They are a popular delicacy in some areas and also make great pets. If you are planning on raising crayfish, it is important that you feed them properly. Crayfish are voracious eaters and consume many foods including vegetables. Crayfish in captivity are often fed a slightly different diet from what they eat in the wild; but as long as their nutritional requirements are met, this will not harm them.

Young crayfish are usually more aggressive feeders, eating aquatic insects and animals. Compared to young crayfish, adult crayfish are more active at night and during cloudy water conditions, and consume more vegetation. Both young and old crayfish will hide beneath rocks during the day if they can, waiting for nightfall before they emerge to feed. They use their antennae to taste and feel food.
