Sheatfish (Siluriformes) is not Kosher.

The sheatfish, which belongs to the order Siluriformes, is not considered kosher according to Jewish dietary laws. In determining whether a fish is kosher, it must meet specific criteria set forth in the Torah. Here are the key points for fish to be kosher:

• Fins and Scales: A fish must have both fins and scales to be considered kosher. The scales must be visible to the naked eye and easily removable by hand or with a utensil without damaging the skin.

Siluriformes, which include catfish and sheatfish, typically lack the type of scales that meet the kosher criteria. Therefore, they are generally classified as non-kosher.

Summary

• Sheatfish (Siluriformes): not kosher due to the absence of the proper type of scales.
