August Birth Fish Calendar
High summer pairs river and reef: of August's 18 species, look for Ayu sweetfish, Pike conger, Abalone, and Rock oyster. The Largehead hairtail — a silver fish whose peak months include August — is the birth fish for August 15.
Our birth fish are an independently compiled system: our editors prefer species whose peak season (shun) includes each date, and the list embraces seafood of every kind — crustaceans, shellfish, and cephalopods included. Other sites may assign different fish, but this page follows our own mapping throughout.

What lands in August
August belongs to summer's rivers and reefs. The Ayu sweetfish, a freshwater fish traditionally caught through the summer, shares the calendar with Pike conger, said to be at its best in the heat. Rock oyster and Abalone — shellfish of the summer season — round out the reef.
Offshore, the blue fleet passes through: Yellowfin tuna and Mahi-mahi list August among their peak months, while the Largehead hairtail, at its best from August into autumn, glitters silver on the market. The Long-arm octopus, a cephalopod whose peak runs from summer into early autumn, keeps the calendar's octopus corner busy.
How to enjoy August birth fish
- Choose by fish words: blade and flash, the words given to the Largehead hairtail, make a striking card.
- Taste the season: ayu is a shioyaki classic, and pike conger suits a light nimono.
- Pair it with the birthday color: summer-festival colors beside the day's fish make a lively gift.
- For gifts and cards: an ayu birthday suits anyone who loves mountain streams.

- Because there is no official standard, every site sets its own assignments. Ours follow one published rule — peak season (shun) includes the date — applied the same way all year.
Our birth fish are an original editorial system, not an official standard: each date falls within its fish's peak season (shun). The list includes seafood — crustaceans, shellfish, and cephalopods — as well as freshwater fish. See our editorial policy for how it is compiled.Editorial policy
