The difference between Pipi shrimp and crayfish
The scientific name of Pippi shrimp is squid, which is a kind of sea shrimp and is produced in the coastal areas of China. Every spring is the season of laying eggs, and it is best to eat at this time. The brain of fat shrimp is full of oil, and its meat is very tender, delicious and nutritious. These kinds of shrimp in the market: rock shrimp, prawn, prawn and river shrimp are the most common, but they are usually not easy to distinguish. Their differences:
1, compared with Loki shrimp head, the most striking feature is that the breastplate of the shrimp head is covered with gonads, which looks a bit like crab roe, and the pliers are mostly blue. Online fresh ones cost 7 or 80.
2. There are many kinds of prawns. At present, there are three kinds of prawns in the market: China prawn, Penaeus vannamei, Japanese prawn and Penaeus monodon. The meat of prawns is a little more delicate, and the male prawns don't have big pliers. The forehead sword of Penaeus vannamei in China is very long, which is even longer than the mouth, while the forehead sword of Penaeus vannamei is relatively short. On the other hand, from the point of shrimp whiskers, the shrimp whiskers of China shrimp are longer than those of Penaeus vannamei. The shape of Penaeus japonicus is easy to identify, the shell is hard and the color is dark. Because of its bamboo-like grain, it is also called "bamboo shrimp". Penaeus monodon is related to Penaeus japonicus. Its shell is dark and its body is covered with dark brown and khaki stripes.
3. Neopenaeus monodon, also known as Neopenaeus monodon, has extra stripes on its body and some yellow spots at the end of its feet, and its posture is particularly special. The forehead of the new prawn with a knife forehead is straight, and usually there are 7 to 9 serrations on the upper edge, which is different from ordinary prawns. Penaeus vannamei 1 kg 150, Penaeus vannamei 1 kg 3, 40. Almost all the cheap prawns on the market are fakes of Penaeus vannamei, which look similar in posture but taste different.
4, river shrimp (green shrimp), with flaky swimming feet, fan-shaped tail, particularly high curvature of the eyeball, slender legs and feet, river shrimp.
Which is better, shrimp or crayfish?
These two kinds of shrimp can't be compared. Let's look at personal tastes and tastes. Pippi shrimp, also called squid shrimp, is the strongest shrimp in the water. They can easily destroy the shell of shellfish by quickly extending the attacking hammer joint, and the feet on the body can ensure rapid movement. Its "punch" speed is so fast that even the most agile fish and shrimp in the water can't escape.
It is understood that a broken shrimp with a body length of about 25 cm is as powerful as a 0.22 caliber pistol bullet, and there is a record of breaking a strengthened glass aquarium in the laboratory. Even a very small individual can easily smash an ordinary aquarium. Usually, Pippi shrimp will not be put in an aquarium, because it will kill all the creatures in it.
