There is a big gap in the market for mud shrimp now. How much is the profit per acre of mud shrimp farming?

In addition to the white shrimp, there is another kind of shrimp (Penaeus monodon), which has won the trust of many farmers in the past two years. The reason is that many farmers have reaped a lot of rewards after switching to Penaeus monodon, and some farmers have finally won a battle of "turning over" by breeding Penaeus monodon. These are the reasons why this kind of shrimp is becoming more and more popular. It is necessary to dig a pond so that the water depth of the pond reaches 2 meters, tilting towards the outlet, and the proportion is reduced to 0.2%. A layer of plastic anti-seepage film is laid on the bottom of the pond, with an area of ​​10 mu, 1,300 yuan per mu, and a price of 13,000 yuan. There are one or three doors at the inlet and outlet: outer coarse filter, middle door, inner cone filter, costing 1,200 yuan. The total cost of the site is 14,300 yuan.

The configuration of hardware facilities such as water pumps, water inlet and outlet pipes, aeration equipment, cables, etc., water truck aerator: each 1.5kw aerator costs 2,000 yuan, which can be used for 5-7mu high-density intensive shrimp ponds, 2 aerators, a total of 4,000 yuan, and the total cost of two diesel pumps is about 6,000 yuan. The main inlet and outlet pipes cost about 200 yuan. The equipment requires a total of 11,000 yuan. In the first 20-30 days of feeding the young shrimp, spray 20-30 cm deep water, fill the pond with 1-2 kg of quicklime or bleaching powder containing 25-32% effective chlorine and 50 ppm per cubic meter, sterilize and disinfect, dry it after 2 days, and feed water with 80-100 mesh nets, and the water depth is about 60-80 cm. A total of about 3 kg of quicklime is consumed, 200-600 yuan per ton.

Fertilizers should be applied immediately after the pond is filled with water. The fertilization method should be based on a nitrogen-phosphorus ratio of 5: 1, with 1-2 kg of nitrogen applied per mu, and then once every 2-3 days, with half the amount of the previous time. Chicken manure and quicklime are mixed and fermented, and then the chicken manure is hung on the pond wall by the sling method to prolong the fertilizer effect. According to the standard of 15-20 kg/mu, the new shrimp pond is used for dry fermentation of chicken manure. After 7-10 days of cultivation, the shrimp fry is injected with transparent water, and the color is about 30-50 cm, brown, yellow-brown or green. The total cost of fertilization is about 500 yuan. The yield of shrimp fry per mu is 100,000, and the price of pollution-free shrimp fry is about 180,000 yuan per 10,000. Conventional disinfection: disinfect with bleach or PV iodine every 10-15 days. Water quality improvement/protective agent: once every 15 days, 15-20ppm dolomite per mu, 20-30kg bentonite, 80-120kg zeolite powder, 20-30kg rice flour.

120 kg of shrimp meat is put into each mu, the quantity is 120 kg/mu * 22 shrimps/kg = 2640 shrimps/mu, the male-female ratio is 1:1, 1320 shrimps per mu. The loss during transportation is calculated as 5%, and there are 1254 female shrimps per mu. The price of shrimp is 56 yuan per kilogram, and the cost of shrimp is 120*56 yuan = 6720 yuan. The total number of young shrimps after one year of lobster farming is 1254 shrimps per acre * 2 times per year * 200 times per year = 501600 shrimps per acre per year. The survival rate from spawning to young shrimps is 8%-30%. According to the lowest calculation, the total annual shrimp production is 5016000 * 8% = 40128/mu. After spawning, it can be put on the market for 2-3 months. Each adult shrimp weighs about 50 grams, and the yield per mu is 40128÷10/kg = 4012.8 kg/mu. In this way, the gross profit per mu is 4012.8*10 yuan/kg=40128 yuan/mu.

The profit per mu is about 5,000 yuan, and the current wholesale price per catty on the market is around 20 to 30 yuan, and one mu can produce 1,000 to 1,300 catties of shrimp.

The profit of one acre of shrimp is about 5,000 yuan. Because the profit of shrimp is very high and the fish is particularly expensive, the profit is also very high.

You can earn about 10,000 yuan, but because the investment cost is relatively high, the profit is not particularly high.

