Fast and Easy
Which Fish? separates seafood into three convenient categories, each with its own icon, so you can pick the best choice quickly.
Search, Browse, and Learn
With Which Fish? you can search for fish and other seafood using both voice and keyboard search. You can also browse seafood and sort the list alphabetically and by sustainability. When you're ready to learn more, you can view the seafood details. Seafood details include availability, population, bycatch, habitat impacts and sourcing.
Not just Sustainability
Which Fish? has more than just information on sustainability. Never had this fish? The "what's it like?" section gives you an idea. Does your fishmonger or supermarket not have this fish? We suggest substitutions. Need a recipe for fish tacos? Check out cooking suggestions. If you're on a diet we also provide nutritional information for each fish in our database.
Your Experience and Privacy are Important
Which Fish? is ad-free.
Your privacy is important. No unnecessary permissions are used, and your data is never collected or sold. The seafood data is stored locally on your device, so the app runs quickly and doesn't need an internet connection to work.
