Fins and scales - Fish with both fins and scales are Kosher. Fish with only fins are not Kosher. Of the four types of scales—ctenoid, cycloid, ganoid and placoid—according to law, only ctenoid and cycloid scales are valid; sturgeon scales are ganoid, and shark scales are placoid. The scales must indeed be removable without damaging the fish's skin. As the law says, 'You may eat fish; whatever has fins and scales you may eat...' Bony tubercle, plate-like or spiny scales can only be removed by removing part of the skin; they are not the scales we are talking about here. Some fish with such scales, such as eel, loach, shark, sturgeon and swordfish, are not Kosher fish.

Shellfish, mammals and eggs - All shellfish and mammals (such as whales and dolphins) are not Kosher. Only Kosher fish roe, such as fish eggs or caviar, is permitted, so supervision is necessary.

Fresh fish and fillets - Care must be taken when buying fresh, whole fish, fillets or frozen related products, because it is possible to buy non-Kosher fish, or fish contaminated by non-Kosher fish residue on knives and cutting boards.

Fish sticks may have three problems: the fish, the oil, and the frying utensils and equipment (usually used for non-Kosher fish as well as Kosher fish).

Blood - There is no prohibition on consuming fish blood, except that people may think a person is eating prohibited blood, in which case a sign must be posted indicating that the blood is fish blood. Ritual slaughter is not required.

List of Kosher fish and non-Kosher fish

Important disclaimer! Please read!

This list can only serve as a general guide, because many Kosher fish species share names with other species that are not necessarily Kosher fish. Consumers should be careful when buying fish to ensure that the fish they buy is indeed Kosher fish.

These lists of Kosher fish and non-Kosher fish were compiled by Dr. James Atz, Curator at the American Museum of Natural History in New York, and Dr. Biblis Bibili, Dean of the Department of Ichthyology.

FAQ

What is the key to determining whether a fish is Kosher?
The key is fins and scales: only fish with both fins and scales are Kosher; those with only fins and no scales are not. Of the four types of scales, only ctenoid and cycloid scales are valid by law, and the scales must be removable without damaging the fish skin; sturgeon (ganoid scales), shark (placoid scales), eel, swordfish and the like are not Kosher fish.
What Kosher issues should you watch for when buying fillets or fish sticks?
Be careful when buying fresh whole fish, fillets or frozen products—you may buy non-Kosher fish, or fish contaminated by non-Kosher fish residue on knives and cutting boards. Fish sticks in particular may have a triple problem: the fish itself, the oil, and the frying utensils and equipment (usually used for both non-Kosher and Kosher fish). Fish blood is not prohibited, but a sign should be posted to avoid being misunderstood.
Are caviar, shellfish and marine mammals Kosher?
All shellfish and mammals (such as whales and dolphins) are not Kosher; only roe/caviar from Kosher fish is permitted, so supervision is needed to confirm the source.
