This month, the Florida Sea Grant program in Miami-Dade County participated in Biscayne National Park’s (BNP) inaugural “Trap Line Throwdown”. Together, we removed years’ worth of accumulated trap line from BNP’s beautiful mangroves.
Trap line is rope that connects a surface buoy to the trap below, indicating the location of traps to fishers. If traps become separated from their line, the line washes ashore and can become completely entangled due to wave action, winding mangrove roots, and passing storms.
Five boats went out and collected a whopping total of 3,051 pounds of trapline, equivalent to 18.67 miles! We couldn’t just leave the other debris behind, so our volunteers helped grab another 1338.5 pounds, bringing the grand total to 4389.5 pounds!
We extend our thanks to for helping supply cutting tools! They made a huge difference in being able to remove this debris.
If this project sounds like something you might be interested in, be sure to make your way to BNP next year for some beach clean-ups, where you can take a more active part in keeping our community clean. We’re proud of the work we get to do with BNP and can’t wait to cut out some more trapline next year!
