Know your fish before the counter. 20 sushi species, grade levels, seasons, and food safety notes — all offline.
Pufferfish is an educational reference app for sushi and sashimi enthusiasts who want to learn about the 20 most common fish served in Japanese cuisine — including their grades, seasons, fat content, origins, and important food safety information.
IMPORTANT — EDUCATIONAL DISCLAIMER: This app is for educational purposes only. The information provided is a general reference and must NOT be used as the sole basis for deciding to eat raw fish. Always consult a professional, licensed sushi chef before consuming raw fish or seafood. Raw fish carries genuine food safety risks including parasites and pathogens. Pregnant women, elderly individuals, young children, and immunocompromised persons should avoid all raw fish consumption. Regarding fugu (pufferfish): this species is NEVER to be prepared at home. Tetrodotoxin has no antidote and is lethal. Only eat fugu prepared by a government-licensed fugu chef with the required multi-year training.
