The economic value of black dolphin farming

Black dolphin is a food with high protein, low fat and low cholesterol. Melanin can scavenge free radicals and prevent lipid peroxidation in human body, thus delaying aging. The iron content is 3 times that of soft-shelled turtle, and it is also rich in anti-cancer and anti-cancer elements zinc and selenium, while the content of cholesterol and saturated fatty acids is very low, so it is an ideal nutrition and nourishing health food. in line with the consumption trend of natural health black food in the 21st century. Because the black dolphin meat is almost all muscle, the fiber is more delicate than rabbit meat, and does not contain fishy taste, so it has the characteristics of easy cooking, crisp and fast cooking. Black dolphin meat taste sweet flat, beneficial qi and blood, detoxification effect, used to treat weakness, old kidney deficiency, postpartum anemia and other diseases. The testes of black dolphins can be used as drugs for the treatment of epilepsy, and serotonin can be extracted from dolphin blood.

The fur of the black dolphin is a good raw material for processing fur clothing and handicrafts, and its processability and decorative performance can be comparable to that of mink skin. it can be used to make fur clothing, shawls, gloves and dolphin series toys. Black dolphin can also be used as an ornamental animal to provide favorite pets for pet breeders, especially children.

Black dolphin is a small animal, docile, easy to Baoding, its blood use value is high, collection is more convenient, can be widely used in physiology, medicine, immunity, reproduction and bioengineering experiments. According to reports, Japan, South Korea, China and other countries have selected black dolphins as experimental animals, the annual demand is more than hundreds of thousands, and the domestic will be far more than hundreds of thousands in the future. Therefore, the black dolphin is an ideal and widely used experimental animal.

Black dolphin feces and urine is a high-quality organic fertilizer. An adult black dolphin accumulates 90 kilograms of fertilizer per year. The contents of nitrogen, phosphorus and potassium in black dolphin feces are much higher than those in other livestock and poultry feces. It is estimated that 100 kg of black dolphin dung is equivalent to 10.92 kg of ammonium sulfate and 1.97 kg of potassium sulfate, and black dolphin fertilizer can improve soil structure, increase organic matter and improve soil fertility. The experiment in the yellow mud (acid) soil of Fenghuang Mountain in Chengdu City, Sichuan Province showed that the organic matter of the yellow mud soil treated with black dolphin dung increased by 42.3%, and the nitrogen content increased by 43.86%, which significantly improved the soil quality and soil structure.

To sum up, according to China's national conditions and the advantages of the black dolphin industry, the development of grain-saving black dolphins has a very good breeding prospect, of course, the most important thing is to correctly guide, seed speculation is not a real skill, the development of commodity economy is the future.
