Greek hatcheries produced 213 million gilthead seabream juveniles and 159 million European seabass juveniles in 2025, according to the Hellenic Aquaculture Producers Organisation (HAPO), known in Greece as ELOPY.
Seabream output rose by almost 3% year on year, while seabass production increased by 13%.
| Species | Juveniles produced in 2025 | Year-on-year change | Supplied to Greek farms |
|---|---|---|---|
| Seabream | 213 million | +3% | 92% |
| European seabass | 159 million | +13% | 93% |
Greece has 24 hatcheries, with a reported combined maximum capacity of 556 million juveniles a year.
Total production reached 384.1 million in 2025, with a value of €81.8 million. Seabream and seabass accounted for 372 million; the remaining 12.1 million were other Mediterranean species, mainly porgy and meagre.
HAPO forecasts that combined seabream and seabass juvenile production will rise by around 1% in 2026, to 375 million.
The figures indicate that most Greek seabream and seabass juveniles were supplied to domestic farms. However, the report does not quantify imports or the farms’ total juvenile requirements, so it does not confirm that Greece is fully self-sufficient.