The profit from breeding shrimps per acre is about 5,000 yuan, which is a considerable profit.

How to eat river shrimp?

The first method of cooking river shrimp: 1. Cut the pork belly (the kind with lean meat and fat layered together) into 1 cm squares (the thickness doesn't matter, only the length and width); 2. Put oil (more) in the pot, add a spoonful of sugar (white sugar is also fine) (you can put more), and stir-fry until it is sticky (the pot should be smoking at this time, don't be afraid). Pour in the chopped meat and seasoning (thick slices of ginger, cloves (do not crush) of garlic, cinnamon, dried chili peppers, star anise, orange peel (not tangerine peel)), stir-fry over high heat for three minutes, and the meat will turn dark red; 3. Add appropriate amount of salt, one spoon of dark soy sauce, 1/5 spoon of vinegar, half spoon of sugar, two spoons of cooking wine, half spoon of chicken essence, and clear soup (cold water is also OK) until the meat is 3 mm covered, and boil over high heat (it will start to smell fragrant); 4. Pour into a stew pot and simmer over low heat for 1.5 hours. At this time, the soup should be very little and viscous (if there is too much soup, you can simmer over high heat, but you have to stand by and watch), add green peppers (not the kind of lantern peppers that are not very fat), you can add some coriander, then taste the saltiness, and simmer for another 3 minutes. 5. Serve the dish before your saliva drips into the pot, and secretly eat another piece without others knowing. The second way to cook river shrimp: River shrimp can be said to be a common dish, and the cooking methods are definitely different in different places and different people. When buying meat, you must buy pork belly with skin. The fat and lean meat are basically half and half, and the skin must be included, otherwise it is better not to cook it. Wash the meat and cut it into cubes, 2 cm square, without blanching it in water, directly take the pot and pour the appropriate amount of oil (I use peanut oil), put the meat into the pot after the oil is hot, and fry it! Frying is a must, first, the lard in the fat is * out, so it is not greasy to eat, and second, it can increase the aroma of the meat (personal experience... Don't use too strong a fire), fry until the surface of the meat is slightly golden, stop the fire, remove the meat, and pour out the oil. In another pot, pour the appropriate amount of oil, add the onion, ginger, and pepper and stir-fry. Special reminder, add garlic, slightly smash, peel, do not cut, put it in the whole, at least one head, stir-fry together until the aroma comes out, and then it is very important-don't forget to add sugar! Rock sugar is best, white sugar is also OK, at least 1 tablespoon, (I put 2 spoons,) Don't worry about adding too much, the meat is wedding candy. Then pour in soy sauce, not too much. Move quickly, otherwise the sugar will get mushy. After boiling out the juice, pour in the fried meat, stir fry, pour in water (bone soup is best, but I don't have time to boil it), and then - put it in the pressure cooker! (If you have time, or don't have a pressure cooker, then simmer it slowly for at least an hour, the more rotten the better, don't forget to add water during this period). The water in the pressure cooker should be enough to slightly cover the meat, add salt, add spices, boil over high heat, cover and simmer for 25 minutes, turn off the heat and cool naturally, open the lid after there is no pressure, turn on the heat again to collect the juice, add a little MSG when the juice is thick, turn off the heat and serve. The third way to cook river shrimp: Cut the white meat into pieces of appropriate size. Then blanch it in boiling water for 5 minutes and remove the fishy smell and foam! (Secret recipe: adding some white wine is best!) Prepare the seasoning first: pepper, star anise, cinnamon, ginger, onion, cooking wine, soy sauce. Put a little oil in the wok, add white sugar, and stir-fry sugar color. When the color is done, add the prepared seasoning immediately, and then add the meat! (Add the ingredients as soon as there is a slight bubbling!) You can also add some dried chilies to fry together according to your personal preference, which can make the color brighter and the taste richer. After the color is good, you can add water, and then wait for the water to boil~~~ After the water boils, turn the heat down to simmer! When there is not much water left, add salt and turn the heat up to reduce the sauce.

