The shrimp is omnivorous and partial to animal feeding. In the adult stage, copepods and polychaetes are the main prey, and synthetic feed, other organic debris and benthos are also eaten. The culture period is100 ~120 days, and the shrimp body can reach 8 ~10 cm.
Penaeus monodon can be cultured in both sea and fresh water, with strong adaptability, especially in fresh water, which has fast growth, wide feeding habits, few diseases and high success rate.
(A) pond conditions
(1) pond selection
Require sufficient water, good water quality, solid land and convenient drainage. The area of shrimp pond should be 0.134 ~ 0.67 hectares, the water depth should be1.2 ~1.5 meters, and the rectangle is better. The shrimp pond should have an independent water inlet and drainage channel for irrigation and drainage. The inlet and outlet water should be filtered by screen silk to prevent harmful organisms from invading the shrimp pond. It is best to dig annular ditches or diagonal ditches at the bottom of the pool, with the depth and width of 0.5 ~1m and 3 ~ 5 m respectively, so as to protect against cold and summer.
(2) Clear the pond
For the newly-built shrimp pond, water can enter as long as it is exposed for 2 ~ 3 days, while for the old pond, it needs to be dredged and exposed for one winter, and weeds at the pond side should be cleaned strictly. The method is as follows: 20 days before the shrimp fry are stocked, use quicklime 100 kg every 0.067 hectare, first melt the lime in a small pool and sprinkle it all over the pool while it is hot. Or 0.067 hectares of10 ~15 kg bleaching powder is spilled in the whole pond, and 20 ~ 30 cm of water is needed to clean the bottom of the pond with bleaching powder.
(3) culturing basic bait
After cleaning the pond for 7 ~10 days, 50 cm of fresh water was injected into the pond, and the water inlet was filtered with 80 mesh sieve silk, and then fertilizer was applied on sunny days to cultivate basic biological bait. Fertilization can be spread evenly with fermented and matured organic fertilizer (chicken, pig, cattle, sheep manure, etc.)100 ~150 kg per 0.067 hectare, or put the organic fertilizer into woven bags and push it to the bottom of the pond; If inorganic fertilizer is used, 2 kg of urea and calcium superphosphate 1 kg should be used in the whole pond every 0.067 hectare. To use inorganic fertilizer, the same amount of topdressing should be done every other day. Generally, the color of water in 7 ~10 is light yellow-green, and the transparency is 30 ~ 40 cm, indicating that the biological bait in the water is rich. Then, the water temperature and pH value are determined. If these conditions are suitable, shrimp seedlings can be put in.
(2) fry stocking
(1) seed dilution
At present, the larvae of Neopenaeus vannamei used for breeding are mostly produced in factories. Generally, the proportion of seawater used for breeding is1.015 ~1.020, so it must be domesticated and gradually desalinated before being moved to fresh water for breeding. The degree of desalination must meet the pond standard, that is, it can only be directly moved into fresh water for cultivation after the proportion of water is1.003, and the whole desalination process must be gradually desalinated for more than two days.
(2) Seeding amount
Macrobrachium nipponense, larvae with a body length of 0.7 ~1.0 cm, is reared singly, with 20,000 ~ 50,000 larvae per 0.067 hectare; Mixed culture with freshwater fish (only mixed culture with grass carp, bighead carp and silver carp), it is best to raise temporary shrimp seedlings with a body length of more than 2.5 cm, and the number of seedlings released should be reduced according to the specific situation.
(3) temporary support
Dig a small temporary culture pond in the corner of the shrimp pond, accounting for about 3% ~ 5% of the area of the shrimp pond. First, intensively cultivate the shrimps needed in the shrimp pond for15 ~ 20 days, and when the length of the shrimps generally reaches1.0 ~1.5 cm, the overflow water will naturally disperse to the whole pond.
