Hanshou turtle, special product of Hanshou County, Hunan Province, China National Geographical Indications. Hanshou County is located on the bank of Dongting Lake in the north of Hunan. Since ancient times, it has been known as the “land of fish and rice”. The artificial breeding of turtles has been the first in the country and won the reputation of the “hometown of turtles”. Hanshou turtle is an authentic Chinese sturgeon, which has been identified as an excellent variety by Hunan Province. Compared with other turtle breeds, Hanshou turtle has large body flakes, wide and thick skirt, and egg fat in the abdomen; strong body and flexible crawling. It has strong immunity, fast growth rate and high survival rate. When eaten, its meat quality is pure, tender and delicious, chewy, and its nutritional value and medicinal value are superior to other populations.

Hanshou County is located in the Dongting Lake in the north of Hunan Province. It is the hometown of turtles in China. It has created a precedent for the artificial breeding and purification of Chinese turtles. It has created the first turtle research institute in China. Hanshou has carried out artificial release of turtles over the years. The amount of wild turtles has rebounded rapidly. Hanshou County has always been rich in turtles. The county is Taibai Lake, Xinao Lake, Nanhu Lake, and Dike Lake. In 1974, the county began to breed turtles. In 1981, after the technical appraisal of Hanshou turtle culture, more and more Hanshou people invested in turtle culture. In the 1990s, we will fully promote the construction of agricultural industrialization based on turtles. In 1996, Hanshou County's turtle production value reached 308 million yuan, accounting for one-third of the county's total agricultural output value, becoming the second largest agricultural project after grain production. More than 8,000 farmers engaged in turtle farming, There are 120 departments and units engaged in turtle breeding, more than 30,000 people involved in turtle breeding, the intensive area of ​​turtles has reached 12,000 mu, the area of ​​fish breeding is 40,000 mu, and the relatives are 335,000 kilograms. It has 8.15 million, has a greenhouse, a greenhouse area of ​​70,000 square meters, and has 2 million juveniles, with an annual output of 500,000 kilograms of soft-shelled turtles. In 1998, Hanshou turtle culture was included in the national standardization demonstration project. In 2010, the county has a turtle breeding area of ​​50,000 mu, an annual output of 1,800 tons (600 million), an output value of 3.2 billion, the output value accounts for 30% of the county's aquaculture, and the output accounts for one-third of the country. Ecological, large-scale, standardized breeding road. Hanshou has become China's largest breeding base for turtles and seedlings and an important commodity breeding base. Chinese sturgeon, cubs, relatives, commodities and processed products have been sold to more than 12,800 units in 29 provinces, municipalities and districts in China, and have been resold to Europe, America, Korea, Japan and Southeast Asia through coastal open cities. All over the place. In 1986, Hanshou turtle was recognized as an excellent variety by Hunan Province. In 1995, Hanshou County was awarded the title of “the hometown of turtles”. In October 2010, the State Administration for Industry and Commerce officially approved the registration of the trademark of Hanshou turtles with geographical indications; in November, the Hanshou turtle was approved by the General Administration of Quality Supervision, Inspection and Quarantine to implement the protection of geographical indication products; in March 2012, it was identified by the provincial bureau as the province. The standardized breeding of soft-shelled turtles. Quality characteristics The soft-shelled turtle is a creature that is almost contemporaneous with dinosaurs. The turtle has lived in the Dongting Lake area very early. Since ancient times, Hanshou County has the habit of fishing, hoarding and holding turtles. The artificial breeding of turtles is the first in the country. The parent of Hanshou turtle is selected from the area where sputum and swill are confluent. The descendants of these parents are also cultured through long-term pond culture, which forms a good quality gene of Hanshou turtle, which has a large body and a wide skirt. Appearance characteristics such as "thickness" have also been formed in the long-term accumulation. Compared with other soft-shelled turtles, Hanshou turtle has five different sensory characteristics: (1) large body flakes, wide and thick skirts; (2) red and white in the abdomen, visible fine blood vessels, no plum spots, triangular spots and Black spot; (3) the back end edge of the back has a protruding longitudinal pattern and small condyle; (4) the abdomen in the juvenile stage is orange-red; (5) the fat in the abdomen is egg-yellow. Hanshou turtle is a Chinese sturgeon with good quality and rich nutrition. Compared with other local turtles, Hanshou turtle has the characteristics of wide and thick skirt, fast growth rate and high survival rate. Its meat quality is pure, tender and delicious, its nutritional value and Medicinal value is also superior to other populations. Hanshou turtles contain a high proportion of umami amino acids, especially the proportion of the five umami amino acids (ASP, GLU, GLY, ALA, ARG) relative to the total amino acid amount reached 42.89% and 59.23%, respectively. Hanshou turtle has a high protein content and contains 18 kinds of amino acids and multivitamins, especially trace elements such as calcium, phosphorus, iron, zinc and potassium. In addition, the content of selenium in the muscle of Hanshou turtle is 258 μg/kg, that is, 25.8 μg/100 g, which is 1.2 to 9.4 times that of ordinary animal meat. The culture environment Hanshou County is located in Xiangbei, Dongting Xibin, with a paddy field area of ​​41.98 thousand hectares. Within the county, Taibai Lake, Xinao Lake, Nanhu Lake, Weidi Lake, Qingni Lake, Da Nan Lake, Qingshui Lake and other waters. The territory belongs to the monsoon humid climate zone that transitions from the mid-subtropical to the northern subtropical zone. The annual average pressure is 1012.1P, the annual average temperature is 16.7 °C, the monthly average temperature is above 9 °C for 9 months, the accumulated temperature of ≥20 °C is 86400h °C, and the annual frost-free period is 274d. The rainfall is abundant and the annual average relative humidity is 82%. The annual average solar radiation is 106.87kl/cm2. Hanshou's unique climate and geographical features provide a good ecological environment for the growth and culture of Hanshou turtles. The breeding water source of the 24 towns and towns that mainly produce Hanshou turtles is mainly from the West Dongting Lake. It is made up of the combination of swill and swill, with unique composition, stable water quality and rich nutrition. Diatoms and cryptophyta in water are the dominant plankton, and they are the main bait for the main foods of natural turtles. The selenium content of snails, scorpions, crickets, shrimps and the like is particularly rich. According to the “Baichuan Liuwang”, the selenium content of freshwater prawn is as high as 29.65μg/100g. Selenium-rich natural bait will inevitably produce high selenium Hanshou turtle.
