When Florida families settle down to enjoy a seafood dinner they may not realize the main dish wasn't freshly caught in the nearby Gulf of Mexico, but rather farmed off the coast of Panama.

The process of farming seafood in the ocean, known as mariculture, is a growing trend yet little is known about the trajectories of its development. That's why a team of Florida State University researchers set out to shed some light on the industry.

FSU - Researcher - Rebecca - Gentry - Student

FSU postdoctoral researcher Rebecca Gentry, doctoral student Elizabeth Bess Ruff and Assistant Professor of Geography Sarah Lester examined more than 50 years of data from 1950 to 2016 from more than 100 countries around the world.

Their study, published in Nature Sustainability, outlined several consistent patterns of mariculture taking place globally.

Aquaculture - Component - Food - Production - Gentry

"Aquaculture is an increasingly important component of global food production," Gentry said. "Therefore, understanding patterns of development has important implications for managing our changing global food systems and ensuring economic development, food security and environmental sustainability."

Gentry and her team examined different development trajectories of mariculture production overall and that of specific groups of species, such as fish and crustaceans. They found that countries with relatively stable production farmed a greater diversity of species than countries with other development trajectories.

Example - Countries - Species - Average - Countries

For example, stable countries produced 15.2 species on average, compared to 6.5 for countries who have experienced a crash in production. Lester pointed out that this result suggests that increasing the diversity of...
