The answer is edible.

The reasons are as follows:

First, pond catfish, a kind of edible fish, belongs to Siluriformes and Siluridae in classification. Belonging to tropical and subtropical fish, widely distributed in southern China, it is not only a nutritious consumer product, but also a tonic with medicinal value. Therefore, it has great market potential and is an effective breeding object for farmers (fishermen) to get rich.

Secondly, people often say that it is unsanitary, which refers to the living environment and life preference of the pond lice. This kind of fish usually lives in a dirty environment and sewage.

Third, the pond lice have a wide range of recipes, and they like to eat other fish, worms, blood, rotten food, feces and so on.

Fourth, the wild ones are less polluted by human activities, so they should be cleaned and cooked thoroughly before eating, so as to effectively kill bacteria and parasites.
