Episode 201: No Fish Left Uncounted

How do you count two fish, three fish or even a school of fish? In Dry Tortugas National Park, located 70 miles from Key West, Florida, a group of scientists have joined forces to conduct a massive fish census. In this unprecedented collaboration, experts from four different agencies unite to count and analyze fish data from select sites. Changing Seas follows highly-skilled science divers as they determine the size of fish populations in hopes of better understanding how fishing pressures and environmental changes affect populations of marine resources within the park.

Home to the world’s third largest barrier reef, Florida’s vast coral tract plays a significant role in the development and protection of many marine organisms. These delicate stony structures help support commercially-viable species that form the foundation of the state’s large fishing industry. For one to two weeks, scientists at sea maintain a rigorous diving schedule as they count and record everything from staghorn coral to red groupers. What will the divers find? Are fish populations recovering in South Florida?
