The Caribbean Is Ripe For Offshore Aquaculture – Researchers Find A Wealth Of Potential In The Region·
There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet’s growing population will only further increase the need for animal protein, one of the most resource-intensive types of food to produce.
With this in mind, a team led by researchers at UC Santa Barbara’s Bren School of Environmental Science & Management and the Marine Science Institute (MSI) looked at the feasibility of fish farming, or aquaculture, in the Caribbean. The team focused specifically on offshore mariculture—ocean-based operations done far from shore—which offers a promising alternative to land-based and coastal aquaculture, where space is limited and environmental impacts are often high.
The group discovered that even under conservative estimates, the region could produce over 34 million metric tons of seafood per year. This potential yield is more than two orders of magnitude larger than the region’s current seafood production. The results appear in the journal Nature Sustainability.
“The Caribbean has a large potential for off-shore mariculture,” said Lennon Thomas, the study’s lead author, who serves as a project researcher at MSI.
