Kosher Fish Requirements

Question: What are the requirements for fish to be considered kosher? Answer: To be kosher, a fish must have both fins and easily removable scales, as commanded in the Torah. Sharks and dolphins, which only have fins, are not kosher. A unique aspect of kosher law is that all fish with scales also have fins, supporting the Torah's divine origin. Unlike meat, fish do not need ritual slaughter and can be eaten immediately if they have the required signs. When buying from non-Jewish stores, you must verify these signs yourself, either by seeing the whole fish or at least the skin with scales. Processed fish products from non-kosher sources are not permissible, even if from a kosher species.
