What fish are Jews allowed?

Answer 1

This was rather difficult to figure out what you meant, but if you mean what kinds of fish they can eat, the answer is all of them. Jewish people cannot eat shellfish.

Answer:

A lot of work has been done around scaleless and scaled fish to meet Kosher food guidelines. A fish must have both visible scales and fins to be Kosher. Shellfish, shrimp, scampi, prawns, lobsers, octopus and squid are not fish and are not allowed. Non-Kosher fish include:

• Basa (Pangasius bocourti)
• Billfishes
• Blowfish
• Burbot
• Catfishes
• Cutlassfishes
• Dogfish
• Eels
• Freshwater gars
• Freshwater Cod
• Goosefishes
• Hoki
• Lampreys
• Jacks
• Lomosuckers
• Lumpfish
• Snailfishes
• Marlin
• Monk fish
• Ocean pout
• Oilfish
• Puffers, blowfishes, swellfishes, sea squab (Sphoeroides species)

In Jewish dietary laws (kashrut), only fish with both fins and scales are considered kosher. Examples include salmon, tuna, and haddock. Shellfish, such as shrimp, crabs, and lobsters, are not permitted.
