Exposure to high temperatures even for brief periods, such as during marine heatwaves, can produce chages which can be inherited by the next generation of fish, according to new study on seabass.
Researchers say high early-life temperatures provided a "growth advantage" to smolt after transfer, but still have some "invisible" effects on fish health.
FAO GLOBEFISH figures show that both countries increased revenues from two major Mediterranean aquaculture species in 2025, despite declining or only modest growth in export volumes.