(3) Feeding management
(1) water quality management
The water quality requires a pH value of 7.0 ~ 8.0, dissolved oxygen of not less than 4 mg/L, a yellow-green color with a transparency of 30 ~ 40 cm, water 10 cm every five days in the early stocking period and the highest water level in the high temperature season in summer. Patrol the pond frequently and change the water frequently to improve the water quality. Conditional ponds are best equipped with aerators to ensure fresh water quality during the whole breeding period.
(2) Feeding management
Before 1 month, shrimp larvae were mainly fed by plankton in the pond or supplemented by a small amount of fine granular feed, and after 1 month, artificial compound feed was mainly used, supplemented by fresh water ...... > >
Question 2: What does metapenaeus ensis eat? metapenaeus ensis feeds metapenaeus ensis to eat plankton in the water. The shrimp is omnivorous and animal-eating. In the adult stage, copepods and polychaetes are the main prey, and synthetic feed, other organic debris and benthos are also eaten. The culture period is100 ~120 days, and the shrimp body can reach 8 ~10 cm.
Metapenaeus ensis doesn't need to feed the microorganisms in the water specially. Just change the precipitated tap water once every one or two days. Remember to put the water shallowly and make sure there is enough oxygen. If you want it to grow better, put a little glucose. Remember, too much will kill it.
Metapenaeus ensis also eats broken snails and small miscellaneous fish. Plankton is used as bait or supplemented by a small amount of fine particle feed. In addition, you can also mix it with feed, fish and shrimp, feed and worms, so that the nutrition will be more balanced. Cooked sweet potatoes mixed with rice bran plus shrimp feed and so on.
Neo-prawn with knife forehead is commonly known as mud prawn, hemp prawn, tiger prawn, tiger prawn, sand prawn, red claw prawn and Lu prawn, and it is called metapenaeus ensis commercially.
It belongs to Arthropoda, Crustacea, Decapoda, Swimming suborder and Penaeidae. The maximum length can reach 19cm. Shrimp in coastal shallow water has the advantages of strong omnivorousness, wide temperature, wide salt, rapid growth, strong disease resistance and so on, and it can withstand hypoxia and has the habit of diving to the bottom. Because of its thin shell and fat body, the meat is tender and delicious and can be sold alive, it is favored by consumers. It is an excellent variety of "shrimp cultured lightly" at present.
Question 3: What does metapenaeus ensis eat? In the early stage of metapenaeus ensis culture (shrimp larvae are 3 cm long), that is, the first 1 month of shrimp larvae entering the pond, it mainly relies on plankton in the pond as bait or supplemented by a small amount of fine granular feed.
After the shrimps are released into the pond 1 month, they are fed with artificial compound feed (mainly macrobrachium macrobrachium feed). The daily feeding amount is 4%~6% of the shrimp weight. In the peak growth season, some crushed snails and small miscellaneous fish are added where conditions permit. The feeding amount should be flexibly controlled according to the season, water temperature, climate and water quality, and adjusted in time. If the water temperature is between 25℃ and 30℃, the basal-tailed shrimp will eat heavily, so we should seize the opportunity to feed more and add 0.3%~0.5% additives such as vitamins and bone meal to the feed to ensure the nutritional needs of shrimp growth. Feeding during the day accounts for 1/3 of the daily feeding amount, accounting for 2/3 in the evening, and can be added at midnight in the growing season.
Question 4: What fruit can you eat after eating metapenaeus ensis? It is best not to eat any fruit before or after eating shrimp. Most fruits contain vitamin C, which will produce arsenic trioxide to some extent, that is, arsenic ...
Question 5: What shrimp can't be eaten after eating metapenaeus ensis? Avoid eating with some fruits. Shrimp is rich in nutrients such as protein and calcium. If they are eaten with fruits containing tannic acid, such as grapes, pomegranates, hawthorn and persimmons, not only will the nutritional value of protein be reduced, but tannic acid and calcium ions will combine to form an insoluble combination, which will cause discomfort, vomiting, dizziness, nausea, abdominal pain and diarrhea. Seafood should be eaten with these fruits at least 2 hours apart.
