Crayfish is also called crawfish, and while some people don’t bother removing the line, many do. If you choose to remove the intestinal vein, this is how to do it.

How to Devein Crayfish

    1. With one hand, hold on to the tail while gently twisting it to remove from the body.
    2. Crack the shell gently by pinching toward the center. You just want to crack the shell, not crush it in small pieces. Remove the shell. Identify the vein, and remove.
    3. Alternately, the meat and vein may be removed by twisting it from the shell. Grab the end of the tail and gently twist, removing the tail and vein at the same time.
