What do freshwater crabs eat? I caught one from the river today. I don't know how to raise it. Let's talk about it

The diet of freshwater crabs is mixed. Eating mud is a superficial phenomenon, that is, eating algae and other nutrients in mud and filtering them out.

Mainly based on animal feed, the main varieties are fresh fish, snail meat and so on. And then gradually increase the amount of plant concentrate, such as wheat, corn, soybean meal, etc.
