It is a large freshwater fish, and the adult fish can even reach more than one meter in length, and mainly lives in the Heilongjiang River basin in China.

Zheluo is more precious, the reason is that the fishermen catch a lot of fish, so that the number of Zheluo breeding and ** can not reach a balance, now the number of Zheluo is decreasing, people can catch less and less Zheluo, if not controlled, one day will completely disappear from people's sight.

4. Yarrow fish.

The yarrow is also a freshwater fish, its body size is small, and the adult yarrow fish is generally around two or two. In some areas of Jilin Province, the yarrow fish is called"Ya Green", Kaijiang.

The above is the introduction of the varieties of Northeast cold-water fish, in fact, there are also very small bodies in Northeast cold-water fish, such as willow roots.

Wait. Compared with ordinary freshwater fish, the amount of fat contained in the body is relatively small, and the protein content is also higher.

The varieties of cold-water fish include salmon, rainbow trout, fine-scale fish, Qinghai Lake naked carp, schizophrenia, sturgeon, yayu, spotted cucumber, naked cucumber fish, black spotted loach, black-backed loach, jerro salmon, black and white pike, silver rump fish, Baikal yarrowfish, white pike, yarrow, etc. Cold-water fish is a species of fish, mainly according to the requirements of fish for the living environment, especially the water temperature, higher than 20 degrees of water temperature can not survive, so it is called cold-water fish.

Cold-water fish have a history of more than 100 million years and are called "living fossils in water". China is one of the countries with the largest number of cold-water fish species, the most widespread distribution and the most abundant resources.

The species of cold-water fish culture are divided into two categories: salmon trout and sturgeon, and their primitive living environment is mountain streams and rivers, and the natural water quality is good and the water temperature is low. Therefore, when choosing a water source for cold-water fish farming, spring water and river water with fresh water quality should be selected, and the water temperature should be 10 to 18. Scatter.

The cold-water fish breeding pond is better to have a rectangular, round-blunt structure at all corners, there is no dead angle to go to the water reasonably, the fish can be evenly distributed in the whole pool, the fish pond is 4 meters wide, and the length is not more than 15 meters.

Among the cold-water fish, there are koi, goldfish, white cloud golden silk, Chinese betta fish, etc., and wild fish include sturgeon, salmon trout, and fine-scale fish. Koi fish and goldfish are the best cold-water ornamental fish to keep alive, while salmon trout and sturgeon are the two major species in cold-water fish farming.

Species of cold-water wild fish include schizophrenia, sturgeon, salmon trout, salmon, pike, Baikal yarrow, sturgeon, sturgeon, willow and many others.

Domestic cold-water fish to koi, goldfish is the best to raise, koi and goldfish are mild, the diet is more mixed, the water temperature and water quality requirements are not strict, the adaptability is relatively strong, can live in the water temperature environment of 5-30 degrees.

Salmon trout and sturgeon are the two major categories of cold-water fish farming, their original living environment is mountain streams and rivers, requiring good water quality and low water temperature, so it is best to choose spring water or river water with good water quality when breeding, and the water temperature is 10-18 degrees.