Shrimp and food containing vitamin C are mixed (not suitable for frying)
Shrimp and pumpkin: Eating together can cause dysentery, and you can detoxify with black beans and licorice.
Shrimp juice: The same food will cause diarrhea.
Shrimp should avoid vitamin C (pills).
Eating less makes the stomach ache unbearable, and eating more leads to death.
Shrimp and tomato eating together are prone to food poisoning.
Shrimp skin soybean: the same food will cause indigestion.
Shrimp skin and red dates: the same food will be poisoned.
Shrimp vitamin C: Eating together can cause arsenic poisoning.
Shrimp avoids golden melons, but eating them will lead to diarrhea. Rescue: eat black beans or licorice water. Shrimp in Haihe River should never be eaten with pork and chicken, which will lead to liver and kidney failure.
Question 6: It doesn't matter what you are afraid of eating metapenaeus ensis, you can eat it.
Dietary taboos of patients with hepatitis B and rest of patients with nursed back to health depend on the degree of hepatitis activity. When hepatitis is obviously active (serum transaminase is obviously increased), you should rest completely or even stay in bed. If hepatitis is basically static (serum transaminase is completely normal), you can exercise properly. Of course, all hepatitis patients should avoid heavy physical labor and ensure adequate sleep.
Patients with hepatitis should pay special attention to eating a high-protein and low-fat diet. You should eat more high-protein foods such as bean products, eggs, milk and fish, and eat more vegetables, especially green leafy vegetables. At the same time, you should keep your weight to prevent fatty liver from being overweight. Hepatitis patients should pay special attention not to eat too much sugar, because the three major metabolism of human body mainly depend on the liver. If you take a lot of sugar after suffering from liver disease, it will inevitably increase the burden on the liver and induce diabetes. After you get hepatitis, you should ban alcohol, don't drink alcoholic beverages, and avoid taking drugs that damage the liver. For some common diseases, such as colds and coughs, it is appropriate to take Chinese herbal medicines or Chinese patent medicines.
Patients with hepatitis should pay attention to maintaining optimism. Traditional Chinese medicine believes that the seven emotions of "happiness, anger, worry, thinking, sadness, fear and surprise" are different emotional reactions of the human body to external objective things, and as long as they are adjusted normally, they will not lead to diseases. If there are strong or long-term seven emotions * * *, it will disturb the normal physiological activities of human body, make the function of viscera and qi and blood disorder, and lead to the occurrence or aggravation of diseases. Because "the liver governs anger", patients with liver disease are more irritable, while patients with chronic hepatitis B are mentally stressed and emotionally unstable due to long-term illness. Therefore, it is necessary to pay special attention to maintaining a good attitude and not worrying too much about the harm of the disease itself, otherwise moping all day will affect sleep and appetite, and even aggravate the condition. In a word, a good mood is very important for the recovery of hepatitis patients.
Question 7: What does metapenaeus ensis eat and what living environment does it need! What food do you need! Ask an expert to point out the amount of new shrimp, also known as metapenaeus ensis, sand shrimp. There is no strict choice of sediment, and it widely inhabits the coastal shallow sea area with sand and mud bottom. The suitable water temperature is10 ~ 37℃, and the optimum growth temperature is17 ~ 32℃. When the weather is cold and the transparency is high, it is hidden in the bottom material, and the depth can reach 8 ~10 cm. In the appropriate temperature period, the daytime often lurks in the bottom material, only two eyes and tentacles are exposed. They hunt at dusk and have more activities at night. It can adapt to a wide range of salinity, grow in fresh water and survive in seawater with salinity above 35‰. Strong tolerance to low dissolved oxygen. It can live normally in water with pH value of 7.0 ~ 9.0.
The shrimp is omnivorous and partial to animal feeding. In the adult stage, copepods and polychaetes are the main prey, and synthetic feed, other organic debris and benthos are also eaten. The culture period is100 ~120 days, and the shrimp body can reach 8 ~10 cm.
