New study earmarks three species for offshore farming potential

Atlantic salmon, sea bream and cobia farming is adaptable to most climate change scenarios, say scientists.

A new analysis suggests that open-ocean aquaculture for three species of finfish is a viable option for industry expansion under most climate-change scenarios, reports Phys.org.

To assess the possible range for aquaculture, researchers looked at three species of fish – Atlantic salmon, which grows fastest in sub-polar and temperate waters; gilthead seabream, found in temperate and sub-tropical waters; and cobia, which is in sub-tropical and tropical waters.

"We found that all three species would shift farther away from the tropics, which most models say will heat more than other regions," said Dane Klinger, a former postdoctoral researcher at Princeton University and lead author of the study.

"Production of Atlantic salmon, for example, could expand well into the higher latitudes, and though the trailing edge of their range may face difficulties, adaptation techniques can offset those difficulties.
