No matter what kind of shrimp, there will be a black linear object on the back, which is the so-called shrimp line. Shrimp thread is actually the intestine of shrimp, and there will be some residual excrement in it, so even if you don't want to remove it, eating it will only affect the taste and will not cause harm to your health.

If it's fresh shrimp caught on a fishing boat, it's ok not to go to the shrimp line, or it's not necessary to go to the shrimp line for very small shrimp, because there is very little excrement left in it, but it's best to remove the shrimp line for shrimp cultured in shallow water to avoid affecting the taste.

If it is boiled, insert a toothpick into the second section of the shrimp back and pick out the shrimp line directly. If you make shrimp with garlic vermicelli, stir-fried prawns, braised prawns, etc., you can directly open the back and take out the shrimp line, which will also make you taste better.

The first situation: sea shrimp

If it's fresh shrimp just caught from the sea, the old fisherman said that there is no need to go to the shrimp line, just clean it and cook it in the pot.

Because deep-sea shrimp, its living environment is often relatively clean, so there will not be too much dirt, impurities and other residues in the body and shrimp line.

The second situation: cultured shrimp.

In fact, the shrimps we usually eat are all freshwater cultured shrimps, and the living environment of this kind of shrimp is far less good than that of sea shrimps.

Therefore, there are often a lot of dirty things in the shrimp line, and it will taste very fishy. The old fisherman said that if he bought freshwater shrimp, he would have to remove the shrimp line with toothpicks and other things in advance.
