The prospect of crocodile turtle culture "/ >

Crocodile turtles look like crocodiles and integrate turtles and crocodiles, so they are called crocodile tortoises, with a meat yield of more than 85%, delicate meat and delicious taste. They are high-protein, high-amino acid, low-cholesterol and low-calorie natural health products. They are also favored by domestic turtle lovers because of their high ornamental value and strong adaptability. Let's take a look at the breeding prospects of crocodile turtles.

The prospect of crocodile turtle culture

Crocodile turtles were introduced into China from abroad not long ago. According to preliminary statistics, the total number of imported turtles so far is about 60,000, of which more than 95% are baby crocodile turtles. Large crocodile turtles are protected internationally, while young crocodile turtles are not protected, so they can be vigorously developed. The current import volume can not meet the needs of our country, and it is still in the development period of crocodile tortoise seedlings at the present stage, which is characterized by the shortage of seedlings and high price.

The unique flavor of crocodile turtles has been recognized by forerunners in economically developed areas. after tasting crocodile turtles, they agree that crocodile turtles do taste delicious, without peculiar smell, earthy smell and strange smell, and taste better than the skirt of soft-shelled turtles. Crocodile turtles are fleshy and have much less fat than ordinary turtles. As long as correct guidance, active encouragement and vigorous development, crocodile turtle culture has a broad prospect.

Culture value of crocodile turtles

1. Economic value: crocodile turtles have been introduced into China and raised in captivity successfully. It is famous for its strong and succulent body, so it is also called meat tortoise, which is the rare and best of turtles. It has the characteristics of high meat yield, rich nutrition, fast growth rate, high economic value and so on. Its meat yield ranks first among turtles, and the meat is delicate, crispy, delicious and has no peculiar smell.

2. Medical value: the nourishing effect is very obvious, which can help yang channel, tonify yin and blood, tonify essence and qi, and have obvious effect on deficiency of essence and blood, fatigue and fatigue, long paralysis and impotence, tuberculosis and cough after a long illness. It is also especially suitable for people with postpartum supplement, anemia, insomnia and mental decline. Tortoise plate has the effect of reducing swelling and is suitable for Yin deficiency and blood deficiency caused by cancer. Glans also have a certain medicinal value.

3. Ornamental value: crocodile turtles have high ornamental value. According to the ordinary seedlings sold on the market, Buddha crocodile turtles are currently the most expensive, followed by real crocodile turtles, mixed Buddha crocodile turtles and North American crocodile turtles. On the other hand, seedlings in Central and South America are more expensive because of less introduction, and the price of mutated seedlings remains high because of their beautiful appearance and less quantity. The price of domestic individuals is very considerable because of their excellent appearance and the careful care of the breeders. It is not that the hormone turtles in the farms can be compared, and more turtles in the farms are sent to restaurants for people to eat. And domestic individuals as pets can not be generalized.

Current situation of crocodile turtle culture

1. The artificial reproduction technology of turtles is not mature: the artificial fecundity (fertilization rate, hatching rate, survival rate) of crocodile turtles is low. Specifically, the low fecundity of crocodile turtles is reflected in the low productivity of mature female turtles, usually only 50% of female turtles lay eggs. In addition, the fertilization rate is low, less than 70%. The hatching rate is unstable, often less than 80%, and the survival rate of young turtles through the winter is low, less than 70%. Crocodile turtles have stringent requirements on environmental conditions, with strong regional characteristics, often because the environmental conditions do not adapt to seriously affect their reproductive capacity. The low reproductive capacity seriously restricted the large-scale production of turtle seedlings and restricted the development of crocodile turtle breeding industrialization.

2. Backward breeding technology and equipment: at present, some units still use soil ponds to raise turtles, some are using soft-shelled turtle greenhouses, have not carried out technical transformation, and have not built an "ecological" greenhouse with multi-function, automatic environmental monitoring, automatic recording and automatic control, which often does not meet the growth requirements of crocodile turtles.

3. The specialization and large-scale production of crocodile turtles are not enough: at present, crocodile turtle farming has not reached the level of specialization and scale, and it has not established a crocodile turtle breeding enterprise group with the integration of scientific research, breeding, processing and sales, nor has it been able to rely on scientific and technological progress, modern management, large-scale mass production and intensive and deep processing of crocodile turtles, let alone reliable market network information.

4. The comprehensive utilization rate of crocodile turtles is low: at present, crocodile turtles are mainly sold to restaurants or hotels, and commodity turtles are sold as a whole scattered and sporadically. For medical research institutes, pharmaceutical factories, aquatic products processing plants and other units, can not collect a large number of fresh, cheap crocodile turtles discards, but directly purchase a large number of commodity crocodile turtles to take their discards, because the cost is too high to bear. Failed to achieve the goal of comprehensive utilization, the value of crocodile tortoise is not fully reflected.
