There are many wild shrimps in coastal areas, and there is nothing in the shrimp line that needs to be removed. There are few Penaeus vannamei farmed in the local market. Look at this shrimp. If the shrimp line is too dark, it tastes better. If it's not too dark, it's unnecessary. For prawns, shrimp is unnecessary, and locals in Guangdong eat crayfish less. Then the shrimp in the pond. You are right. Although the pond looks like a river, because of the stagnant flow of the pond, we will also remove the shrimp line for the shrimp that is too big, but most of the shrimps don't go to the shrimp line.
Sashimi is certainly not uniform, but a matter of personal preference. Some people describe Cantonese people like this. People who fly in the sky don't eat except airplanes, and people who swim in the water don't eat except boats. Some dishes go to the shrimp bank to look good, and a catty of boiled river shrimp goes to the shrimp bank for help.
A catty of shrimp can pick out a lot! I'm not pretending now. Life is like this. If you want to eat, you must eat clean. I would rather spend more time taking it out than eating it whole! Shrimp line is a more exquisite "high-end" way to eat. You can also buy a catty of sea shrimp, half of which will go online and half will not go out. What is the difference? As for river shrimps, especially river shrimps, there are hundreds of them in a catty. Do you want to try this line? Anyway, I don't pay attention to shrimp line. I eat fried shrimps with leeks.
