At present, the more common cold-water fish include sturgeon, rainbow trout, pike, brown trout, burbot, Russian sturgeon, flower loach and so on. These species all fall under the category of cold-water fish. When cold-water fish survive in the wild, they mainly eat small miscellaneous insects, microorganisms, aquatic insects and other small things.

1. What are the varieties of cold-water fish in China?

There are some species of golden sturgeon, coho salmon, rainbow trout, mountain sturgeon, sunshine whitespot salmon, tall whitefish, Atlantic salmon, salmon and sturgeon. These are edible.

2. What is the regional distribution of common cold-water fish?

Salmonids, also known as rainbow brown trout, are now common species in some parts of northeastern China. Dogfish, pike is a common species in Xinjiang, China. Cold-water fish, with a fierce temperament, are not much different from the carp in the Yangtze River.

Sturgeon fish, mainly Russian sturgeon, are typical of Siberian cold-water fish. Some species of loach family, such as flower loach, northern loach, etc., are mostly produced in the northeast. The cod, burbot sturgeon, has the most dorsal fin among fish.

3. What do cold-water fish eat?

1. There are many kinds of cold-water fish, but the feeding habits are almost the same, in the wild waters, mainly looking for some small trash fish, small aquatic insects, microorganisms, etc.

2. If it is artificially cultivated, the protein demand of cold-water fish for feed is very high. Among them, animal protein feed accounts for about 60% of the grain. In addition, other nutrients are needed.

3. Maggots are the best bait for special breeding industries. The nutrition is very comprehensive. The dry powder of fly maggots contains up to 60% protein.

Fat is around eight percent. There are also various amino acids and other nutrients. The feed plus dried fly maggots to feed cold-water fish is completely high-quality food.

The growth of cold-water fish is considerable, and the coefficient of bait is low, and generally one kilogram can grow one kilogram after eating one. There are very high benefits.

4. If it is a freshly prepared live fly maggot to feed cold-water fish, then it is equivalent to feed and can be completely replaced. Not only does it grow well and fast, but it also doesn't get sick easily.

At present, the more common cold-water fish are sturgeon and rainbow trout, and the cold-water fish include mountain female trout, coho salmon, Atlantic salmon, and sunshine whitespot salmon.

The varieties of cold-water fish are: koi, yayu, salmon, rainbow trout, fine-scale fish, red-bellied water tiger, Qinghai Lake naked carp, schizophrenia, Thai lion, goby, rock creeper, mosquito-eating fish, wheat ear fish, belly fish, sturgeon and so on.

Species of cold-water fish include sturgeon, koi, goldfish, Chinese betta fish, etc., which are common cold-water fish.

At present, the most common species are sturgeon, rainbow trout, carp, and sturgeon, which are relatively common.

1. Salmon. Salmon, also known as salmon or salmon, is one of the most commonly used fish ingredients in Western cuisine.

2. Rainbow trout. Rainbow trout is a kind of fish of the salmonidae family, Pacific salmon, a cold-water fish of the salmonidae family, and a precious species in pond fishing.

3. Sturgeon. In ancient times, it was called the squid, which belonged to the phylum Chordates. With a body length of 7 meters, it is the largest, long-lived and oldest fish in the world, with a history of more than 200 million years.

4. Yaggi fish. Yayu, belonging to the order Cypriniformes, Cyprinidae, Schizophrenidae subfamily, Schizophrenia genus. Commonly known as:

Elegant fish, heavy mouth, heavy mouth fine scale fish, heavy lip fine scale fish, fine turtle fish. It is an important economic fish in the tributaries of the upper reaches of the Yangtze River, and is also the stocking object of the local development of small and medium-sized water aquaculture.

5. Tuna. Tuna, also known as tuna and tuna, is a large-scale ocean-going important commodity edible fish, most of which are found in the genus Tuna. The warm-water migratory fish of the oceanic orange field is mainly distributed in the low and mid-latitude sea areas, and has a wide distribution in the Pacific Ocean, the Great Circle Front Western Ocean, and the Indian Ocean.

The varieties of cold-water fish are: koi, yayu, salmon, rainbow trout, fine-scale fish, red-ascited water tiger, Qinghai Lake naked carp, schizophrenia, Thai lion, goby, rock creeper, mosquito-eating fish, wheat ear fish, belly fish, sturgeon, salmon trout, salmon salmon, white spot pike, Baikal Yaro, Chinese fish, fish, white cloud goldfish, willow fish, red cross fish, 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 wild cold-water fish in China include the Spoon's cold-water sturgeon, the Dals's cold-water sturgeon and a small number of Sakhalin cold-water sturgeons distributed in the middle reaches of the Heilongjiang River, the lower reaches of the Songhua River and the Ussuri River basin, the Chinese sturgeon, the Da's cold-water sturgeon and the white cold water sturgeon distributed in the Yangtze River and Jinsha River basins, the naked-bellied sturgeon distributed in the waters of Yining, Suiding and Mibuchar in Xinjiang, and the Siberian sturgeon and Pei's sturgeon distributed in the Irtysh River, the Brento Sea and Bosten Lake in Xinjiang.

Healthy aquaculture of cold-water fish is an ecological comprehensive project, and maintaining a good fish ecological environment is an important part of it. Therefore, the healthy breeding of cold-water fish should improve and maintain the environmental conditions around the fish pond and reduce the adverse impact of the surrounding environment on the fishery ecology.

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.

Cold-water ornamental fish include koi, goldfish, white cloud golden silk, Chinese betta, trout, medaka, goby, mosquito-eating fish, wheat ear fish and other species.

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.

Common species of cold-water fish include schizophrenia, schizophrenia, sturgeon, sturgeon, sturgeon, nudibranch, etc.

Introduction to cold-water fish

Cold-water fish is a species of fish, because the water temperature is higher than 20 degrees Celsius, it cannot 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 widest distribution and the most abundant resources, but due to the influence of three major factors: river damming, environmental pollution and overfishing, sturgeon resources have been shrinking, and most of the existing species have been critically endangered.

There is an urgent need for artificial breeding to change this unfavorable situation. Artificial breeding methods mainly include factory circulating water aquaculture, pond aquaculture, cage aquaculture, etc.
