What do oysters eat to grow and gain weight?

Oysters mainly feed on single-celled plankton and organic debris. There is no special regularity in feeding. Generally, they feed vigorously when the water temperature is 10-25℃, but the feeding intensity is relatively weakened during the breeding season.

Oysters live a fixed life from the time they attach themselves to the object they are attached to. They cannot move on their own and can only open and close their shells. The left shell is fixed, and only the right shell can open and close. They rely on the opening and closing of the right shell to carry out breathing, feeding, reproduction, excretion and other life activities.

When encountering adverse environmental conditions, they close their shells to survive. The long oyster is a wide-temperature shellfish that can live in water temperatures of 0-32℃, and the most suitable water temperature for growth is 15-25℃. It also has a wide range of adaptability to salinity, and is distributed in the salinity range of 10-40‰. It grows faster in sea areas with low salinity.

Raft culture method:

Raft-cultured oyster seedlings need to be temporarily kept in the harbor for more than a month. The oyster seedlings are not easy to fall off before they can be divided and grown in the sea. 4 to 5 days before the division of seedlings, several points should be set in the raft culture area, and a few strings should be taken for trial culture to determine whether the oyster seedlings can adapt and the attachment of harmful organisms in the sea area, especially the attachment of barnacles; if there are too many barnacles attached, they should be temporarily put off from the sea. The culture cycle from seed collection to harvest is about 10 months.

During the oyster cultivation period, the focus is on management, including artificial control of the breeding density, adjusting the water layer through the float, and hanging the oyster seedlings about 3m underwater to adapt to the survival of the seedlings. As the larvae gradually grow and increase in mass, the water layer is adjusted in time through the float; regular reinforcement to prevent typhoon attacks. When a typhoon comes, the infrastructure should be reinforced in advance and cleaned up in time after the typhoon. The load increases on the eve of oyster harvest, and the buoyancy should be increased to prevent the raft from sinking.

Eating oysters generally does not make people fat. Raw oysters belong to the category of seafood. They are rich in protein and trace elements. Oysters are low in calories. Therefore, eating oysters generally does not make people fat, but there are also quantity restrictions. It is recommended to eat no more than 200 grams of oysters per day. In addition, they are mainly steamed or eaten raw, not fried, so eating oysters will not make people fat. Diet should also be strictly controlled, three meals a day, no more than 100 grams of staple food, and exercise for at least 90 minutes a day to avoid obesity. No matter what food it is, it has its own calories. If you eat too much, you will get fat. Take oysters for example, they contain a lot of protein and fat. If you eat too much, you will get fat. So if you want to lose weight, you must pay attention to the amount. It is okay to eat less, but if you eat too much protein and carbohydrates, they will be converted into fat and stored in the body. This is a taboo for people who want to lose weight. No matter how good the food is, you cannot be greedy. In addition, people who want to lose weight cannot rely entirely on diet. In addition to diet, it is recommended that people who want to lose weight should increase their exercise, such as ensuring half an hour to an hour of aerobic exercise every day and combining it with food, so that it can play a role in weight loss.

Oysters feed on microscopic algae, organic debris and single-celled plankton in the ocean. Oysters are filter-feeding organisms, filtering microscopic algae in the water as food. There is no special regularity in oyster feeding. Generally, oysters feed vigorously when the water temperature is 10-25℃, but the feeding intensity is relatively weakened during the breeding season.

Oyster, a Chinese medicinal material. This product is the shell of the Oyster family, such as the Omi oyster, the Long oyster or the Dalian Bay oyster. It can be collected throughout the year. After obtaining it, remove the meat, take out the shell, wash and dry it. The functions and indications are: astringing yin, suppressing yang, stopping sweating, astringing semen, resolving phlegm, and softening hard masses. It is used to treat epilepsy, dizziness, spontaneous sweating, night sweats, spermatorrhea, stranguria, metrorrhagia, leucorrhea, scrofula, and goiter. It is used for palpitations and insomnia, dizziness and tinnitus, scrofula phlegm nodules, masses, spontaneous sweating and night sweats, spermatorrhea, metrorrhagia, stomachache and heartburn. Calcined oyster is astringent and astringent. It is used for spontaneous sweating and night sweats, spermatorrhea, metrorrhagia, stomachache and heartburn. (1) Nourishing yin and suppressing yang: It is used raw to treat hot flashes and night sweats, headaches and dizziness, irritability and insomnia caused by yin deficiency and yang hyperactivity. (2) Softening and dispersing hard masses: It is used raw to treat scrofula and lumps. (3) Solidifying and astringent: Calcined and used to treat excessive sweating, spermatorrhea, leucorrhea, metrorrhagia, diarrhea, etc., often combined with dragon bone. (4) Can also be used for excessive gastric acid, often combined with cuttlefish bone. ① "Ben Jing": It is used to treat cold and heat in typhoid fever, warm malaria, shock and anger, remove stiffness and slowness, rat fistula, and red and white leucorrhea in women. Long-term use strengthens bones and joints. ② "Bie Lu": It removes retained heat in the joints, the coming and going of virtual heat, and fullness; stops sweating, heart pain and qi stagnation, quenches thirst, and removes old blood. It astringes the large and small intestines, stops urination and defecation, treats spermatorrhea, throat paralysis, cough, and heat in the heart and hypochondria. ③ "Yao Xing Lun": It is mainly used to treat metrorrhagia in women. It stops night sweats, removes wind-heat, and relieves pain. It treats warm malaria. It can also be taken with Eucommia ulmoides to stop night sweats. If the patient is weak and has a lot of heat, add Rehmannia glutinosa and Xiaocao.

Oysters feed on microscopic algae and organic debris in the ocean. Oysters are also one of the most resistant aquatic animals. The changeable environment of the intertidal zone over the past 200 million years has trained oysters to have strong resistance to temperature, salinity, air and common pathogens in the sea. When they are exposed to the water at low tide, they can withstand the hot and dry weather in summer, and can also successfully adapt to the freezing weather in winter. They can survive out of water for 1 to 2 weeks, or even 1 month.

Disadvantages of artificial oyster seed

Low survival rate and high cost. Artificially cultivated oyster seedlings are different from naturally grown oysters. Artificial cultivation cannot completely meet the environmental requirements of oyster growth, which leads to a low survival rate. In addition, the unit price of oyster seedlings is about 5 yuan per seedling, and the high cost has become a serious disadvantage of artificial oyster seedlings.
