KosherFish answers one question fast: is this fish kosher? Type a fish name in the search box, and you get a clear kosher or not-kosher answer with the reason behind it.
The site covers hundreds of fish species, each checked against the same rule the Torah lays out in Leviticus 11:9. A fish is kosher only if it has both true fins and scales. Everything on the site flows from that one test.
What you can do here #
- Look up any fish. Search by common name, scientific name, or a market nickname.
- See why. Every fish page shows whether it has fins and scales, plus a plain-language note on the kosher status.
- Find it in another language. Each page lists the fish name in Hebrew, Yiddish, Spanish, and more, so you can match what is on a foreign label or menu.
- Check warnings. Some kosher fish get swapped for non-kosher look-alikes at the counter. The site flags those.
- Take it with you. The free iOS and Android apps work offline at the fish market.
A quick word before you start #
KosherFish is a guide, not a halachic ruling. It is built to help you make a smart first call and to point you in the right direction. When a purchase really matters or a fish is unusual, ask a trusted rabbi.
The fastest path: three steps #
Here is the fastest path from a fish name to a kosher answer.
Step 1: Search the name #
Type the fish name into the search box on the homepage. You can use the common name (salmon), a nickname or market name (lox), or even the scientific name if you have it. Suggestions appear as you type.
Step 2: Open the fish #
Click the fish from the results. The top of the page gives you the answer in one box: a green “Kosher” badge or a red “Not Kosher” badge, with a short reason.
Step 3: Confirm the details #
Right under the status, the fins and scales checklist shows you the why. A kosher fish is a green check on both rows. Scroll a little further for the description, foreign-language names, and any warnings about look-alike fish.
If you get a typo #
The search is forgiving. Spell salmon as “salmn” and it still surfaces the right fish. If nothing comes up at all, try a shorter piece of the name or a different name the fish goes by.
