How many shrimp seedlings should be put in one mu of land? how much do you feed shrimp seedlings in a day?

Shrimp is a very delicious food, and it is rich in calcium and protein, and its nutritional value is very high. With the increasing demand for shrimp, wild shrimp can no longer meet our needs. Shrimp farming has also become one of the most popular projects. So do you know how many shrimp fry can be put in an acre of land? Let's learn about the culture technology of shrimp seedlings together with Xiaobian.

How many shrimp seedlings should be put in one mu of land?

First, double-season culture: before the end of February, autumn propagated shrimp species (specification 1000-1600 / kg) are released per mu, and dry ponds are harvested from June to July. After cleaning the dry ponds, 3.5-45000 larvae (or 0.75-1.0kg) are released per mu.

(2) one-time planting and annual culture (choose one):

1. Stocking shrimp fry with a size of more than 1.5 cm for every 50,000 to 60,000 shrimp fry, suitable for June to July

2. Stocking shrimp species, 20-25 kg per mu, 1000-1600 tails / kg, suitable for December-February

3. Release egg-holding shrimp and put 2-3 kg of egg-holding shrimp per mu.

100000 how much do you feed shrimp seedlings a day?

The main results are as follows: 1. The body length of Penaeus vannamei is 1.0ml 2.5cm, and the feeding amount of 100000 shrimp fry is 300ml 2000g.

2. The body length of Penaeus vannamei is 2.5ml 4.5cm, and the feeding amount of 100000 shrimp fry is 2000ml 8400g.

3. The body length of prawns is 4.5ml 7.0cm, and the feeding amount of 100000 shrimp fry is 8400ml 13500g.

4. The body length of Penaeus vannamei is 7.0ml 9.5cm, and the feeding amount of 100000 shrimp fry is 27000ml 43600g.

Culture techniques of freshwater lobster

1. Aquaculture facilities: the area of freshwater lobster pond is 4 mu, the depth is 1 mu, the depth is 1 mu, the bottom is flat, the bottom is good with loam, the water level is easy to control, the water source is sufficient, and the water quality is pollution-free. At the same time, do a good job in the construction of escape prevention facilities.

2. Pond cleaning and disinfection: drain the pool water 20-30 days before stocking, remove too much silt, renovate the pool ridge, use 75 kilograms of quicklime per mu or bleach powder, bleach powder and other drugs, thoroughly clear the pool for disinfection.

3. Adequate basic fertilizer: 500 kg of rotten livestock and poultry manure per mu was applied to freshwater lobster ponds to cultivate rotifers, Cladocera and copepod plankton to provide palatable bait for shrimp seedlings.

4. Planting aquatic plants: aquatic plants such as verticillium verticillata, Elaeagnus angustifolia and so on are planted in freshwater lobster ponds, accounting for 2% of the area of shrimp ponds. At the same time, nets or bamboo tubes and plastic tubes are set up to provide habitat, molting and concealment.

5. Shrimp fry restocking

① summer stocking: the stocking time is about the middle and last ten days of July, mainly the first batch of young shrimp hatched in the same year, with the size of more than 0.8cm, about 30,000 to 40,000 per mu.

② autumn stocking: the stocking time is from the middle of August to September, mainly the large size shrimp fry cultivated in that year, 25000 ~ 30000 per mu of 1.2cm and 1.5000 ~ 20000 of 2.5cm / mu.

③ winter and spring stocking: the stocking time is in December or March to April of the following year, mainly in the year of stocking that does not meet the market specifications, with a specification of 100,200 shrimp per kilogram and 15000 ~ 20 000 shrimp per mu.

6. Feed selection: freshwater lobster is omnivorous, animal feed includes small fish chips, dried fish meal, snail clam meat and various animal offal, etc. Plant feed includes rapeseed cake, soybean meal, wheat bran, wheat, corn, pumpkin and all kinds of vegetables and upland grass.

7. Feed: freshwater lobsters are mostly active and foraging at night, feeding once at 10: 00 in the morning and 4: 00 in the afternoon. The amount of feed in the afternoon accounts for about 70% of the total daily feed. The daily feeding amount can be increased or decreased appropriately according to the weather, water quality and shrimp activities.

How much does it cost to raise lobster?

The investment cost of raising lobster is relatively low. Generally, about 40 jin of seedlings are needed per mu, and about 1530 yuan per jin, then the cost of seedlings is about 600,1200 yuan. Lobster feed is mainly small fish chips, dried fish meal, clam meat, a variety of animal offal, rapeseed cake, soybean meal, wheat, corn, a variety of vegetables and water grass, etc., the price is very low. In addition, crayfish also need to prepare anti-escape nets, disinfectants, aerators and other supporting facilities.

The above is the summary of shrimp culture technology for you. I hope it can help you. Although raising shrimp does have certain prospects and benefits, starting a business is risky, so you can't blindly follow suit and start a business.