How to make fried river shrimp: 1. Remove the claws, whiskers and legs of the small river shrimp, wash and drain. 2. Heat the wok over high heat and add oil. When the oil is 80% hot (there should be obvious heat above the oil surface and small bubbles in the oil), add the river shrimp and fry for 5-6 seconds, then remove immediately. 3. Keep the heat high and when the oil temperature in the wok rises to 80% hot again, pour the shrimp into the wok and fry for 10 seconds before removing. 4. Leave 1 tablespoon (15ml) of base oil in the wok, heat it over high heat, add scallion slices and shredded ginger and sauté until fragrant, add cooking wine, salt, white sugar and light soy sauce, then pour in the fried river shrimp, shake a few times (or stir with a spatula) and serve.

Recipe for delicious fried river shrimp: 1. Wash the shrimp, remove the shell, and be sure to keep the last section of the shell. 2. Use a bamboo stick to pick out the internal organs. 3. Make about three horizontal cuts on the abdomen, so that the fried shrimp is straight. It looks better. 4. Use a paper towel to dry the moisture. 5. Dip the shrimp in starch. 6. Put the shrimp coated with starch into the stirred egg liquid and dip it evenly. 7. Then put the processed shrimp in dry bread crumbs and coat them with a layer of bread crumbs. 8. After the processing is completed, put it in the refrigerator for half an hour so that the bread crumbs will not fall off easily when frying. 9. Next, fry it in 180-degree oil, and be careful not to burn it, which is not good for your health. Things that are overcooked must be thrown away. The last step is to serve it on a plate. Take a few green leaves that can be eaten raw to pad the plate, add a little potato salad, and put two tomatoes, so that it is as delicious and beautiful as possible.

