Find a lot, or flip through the zoology, there are too many kinds of ** here.

Overview of Chinese freshwater fish: There are more than 800 species of freshwater fish in China. Among them, the carp genera has the largest number of species, with more than 400 species, accounting for about half of all freshwater fish; There are also many genera and species of catfish and loach, with more than 200 species in the two families, accounting for about a quarter of all freshwater fish; There are more than 200 species in other families such as gobys, snakeheads, and gills, accounting for about a quarter of all freshwater fish.

Among the freshwater fish in our country, some species are widely distributed and can be found almost everywhere.

There are probably five or six varieties of freshwater shrimp.

There are five common ones. 1. **Shrimp, small in size, without aggressive and destructive chelicerae, is a mixed feeding habit.

2. Crayfish, also known as crickets and crayfish in various parts of China, is commonly known as shrimp woman in Singapore.

3. White shrimp, white shrimp is a freshwater shrimp that grows in open waters.

4. Grass shrimp, scientific name Penaeus monodon, also known as black shell shrimp, belongs to the shrimp family.

5. Green shrimp, also known as river shrimp. Green shrimp is widely distributed in rivers, lakes, reservoirs and ponds in China, and is a high-quality freshwater shrimp.

The reason why the shrimp head turns blackShrimp heads contain tyrosinase, under the action of which tyrosine can gradually form quinones, and then form black substances such as melanin and pheomelanin.

In other words, the blackening of shrimp heads is mainly due to the action of enzymes, and has little to do with heavy metals. Even under freezing or refrigeration conditions, tyrosinase remains active, so melanism still occurs. The head of the shrimp is also the internal organs of the shrimp, and if the shrimp happens to eat a lot of dark algae, such as brown algae, before fishing, the shrimp may also have a black color.

The types of freshwater shrimp are:

1. Green shrimp. Green shrimp is one of the genus of giant river prawns that is widely inhabited in China, and is most famous for its production in the Baiyangdian area of Hebei Province and the Taihu Lake area of Jiangsu Province. Green shrimp is a pure freshwater product, living in rivers, lakes and marshes, ponds and ditches, inhabiting the depths of the water in winter, after the water temperature rises in spring, it begins to move to the shore, and in summer it feeds and breeds in the coastal aquatic grass thickets.

2. Grass shrimp. Grass shrimp, scientific name Penaeus monodon, commonly known as ghost shrimp, bamboo shrimp, etc., is an ambiguous shrimp species, is the world's three major cultured shrimp shrimp aquaculture species with the largest aquaculture area and output. It is the largest species in the genus Prawns, with a maximum length of 33 cm and a body weight of 500 600 g, while a mature shrimp is generally long and 137 211 g.

3. Chinese prawns.

In the past, it was often called shrimp because of pairs. Sea-caught non-farmed Chinese prawns are generally 30 grams to 50 grams, and the larger the size, the rarer they are. As a freshwater shrimp species with abundant production, Chinese shrimp is tender and nutritious.

4. Giant river prawn.

Giant river prawn is a large freshwater shrimp, also known as Malaysian prawn, freshwater long-arm prawn, etc. The giant river prawn is large, has a mixed diet, grows fast, is rich in nutrients, and the edible part contains protein and fat, and is delicious.

5. White shrimp. White shrimp is a freshwater shrimp, because the carapace is thinner, the pigment cells are few, the body is usually transparent, and the muscles are white after death, hence the name. China's most famous Taihu white shrimp, also known as the spine-tailed white shrimp, is known as "Taihu Lake white shrimp in the world".

There are five types of freshwater shrimp.

Specifically, it is divided into green shrimp, Roche shrimp, grass shrimp, white shrimp, and shrimp.

Details:

1. Green shrimp. Green shrimp is also called river shrimp, and its scientific name is Japanese giant shrimp.

In China, it is widely distributed and is one of the high-quality varieties of freshwater shrimp.

This shrimp is fresh and tender, nutritious, and especially rich in high-quality protein.

Among the various production areas, Taihu Lake and Baiyangdian Lake are the most well-known.

2. Roche shrimp.

Roche shrimp, large freshwater shrimp, this kind of shrimp grows quickly, has a wide range of eating habits, and the nutrition of shrimp meat is also extremely rich, coupled with the relatively short breeding cycle, it is a very popular species among farmers.

3. Grass shrimp. Grass shrimp, also known as Penaeus monodon, likes to inhabit among aquatic plants, which is also the origin of the name.

The individual growth of grass shrimp is fast, the diet is mixed, the taste is delicious, the nutrition is rich, the market demand is high, and the breeding volume is also large.

The appearance of grass shrimp is an alternating arrangement of dark green, brown and light yellow horizontal spots, which is easy to identify.

Fourth, white shrimp. White shrimp is commonly found in open water, white shrimp is generally not very large, white in appearance, shrimp shell is relatively thin, and looks almost transparent.

Among the white shrimps, the Taihu white shrimp is the most famous, and the white shrimp produced here are extremely tender and have high nutritional value.

Fifth, crayfish. Crayfish, also a type of freshwater shrimp, is a large shrimp with a thick shell that looks like a cylinder.

The living environment is generally a flowing water body with a high oxygen content.

The differences between marine shrimp and freshwater shrimp are: different colors, tastes, shapes, etc.

1. Distinguish from the colorThe color of freshwater shrimp is mostly cyan.

Shrimp are mostly white in color.

2. Distinguish from tasteSea shrimp has its own salt, so when making sea shrimp, the shrimp meat is a little salty, sweet and salty.

The differences between sea shrimp and freshwater shrimp are:

1. Sea shrimp itself has a salty taste, while freshwater shrimp does not.

2. Sea shrimp are basically natural, and most of the freshwater shrimp are artificially farmed.

3. The taste of sea shrimp is relatively fresh and fragrant, and the taste of freshwater shrimp will be slightly firewood.

4. From the point of view, due to the high cost of shrimp farming, the corresponding cost is relatively high.

5. From the point of view of body appearance, the size of the shrimp is generally larger, the color is darker, the shell is slightly thicker and harder than that of the freshwater shrimp, and the branches of the body are also larger, and the shell of the freshwater shrimp is thinner and softer, and the size is smaller.

6. The color of sea shrimp is mostly white, and the color of freshwater shrimp is mostly cyan, which is easy to distinguish from after careful comparison.

7. The main species of marine shrimp is white shrimp, while the main species of freshwater shrimp is giant river shrimp.

8. The whiskers of wild shrimp are very short, the head of the shrimp is short, the teeth are blunt and hard, and the whiskers of freshwater shrimp are very long, and the teeth are sharp and soft.

Freshwater shrimp include green shrimp, grass shrimp, Chinese shrimp, and giant river prawn.

Ghost shrimp, white shrimp and other varieties.
