River crab is not seafood. River crabs live in freshwater rivers and are river fresh.

River crabs, also called "crabs" and "hairy crabs", have a square shape and a hard texture of the cephalothorax formed by the combination of head and thorax. There is a pair of eyes on the front of the body and two pairs of sharp crab teeth on the sides. The pair of appendages at the very front of the crab are called chelicerae, and the surface is covered with villi; After chelicerae there are 4 pairs of footsteps, flattened and long; The abdominal limb has degenerated.

River crabs often burrow in the mud banks of rivers, rivers and lakes and marshes, are nocturnal, feed on fish, shrimp, animal carcasses and grains, often migrate to the estuary of the sea to spawn in autumn every year, hatch in March and May of the following year, develop into juvenile crabs, and then swim back to the river.

River crabs are not seafood, and river crabs are actually eaten in the same way as sea crabs. River crabs can't stay overnight, and they won't taste good overnight. Sea crabs do not have these particulars, but some people with allergies will have diarrhea when eating crabs, and it is best not to drink beer when eating crabs, which is also easy to spoil their stomachs.

Hairy crabs are not considered seafood. There is still a certain difference between seafood and river fresh.

The growth environment of hairy crabs is generally in freshwater lakes, and the requirements for the growth environment are also very high. In the past, most of them grew under natural conditions, but now hairy crabs basically rely on natural freshwater lakes and artificial enclosure breeding. Hairy crab breeding conditions, light, aquatic plants have special requirements.

Hairy crabs that generally grow in lakes are the highest quality.

The growth of hairy crabs is not so short of a period of time, and the average hairy crab has to experience 2 or 3 years of growth. The original hairy crabs have a special place to grow, and then gradually put the crab seedlings into the major freshwater lakes suitable for the growth of hairy crabs, and there are also some large breeders, purchasing such crab seedlings to breed hairy crabs, of course, as long as the hairy crabs that grow in the lake, they are basically good hairy crabs. This is, of course, different from seafood, which is mainly farmed in the sea, while hairy crabs are mainly farmed in freshwater lakes in the mainland.

There are also many types of crabs, those who live in the sea belong to seafood, those who live in lakes or rivers do not belong to seafood, and the best way to judge if you go to the market to sell them is to see if the crabs are farmed in saltwater, and if they are farmed in saltwater, then they can survive, and those who are not seafood can survive in fresh water.

Crabs belong to the category of seafood. But not all crabs are seafood, and some inhabit freshwater or land.

Of course, this belongs to seafood, but it is not the kind of seafood that is very formal.

They are also creatures of the sea, these are very nutritious, and they can be considered to belong to seafood and the like, so you can eat it with confidence.

River crabs do not belong to seafood, but belong to aquatic products.

Crabs are seafood, but not all frontal crabs are seafood, for example, sea crabs are seafood, and river crabs are not. Seafood, also known as seafood, includes fish, shrimp, shellfish and other categories. Although sea creatures such as kelp are often cooked into food, seafood is mainly made for animals, and in a narrow sense, only fresh seafood can be called seafood, and the classification of seafood is:

Live seafood, frozen seafood.

Coastal areas around the world have their own characteristics for seafood, as evidenced by the sashimi diet in Japan, and the variety of fish dishes in Chinese society. However, there are also many ethnic groups that do not have the habit of eating seafood although they are close to the sea, such as India and the Middle East.

Seafood is not only delicious, but also rich in nutrients. However, in the past decade, the world's seas have been heavily polluted. If you accidentally eat contaminated seafood, you will get food poisoning and even death in severe cases.

Seafood should be purchased from reliable sources. When buying frozen seafood, you should pay attention to the freezing equipment in the shop and whether the storage method is appropriate.

Crabs can be divided into two types: river crabs and sea crabs, crabs cannot be simply defined as river crabs or sea crabs, generally speaking, sea crabs are more common.

There are many types of river crabs in life, such as hairy crabs, clear water crabs, hairy crabs, etc., and there are many types of sea crabs, so I will not repeat them here.

Crab is a more important seafood in life, generally speaking, the harvest season is also the best season to eat crabs.

There are many requirements when eating crabs, and the following points need to be noted:

1. Dead crabs cannot be eaten:

Crabs are high-protein foods, and this type of food has a common problem, which is that after death, a large number of bacteria will be produced in a short period of time.

In particular, it is not recommended to buy and eat crabs that do not know the time of death, as they may cause physical discomfort after eating.

2. These parts of the crab are inedible:

The heart, stomach, intestines, and gills on the crab are inedible because these parts contain a lot of bacteria, especially the crab stomach.

3. How to tell if the crab is plump:

The color of the crab can reflect the plumpness of the crab, and the darker the color of the crab, the fuller the crab meat in the body.