Which morphological structures of river shrimp are adapted to its aquatic environment: lamellar swimming feet, fan-shaped tail, feather-like gills, slender legs and feet, and eyeballs with particularly high curvature. It is easier to raise mud shrimp. Mud shrimp is commonly known as sand shrimp, which belongs to wide temperature and wide salt shrimp. The temperature range is 10-37℃, the optimum temperature is 17-32℃, and the ability to tolerate low oxygen is stronger than that of shrimp. The general yield per mu can reach 80-150 kg. Pay attention to the following matters in its breeding: 1. Pond conditions and cleaning. It is advisable to choose a freshwater pond or shrimp pond with an area of ​​3-5 mu, a water depth of 1.5-2.5 meters, sufficient freshwater source, no pollution, and sandy bottom. 2. Fertilization and bait cultivation. One week before the shrimp fry is released, filter with a 60-80 mesh silk screen, enter 30 cm of water, and apply 50 kg of basal fertilizer (fermented animal manure) or 5 kg of urea per mu to cultivate basic bait. 3. Shrimp fry are released. Generally, shrimp fry can be released when the water temperature is stable at 18-20℃ in late May. Shrimp fry need to be desalinated for more than a week, and can be released only when the specific gravity is below 1.003. Generally, 30,000 to 40,000 shrimp fry of 0.7-1.0 cm are released per mu, and fry below 0.7 cm need to be temporarily raised. Shrimp ponds can be mixed with 80-150 silver carp fingerlings of 10-20 cm. 4. Feeding. There is basically no need to feed compound feed within one month after the shrimp fry are put into the pond, and they mainly rely on plankton in the pond for food. After one month, feed compound feed, supplemented with fresh fish, shellfish, etc., and the feeding rate is generally 3% to 5% of the shrimp body weight. From July to September, the amount of feed can be appropriately increased, with the principle of no leftover feed. The number of feedings is 2-3 times a day, with 1/3 of the amount during the day and 2/3 in the evening. 5. Adjust water to prevent diseases. 10 days after the shrimp fry are released, water is gradually added, and 10 to 15 cm of water is added every week. In the hot season, the water is changed every 2 to 3 days by 20 to 30 cm. Every half a month or so, 5 to 10 kg of quicklime is used per mu to make a slurry and sprinkled throughout the pond, which not only improves the water quality and bottom quality, but also sterilizes and promotes molting and growth. At the same time, 1‰ to 3‰ garlic bait should be mixed at 15 to 20 days, and it should be thrown for 3 to 5 days. 6. Harvesting. Generally, after 80 to 100 days of cultivation, the shrimp body can be harvested and sold according to market conditions when it is 7 to 10 cm long. It can be harvested by netting or releasing water. It can be transported alive by dry method after 36 hours out of water, and the survival rate can reach 90%. River shrimp farming: River shrimp (also known as green shrimp, scientific name is Japanese swamp shrimp (Macrobranchium nipponense)), which is widely distributed in rivers, lakes, reservoirs and ponds in my country, is a high-quality freshwater shrimp. It has tender meat, delicious taste, rich nutrition, and is a high-protein, low-fat aquatic food that is quite popular among consumers. The market demand for river shrimp is increasing day by day, and it is still popular and expensive. While the prices of many famous fish such as sea bass, sweet-scented fish, eel, turtle, sturgeon, etc. have fallen sharply, the price of river shrimp is still very strong. The highest selling price of river shrimp in Guangzhou Huangsha Aquatic Products Trading Market is 52 yuan to 56 yuan per kilogram. Due to the large market demand and limited wild resources, coupled with the pollution of rivers and waters and the decreasing catch, the development of artificial breeding has a promising prospect. Some experts believe that as long as the breeding is proper, the benefit of raising river shrimp per mu is 6 to 8 times that of raising fish, or even more. It is understood that the breeding of river shrimp is not complicated. Generally, ponds with a water depth of 1 meter to 1.5 meters and sand and mud at the bottom can be used as breeding ponds for river shrimp. The pond should be close to the water source to drain water in time and increase oxygen. River shrimp is omnivorous, has strong reproductive capacity and grows fast, and can be mixed with non-carnivorous fish such as silver carp and dace. If raised well, the economic benefits will be considerable. [Edit this section] Nutritional analysis 1. Shrimp is rich in nutrients, and its meat is soft and easy to digest. It is an excellent food for people who are weak or need to recuperate after illness; 2. Shrimp is rich in magnesium, which plays an important regulatory role in heart activity and can protect the cardiovascular system well. It can reduce the cholesterol content in the blood and prevent arteriosclerosis. It can also dilate the coronary arteries, which is beneficial for preventing hypertension and myocardial infarction; 3. Shrimp has a strong lactation effect and is rich in phosphorus and calcium, which is especially beneficial for children and pregnant women; 4. Scientists at Osaka University in Japan recently discovered that astaxanthin in shrimp helps eliminate "jet lag" caused by jet lag. [Edit this paragraph] Suitable crowd: General population can eat shrimp. 1. It is more suitable for middle-aged and elderly people, pregnant women, patients with cardiovascular disease, people with kidney deficiency and impotence, male infertility, and people with weak waist and legs. It is also suitable for middle-aged and elderly people with calf cramps caused by calcium deficiency. 