# Welcome to KosherFish

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.** On every fish page, you'll see 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. You'll find the answer in one box at the top of the page: 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.
