Abalone culture should pay attention to matters
2. Submerged caisson cultivation: The breeding equipment is a large-scale cage of 2m2m0.8m steel skeleton, which is sunk in the seabed for breeding, and some are open on the upper side and both ends, with a number of staggered transverse partitions in the middle, and the opening part has a belt. The cement tanks of the zippered nets are sunk on the sea floor for cultivation, and the feed is mainly seaweed such as kelp. The breeding environment of the abalone is stable compared to the eel culture, and the growth effect is also good, but the feeding and management are relatively difficult.
3. Perimeter pool type cultivation on the seashore: In the intertidal zone where the selection conditions are suitable, the dike is built in a pond, stones, cement boards, and tiles are placed in the pool as hidden attachments to the abalone and left on the upper part of the pool wall on the sea side. There are several water outlets, which serve as exchange channels between the pool and the outer seawater during the ebb tide. After the ebb tide, the seawater in the pool should be maintained at a depth of about 1m, and the bait is mainly seaweed.
4. Land-based aquaculture (1) Multi-layer tank aquaculture: It adopts a multi-layer long strip-shaped shallow water tank and is used together with screens, attachment plates and other equipment. The sink is 0.5-0.7m wide and 0.3-0.4m deep. The length is generally between 1-10m. The layer spacing is about 0.5m. Some of the bait are mainly seaweed, some are mainly bait-based, and the breeding density is 3-5cm. 200-400 square meters, more than 6cm abalone 100-150 per square meter.
(2) The plastic tank aquaculture pond in the pool is 20-40m2 in depth, 1-1.2m deep in the cement pool, and the plastic box is 39cm in length, 30cm in width and 12cm in height. Each box is stacked for 5-7 boxes. A stack and bundled, the bundles are placed in the pool and arranged in rows, with operating channels in each row. The daily water supply is not less than 3-6 times that of the cultivation water body, 24 hours continuous ventilation, and the food is fresh kelp or Dried kelp.
Vitamins:
Vitamin A: Retinol. Carotene compounds responsible for transmitting light sensation in the retina of the eye. Deficiency leads to night blindness.
Beta carotene: An antioxidant which protects cells against oxidation damage that can lead to cancer. Beta carotene is converted, as needed, to vitamin A. Food sources of beta carotene include vegetables such as carrots, sweet potatoes, spinach and other leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive carotene in the diet can temporarily yellow the skin, a condition called carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1: Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a disease of the heart and nervous system.
Vitamin B2: Riboflavin, essential for the reactions of coenzymes. Deficiency causes inflammation of the lining of the mouth and skin.
Vitamin B3: Niacin, an essential part of coenzymes of body metabolism. Deficiency causes inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6: Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic acid): Folic acid is an important factor in nucleic acid synthesis (the genetic material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An essential factor in nucleic acid synthesis (the genetic material of all cells). Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C: Ascorbic acid, important in the synthesis of collagen, the framework protein for tissues of the body. Deficiency leads to scurvy, characterized by fragile capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A steroid vitamin which promotes absorption and metabolism of calcium and phosphorus. Under normal conditions of sunlight exposure, no dietary supplementation is necessary because sunlight promotes adequate vitamin D synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone deformity (rickets) in children.
Vitamin E: Deficiency can lead to anemia.
Vitamin K: An essential factor in the formation of blood clotting factors. Deficiency can lead to abnormal bleeding.
Nutritions:
For the treatment of nutritional disease, any of the nutrient-related diseases and conditions that cause illness in humans. They may include deficiencies or excesses in the diet, obesity and eating disorders, and chronic diseases such as cardiovascular disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also include developmental abnormalities that can be prevented by diet, hereditary metabolic disorders that respond to dietary treatment, the interaction of foods and nutrients with drugs, food allergies and intolerances, and potential hazards in the food supply. All of these categories are described in this article. For a discussion of essential nutrients, dietary recommendations, and human nutritional needs and concerns throughout the life cycle, see nutrition, human.