2. People with chronic diseases and those who are getting angry should not eat shrimp. People with allergic constitutions, such as those suffering from allergic rhinitis, bronchitis, and recurrent allergic dermatitis, should not eat shrimp. In addition, shrimp is a wind-inducing food, so people with skin scabies should not eat it. [Edit this paragraph] Food incompatibility: Shrimp should not be eaten with certain fruits. Shrimp contains relatively rich nutrients such as protein and calcium. If they are eaten with fruits containing tannic acid, such as grapes, pomegranates, hawthorns, persimmons, etc., not only will the nutritional value of protein be reduced, but tannic acid and calcium ions will combine to form insoluble compounds that stimulate the stomach and intestines, causing discomfort to the human body, and symptoms such as vomiting, dizziness, nausea, abdominal pain and diarrhea will appear. Seafood should be eaten at least 2 hours apart from these fruits. [Edit this section] Cooking instructions: Try not to eat shrimps that are red, soft, and falling off if they are not fresh. Do not eat rotten and spoiled shrimps; the shrimp thread on the back of the shrimp should be picked out and not eaten. [Edit this section] Dietary therapeutic effects: Freshwater shrimps are warm in nature, sweet in taste, and slightly warm. They enter the liver and kidney meridians; Shrimp meat has the effects of nourishing the kidney and strengthening yang, promoting lactation and resisting toxins, nourishing blood and consolidating essence, removing blood stasis and detoxification, invigorating qi and nourishing yang, promoting blood circulation and relieving pain, and appetizing and resolving phlegm; It is suitable for patients with kidney deficiency, impotence, spermatorrhea, premature ejaculation, milk blockage, muscle and bone pain, hand and foot cramps, itching all over the body, skin ulcers, physical weakness and neurasthenia. [Edit this section] Dietary therapeutic value: The whole body or meat of various freshwater shrimps such as the long-arm shrimp family. Distributed in freshwater lakes and rivers in the north and south of my country. After obtaining, wash and use fresh or dry for later use. The larger ones can be steamed and peeled for use, also known as dried shrimp. [Performance] Sweet taste, slightly warm in nature. It can nourish the kidney and strengthen the yang, promote lactation, and remove toxins. [Reference] Shrimp contains protein, fat, vitamins A, B1, B2, niacin, calcium, phosphorus, iron and other ingredients. Intravenous injection of shrimp meat extract in dogs can increase the protein concentration in lymph, reduce coagulability, significantly increase the lymph flow in the cerebral duct, and adenosine phosphate (ATP) appears in plasma, but histamine does not increase significantly. [Use] Used for impotence due to kidney deficiency; weak qi and blood, and reduced lactation. [Usage] Boil soup, fry, cook, or grind into powder. [Additional prescription] 1. Shrimp powder: 500g dried shrimp, 1 pair of geckos (or 120g), 60g fennel and pepper each. Add 10g salt and 200ml white wine, stir-fry until crispy, and grind into fine powder. Take 1 spoon each time, twice a day, with warm water. From "Compendium of Materia Medica". The dried shrimp and gecko in the recipe can nourish the kidney and strengthen yang. They are warm but not dry, and are good products for nourishing yang. The warmth of fennel and pepper can help warm the kidney and nourish yang. When used together, the effect is quite remarkable. It is used for insufficient kidney yang, impotence and lack of sperm. 2. Fried shrimp with leek: 150g leek (white bulb is best), 240g fresh river shrimp. Use cooking oil and salt in appropriate amounts and stir-fry them together. This recipe uses river shrimp and leek to nourish the kidney and strengthen yang. It is used for kidney deficiency, impotence, spermatorrhea, enuresis, weak waist and legs, etc. 3. Shrimp wine: 180g fresh river shrimp, stir-fry slightly. Chew it 3 to 5 times a day, and send it down with simmered rice wine. You can take pig's trotter soup at the same time. It comes from "Supplement to Compendium of Materia Medica". This recipe uses fresh shrimp to benefit qi and blood and pass milk, and uses rice wine to help its medicinal effect. It is more effective when taken with pig's trotter soup. It is used for reduced milk. Note: Do not use "shrimp washing powder" to clean shrimps. The Shanghai Food and Drug Administration issued an emergency notice yesterday, prohibiting the use of illegal food additives such as shrimp washing powder. Shrimp washing powder is mainly used by some seafood market stall owners to clean shrimps. The main ingredients are citric acid and sulfites. Although these two ingredients are legal food additives, there are still many unseparated ingredients in shrimp washing powder. Using this product will bring hidden dangers to consumers' health.

How to make fried river shrimp: Wash 3 taels of river shrimp (for shrimp with roe, wash gently and don't wash off the roe). Prepare chopped green onion, ginger, cooking wine, sugar and salt. Heat the oil first and wait for green smoke to come out. Add 3 taels of shrimp in three times (because you don't need to open the oil pan for home cooking). Only a small amount of oil is needed. Fry the first handful of shrimp in the oil pan, the river shrimp will become fat, fry for about 2-3 minutes, and the shrimp will be crispy, then pick it up. Wait for the oil to heat up, then add the second handful, pick it up and fry the third handful. Fry all the river shrimp, leave a small amount of oil and add the green onion and ginger, stir-fry the fragrance, then add a small amount of water, sugar, salt, MSG, and cooking wine, and taste it first to see if it suits your taste. Next, put the fried river shrimp in the pan and turn it a few times to let the juice absorb into the river shrimp. It will be dry when it comes out. Do not add too much water, otherwise the shrimp will become soft. As long as you follow the above method, you will definitely be able to make fried river shrimp that is crispy, loose and fresh.
