If you want to raise lobsters, how can you raise them well? Where can shrimp fry be served? Technolo

Lobsters are not suitable for long-distance transportation, and it is best to buy them in the surrounding villages. There is a lot of information on online breeding technology, you can check it yourself. But don't believe in any high-yielding seeds, there is no such thing at all.

How to raise shrimp seedlings.

1. Shrimp seedling stocking: 5 100,000 shrimp seedlings per mu, with a size of more than centimeters, and the time should be in June and July.

2. Shrimp stocking: 20 25 kg of shrimp seed per mu, 1000 1600 kg of fish, and the time should be in October and December.

3. Stocking precautions: Shrimp seed stocking should be carried out in cloudy or rainy days, in case of sunny days, it should be carried out in the morning and evening, so as to avoid direct sunlight and affect the survival rate of stocking. Shrimp seed needs to be put enough at one time.

4. Raising silver carp fingerlings: 80 100 silver carp fingerlings per mu of shrimp ponds, with a specification of about 30 kilograms, and silver carp summer fingerlings can also be raised, 200 per mu. Silver carp fingerlings should be stocked 10 to 15 days after shrimp seed stocking to ensure the demand for bait organisms for green shrimp.

Raising silver carp can adjust the water quality, and the second is to make full use of the water body to increase the income of fish.

When is it more appropriate to raise lobster seedlings.

The regular stocking time is usually in November or the end of March of the following year. In the process of lobster farming, juvenile shrimp can grow to commercial specifications in 60 to 90 days under the condition of suitable temperature and sufficient feed. The seedlings are released in March, and the rotation fishing begins around June, and the big ones are sold and the small ones are kept.

Due to the large catch and small retention, round fishing and release, it can improve the recapture rate, sell at a good price, and achieve the purpose of high yield and high efficiency.

Crayfish farming environment requirements:

1. Water temperature. Crayfish is a wide-temperate aquatic animal, its water temperature adaptation range is 0 37 °C, the suitable water temperature for growth is 18 31 °C, the optimal growth water temperature is 22 30 °C, and the water temperature for fertilized egg hatching and larval development is 24 28 °C. When the water temperature drops below 10°C, the crayfish stop feeding and burrow into the burrows to overwinter.

In summer, when the water temperature exceeds 35°C, the feeding intake of crayfish decreases, and in the natural environment, it will burrow at the bottom of the burrow at the low temperature. Prolonged high temperatures can lead to death, so shade and cooling measures should be taken.

2. Dissolved oxygen. Maintaining a certain degree of phytoplankton in the shrimp pond has a greater effect on improving the dissolved oxygen in the water body. The gills in the cuirass of the crayfish head are very developed, as long as they are kept moist, they can breathe, they have a strong ability to use the oxygen in the air, and the short-term lack of oxygen in the aquaculture water body generally does not lead to the death of the crayfish.

Therefore, the survival of crayfish does not require as much dissolved oxygen in the water as other fish, but the growth requirements are higher, and the dissolved oxygen content of the water body should be kept above 3 milliliters in order for crayfish to grow normally.

3. Organic matter.

The presence of organic matter in the water has a positive effect on crayfish, and the appropriate oxygen consumption of organic matter is 20-40 mg liters; If it exceeds 50 milliliters, it will be harmful to the crayfish, at this time, it should be replaced with new water to improve the water quality.

4. Control of hazardous substances.

There are two types of toxic substances in aquaculture waters: one is caused by external pollution, and the other is the poisons generated and accumulated by the imbalance of the internal material circulation of the water body, such as hydrogen sulfide and nitrogen-containing substances such as ammonia and nitrite.

5. Soil and sediment.

The soil used to build the shrimp pond is loam or clay, which is not easy to seep water, can retain water and save energy, and is also conducive to crayfish digging burrows and avoiding the use of sand. Crayfish live benthically, and too much or too little silt will affect their growth. Too much silt and a large amount of oxygen consumption in organic matter make the bottom water lack oxygen for a long time, which is easy to lead to diseases; If there is too little silt, it will not play the role of fertilizer supply, fertilizer preservation, bait and water quality improvement.

Generally speaking, the thickness of the silt at the bottom of the pond is maintained at 15 to 20 cm, which is conducive to the healthy growth of crayfish.

1. Stocking shrimp seedlings: Stocking shrimp seedlings should be stocked with 6000-8000 juvenile shrimp with a length of 2 cm or 4000-6000 juvenile shrimp with a length of 3-5 cm per mu in the morning and evening of sunny days. The specifications of shrimp seedlings stocked in the same pond are neat and consistent.

At the same time, about 50 grams of flowers, 300-400 silver carp and 200 bream can be stocked in the pond water.

2. Careful bait: within 3 days after the seedling, put the minced small fish and minced meat, and put the small trash fish, the lower foot minced meat or compound feed within 1 month after 3 days, and when the shrimp seedlings grow to 6-7 cm, they can all be fed with crushed snails, mussels and an appropriate amount of plant feed such as wheat, bran, corn, cake meal, etc. or compound feed. The daily feeding amount is based on full, eating, leaving no residual bait, generally medium and small crayfish are fed according to 15%-20% of body weight, and adult shrimp are fed according to 5%-10% of body weight, which can be adjusted according to the eating situation of shrimp.

Feed 2 times a day, once in the morning and once in the evening, the amount of feeding at night accounts for 70%-80% of the daily feeding amount, the bait should be cast around the pond, and appropriately dispersed, and the lobster is concentrated in the place where it is appropriately cast more, in order to facilitate its feeding.

3. Water quality management: lobster grows fast, has a strong metabolism and large oxygen consumption, so the water quality of the shrimp pond should be kept fresh, add water 15-20 cm deep every week to ensure that the water quality is fresh and clean, and there is enough dissolved oxygen, and the transparency of the pool water is controlled above 35 cm deep. Strictly prevent water quality from industrial pollution, pesticide pollution and chemical pollution.

When the dissolved oxygen in the water is low, the water quality is aging, or in case of thundershowers, hot days, cloudy days and other bad weather, the amount of bait should be reduced or stopped, and pay attention to observation, if the lobster is found to be slow to react, swim to the shore, float and climb to the shore, it means that the lack of oxygen is serious, and it is necessary to inject water or open an aerator to increase oxygen in time.
