Many people like to eat shrimp, shrimp is rich in protein and amino acids, can supplement the nutrients required by the human body, and the meat is smooth and delicious, there are many types of shrimp, there are river shrimp and sea shrimp, hair shrimp also belongs to a kind of shrimp, so where is the origin of hair shrimp fry? What are the characteristics of hairy shrimp? Many people don't know it yet, let's take a look at it together.
Where are the raw spots of hairy shrimp fry?
Hair shrimp in the shallow seas along the mainland of China has a wide distribution, of which the Bohai Sea, the Yellow Sea is more, the Philippines, Japan, Taiwan shrimp are distributed, belongs to the tropical subtropical shallow sea important aquatic products, is currently in Hainan, Guangxi, Guangdong, Fujian and other places have been widely farmed.
The original limb of the tail of the hairy shrimp has a large red dot, the abdominal limb is particularly developed, the edge is covered with long pinnate bristles, the whip has long sensory hairs, no external limbs, the compound cornea is large and round, the eye stalk is slender, the tail segment is short, the end is blunt, the frontal horn is short, and the cephalothorax has supra-ocular spines and liver spines.
Every summer and autumn is the reproductive season, preferring to inhabit groups near shallow seas, harbors and low-salt estuaries, with an extremely flattened body, a slightly reddish body, but transparent, and a thin carapace, which is a small phytoplankton shrimp, generally no more than 45 mm in length.
What are the characteristics of hairy shrimp?
In china's coastal waters is widely distributed a kind of hairy shrimp - Chinese hairy shrimp, which is endemic to the Chinese Sea and is a low-salinity species along the coast. Especially in the Bohai Sea area, the production is very large and it is one of the main fishing objects. The dried products of hair shrimp are the shrimp skins that people love to eat.
Hairy shrimp is a type of crustacean cherry shrimp, the form is very similar to ordinary edible shrimp, is a direct fishing object of people, and is also one of the main baits for some economic fish. Some species can also be used as indicator species of water masses and ocean currents. Therefore, hairy shrimp has a very important significance.
The Japanese hairy shrimp, which is slightly smaller than the Chinese hairy shrimp, has a large red dot on the tail limb and is distributed in tropical and subtropical seas.
Hairy shrimp develop rapidly, and Japanese hairy shrimp and Chinese hairy shrimp can breed twice a year. Eggs laid in early summer, after hatching, the larvae grow rapidly, generally two months can grow to adult shrimp, in August this batch of shrimp can be bred. The second generation of this batch of eggs hatches, which can be laid again in the summer of the following year.
Dried products made of hairy shrimp, commonly known as shrimp skin, are delicious, nutritious, and inexpensive, which is quite popular with people. In addition, the shrimp can also be made into shrimp paste and shrimp oil, which can be used to flavor or pickle side dishes with unique flavor. In addition to being edible by humans, the detritus that fall off when drying shrimp skins are called shrimp bran and can be used to fertilize fields. It can be seen that the woolly shrimp is a class of planktonic crustaceans with greater economic value.
In general, the distribution of hairy shrimp is strictly limited to the shallow water areas of the sediment bottom of the riparian estuaries and harbors, and there are often clusters, which are gathered together in large quantities.
Hairy shrimp feed mainly on phytoplankton. The main food of Chinese woolly shrimp is small plankton, of which the main diatoms are round sieve algae. As the individual grows, the zooplankton component of the shrimp's food gradually increases and becomes a meat eater.
The above is the whole content of the production area of hair shrimp seedlings and the characteristics of hair shrimp, hair shrimp in China's coastal waters have aquaculture production, this shrimp is low price and high nutritional value, has been loved by many people.
