Description

A kind of culture method of eel

technical field

The invention mainly relates to a cultivation method, in particular to a cultivation method of eels.

Background technique

Eel, whose scientific name is eel, is a traditional rare fish and one of the most mysterious fish in the world. Its growth process is extremely peculiar. It first lays eggs and grows in sea water, and then enters fresh water to grow. Eels can still survive after a year and a half of "hunger strike", and the life span of farmed eels can be as long as 50 years. The nutritional value of eel is very high, so it is called soft gold in water, and it has been regarded as a nourishing and beauty product in China and many parts of the world since ancient times. Japanese people often eat delicious grilled eel rice in winter to drive away the severe cold and keep energetic. Eel is rich in nutrients. Every hectogram (100g) of fresh eel contains 61.1g of water, 16.4g of protein , 21.3g of lipid, 0.1g of sugar, 1.1g of ash, 95mg of minerals (mg), 230mg of vitamins , and calcium , phosphorus, iron, sodium, potassium and other substances. Books such as "Wonderful Medicine in the Hand" , "Shenghui Fang" , "Compendium of Materia Medica", and "Honcho Shikan" in Japan have recorded the miraculous therapeutic effects of eel: tonic, warming intestines, expelling wind, detoxification, beauty, healing Wind, treat damp beriberi, damp wind arthralgia between the waist and kidney, treat malignant sores, treat fatigue caused by cadaveric qi, warm the waist and knees, raise yang, and treat infantile malnutrition and women's leukorrhea. The meat of eel is rich in protein, vitamins A, D, E, minerals and unsaturated fatty acids DHA/EPA. It can provide the nutrients needed for human growth and maintenance of life. Eating eels for a long time is extremely helpful for strengthening the body, increasing vitality and nourishing the skin, especially for pregnant women and infants. Compared with other animal foods, eel has higher content of vitamin A, vitamin E and polyunsaturated fatty acids contained in fat . It is worth mentioning that river eel is rich in antioxidant nutrients, such as vitamin A, which contains nearly 2,500 international units (IU) per 100 grams of eel, which is 50% of the recommended daily intake of vitamin A for adults in Da. The substance calcium contains about 100 mg per 100 g of eel. Scientific research shows that eel is one of the fishes with the highest content of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Supplement necessary nutrients. DHA can promote the brain development of children and adolescents, enhance memory, and also help the elderly prevent brain function decline and Alzheimer's disease. Medical experts have also found that eel contains beneficial ingredients of fish oil and vegetable oil, and is an ideal food for supplementing essential fatty acids and amino acids. The content of zinc, polyunsaturated fatty acid and vitamin E in eel is very high, which can prevent aging and arteriosclerosis , so it has skin care and beauty effects, and is a natural and efficient beauty food for ladies.

Contents of the invention
