In the middle and back of the shrimp head, behind the shrimp stomach, the color is yellow or orange. Shrimp yellow is generally found in mother shrimp, which is the egg of mature mother shrimp. It is delicious and nutritious, but the shrimp yellow of crayfish is very small, which is closely related to other organs such as shrimp stomach and brain. These organs contain more pathogenic bacteria, heavy metals and excrements, so it is impossible to distinguish the shrimp yellow from it, and it is easy to eat these organs together.
