for water exchange, inspection and management, and hatching seedlings in batches.

4) Feed pools. Each pond has an area of 20 30 square meters and is used for the cultivation of small zooplankton.

3. Construction requirements.

Above the depth of the pool, install adjustable drainage pipes, and install anti-escape facilities. The bottom of the pool is preferably sandy loam, or the cement bottom is covered with 10 15 cm thick medium sand. The pool wall is plastered with cement outside the brickwork, and the eaves on the top of the bank are out to prevent escape.

The frame is embedded in the pool, which is convenient for laying the shade net into a plastic film shed. At the bottom of the pond, there are enough bamboo tubes and tile pipes for the shrimp to hide, and several bamboo chips are set up to double as a feed table. The water surface of the pond is 1 3 to cultivate water floating lotus, and some aquatic plants are planted at the bottom of the pond as much as possible.

The water surface of the pond should not be too large, the suitable water surface is 1 2 acres, the water depth is 1 meter, and it has a perfect drainage system and aeration system; The bottom of the pond has a slight slope, no leakage, and repair the anti-escape facilities, before stocking must clear the pond (dry method) to remove debris, weeds, so as not to leave enemies and pathogens in the pond.

Shrimp seedlings put in the pond for 30 minutes after the start of feeding, the early stage to feed cooked soybean pulp, and then add a small amount of small trash fish and snail meat, etc., the feeding amount of shrimp weight 6 8%, divided into morning and evening two feeding.

According to the feeding habits, the total amount of the day in the evening is about 2 3, and the combination of fixed points and pond sprinkling is adopted. In the middle stage, the water temperature is high, the feeding is vigorous, and the feeding amount is 10%. In the later stage, shrimp bait can also be fed with 25% of compound feed such as miscellaneous fish, soybean meal, wheat bran, green vegetables, etc., and the daily feeding amount changes with the water temperature, which is flexible to master.

1. In the place where the water front source is sufficient and the water quality is good, and the terrain is flat and ventilated to the sun, the bottom of the pond is best with loam, and the slope ratio in the pond is about 1:2.

2. There should be a small soil stalk in the pond for crayfish to make a hole to perch, the pond should ensure that irrigation and drainage are convenient, in order to prevent crayfish from escaping, a fence should be built around the pond, and at the same time, there should be a road for farmers to throw feed and small trucks to enter and exit. ”

<> take freshwater crayfish pond aquaculture as an example: it is generally recommended to build ponds in places with sufficient water sources, good water quality, and convenient drainage and irrigation, and ponds must not be built in sandy or soft places. The size of the pond is generally 5-10 acres, the water depth, the width of the pond stem is above, and there is a certain slope.

The pool should be set up in shallow water and deep water areas, as well as inlet and drainage facilities, a large circular mound can be built in the pond for crayfish to burrow, feed, perch, and at the same time some aquatic plants can be planted in the water. It can also be surrounded by asbestos tiles or calcium-plastic panels to prevent crayfish from escaping.

1. Pond aquaculture

1. Freshwater lobster does not have strict requirements for pond conditions, but it is best to choose a place with sufficient water source, good water quality, and convenient drainage and irrigation to build a pond, and it is better to have a continuous pond. The environment around the pool should be relatively quiet. Because freshwater crayfish have the habit of digging burrows and burrowing, they must not build ponds in sandy or soft places.

2. The size of the pond is generally 5-10 acres and the water depth is 5-10 acres. If the pond itself is too large and needs to be divided, then a pond ridge should be added every 20m or so in the middle of the pond. The width of the pond stem is above, and there is a certain slope of the positive swimming.

3. The pond should be equipped with inlet and drainage and anti-escape facilities, and it can generally be surrounded by asbestos tiles or calcium-plastic boards to prevent crayfish from escaping. In order to prevent small trash fish from mixing, it can be filtered with a 60-mesh screen when entering the water.

4. Shallow water area and deep water area are set up in the pool, the shallow water area accounts for about 2 3, and the water level of the deep water area can reach above. A large circular mound can be built in the pond for crayfish to burrow, forage and perch.

5. Aquatic plants should be planted horizontally in the water, which not only provides bait for crayfish, but also serves as a place for crayfish to live, and can also play a role in improving water quality.

2. Rice farming

1. Select fields with good water quality, strong water retention capacity, no pollution, sufficient water sources, convenient drainage and irrigation, water circuit tee, and not flooded for rice and shrimp farming. Pay attention to the ridges that can be used for harvesters, small trucks, etc. to enter and exit, and platforms for farmers to feed feed.

2. Build an anti-escape wall with plastic film, cement board, asbestos tile or calcium-plastic board around the field, bury the base into the soil about 10-15cm, and the top is about 50cm higher than the ridge, and use a wooden stick or bamboo pole every other day to support the stable anti-escape fence, which is required to be perpendicular to the ridge, and the bend can be made into an arc.

3. Shrimp ditch should be excavated along the inner side of the ridge of the paddy field, the width of the ditch is 1m, the field area is larger, and the field ditch should be excavated in the middle of the field, the field ditch is 1m wide and deep, and the area of the shrimp ditch and the field ditch accounts for about 20% of the total area of the paddy field.

4. The width of the ridge is more than 3m, and the height of the ridge is 1m. At 1m away from the ridge, a high pile is drilled every 3m, erected with bamboo, and melons, beans, gourds, etc. are planted on the edge of the ridge, and after the vines are put on the shelf, they play the role of shading and sheltering from the heat in the hot summer.

5. In the shrimp ditch and the field, it is necessary to transplant submerged plants such as bitter grass, black algae and goldfish algae, and the coverage of aquatic weeds should be 30%, and it is better to be sporadic and scattered, which is conducive to the smooth flow of water in the shrimp ditch without blockage.

Summary. Hello (do you need to pour the farmed lobster pond) No, you don't.

The area is not limited, it can be large or small, the water depth is about meters, and the slope ratio is 1 3. The bottom of the pond is required to be flat, the bottom quality is loam, the soil of the pond slope is hard, the pond has good water retention, and the water level is easy to control. The water source requires fresh water quality, sufficient dissolved oxygen, and no pollution.

When rushing into the pool with new water, it should be filtered with 20-40 mesh gauze to prevent wild trash fish and fish eggs from entering the pool with the current. In accordance with the requirements of high irrigation and low drainage, build drainage channels to ensure that irrigation can be carried out and discharged. Lobsters have a strong ability to escape, so it is necessary to do a good job in the construction of anti-escape facilities.

Usually use plastic film, calcium-plastic board or cement board to erect anti-escape facilities along the ridge of the pond to avoid the entry of predatory organisms and the escape of lobsters, and at the same time set up a certain number of mesh, bamboo tubes, plastic tubes and other artificial concealments at the bottom of the pond for lobsters to inhabit, molt and conceal, and reduce lobster burrowing.
