Basa (known by the scientific name of Pangasius bocourti), is a member of the catfish family. (It should NOT be confused with bass fishes, which are typically kosher). Basa, like other members of the catfish family, do not have scales, which is a requirement for a fish to be considered kosher.

 

According to Chabad, who received their information from the Orthodox Union, basa is NOT a kosher fish.
