The Huanghe River is a turtle species of China native to China. The Yellow River eel has three distinct features: the carapace is yellow-green, the plastron is yellow, and the carp oil is also yellow. Therefore, the Yellow River Snapper is also called the three-yellow turtle. In addition to these three characteristics, it has the following characteristics: This cricket has a stronger resistance to disease, and now China promotes healthy breeding. The so-called healthy breeding is to minimize the use of drugs in the production process to prevent the use of drugs, to prevent the accumulation of these drugs in the body of commercial lice, the Yellow River lice this species is more suitable for healthy farming methods. In Fuping County, Hebei Province, a large number of wild baboons grow in the spring water stream in the mountains. Because it is a gneiss mountain, and the water quality is slightly alkaline, it is suitable for the growth of earthworms.
Body is flat, oval, dorsum abdomen with a. The entire body is made of soft, leathery skin without horned scutellum. Body color is basically the same, no clear light spots. The head is thick and the front end is slightly triangular. The snout ends are elongated in a tubular shape with a long, fleshy kiss, about the same size as the eye. The eyes are small, located on the rear sides of the nostrils. The neck is long and cylindrical and stretches freely. There were no obvious pods or bullae on both sides of the base of the neck and on the front edge of the dorsal carapace. Carapace dark green or brown, surrounded by hypertrophic connective tissue, commonly known as "skirt." The plastrons are grayish or yellowish-white, flat and smooth, with seven carcasses, on the upper web, the inner web, the lingual web and the lower web, and on the sword plate. Shorter tail. Limbs are flat and the hind legs are more developed than the forelegs. There are 5 toes in each of the fore and hind limbs, and there are moles between the toes. The inner 3 toes have sharp claws. Limbs can be retracted into the shell. The Yellow River Clam lives in the Yellow River Basin, northern China, and the central saline-alkaline zone. It is characterized by cold and warm temperatures, four distinct seasons, and high water salinity and carbonate alkalinity, thus forming its unique features. First, the vitality is tenacious. Even if the water body and the temperature change alternately, the long hibernation and the starvation of the living time show a strong adaptability. The second is that the energy material deposited in the body is rich in various heights. Saturated fatty acids and glial protein content in other species. Among the carcasses of the same specifications, the protein content of the Yellow River carp was 2.8 percentage points higher than that of other carp species, which was 0.6 percentage points higher than that of the wild carp of other species; the third was the orange color of body color, the ellipse of body size. Compact, generous skirts, straight appearance and other aspects of the performance of the goods are better than other species; Fourth, fast growth and strong resistance. Shanghai aquatic tycoon Cai Yuanqi / Zhu Jin, etc. <<Chinese sturgeon seven groups of juveniles--aquaculture stage performance evaluation>> (Journal of Fisheries) China's Chinese sturgeon on behalf of the seven local varieties, in greenhouse temperature (30 degrees) conditions A randomized complete block design method was used to conduct a comparative test of the aquaculture performance of more than 300 days from larvae to larvae. The result was that the difference in average daily increments among the seven cultivars was extremely significant (F>0.01). The order of daily average weight gains was: Yellow River Crest> Huai River Crest> Poyang Lake Cock> Dongting Lake Cock> Taiwan Crest> Taihu Lake > Chongming é³–, the Yellow River é³– extremely significantly better than other varieties (T> 0.01).
