Dr. Kara Dodge and her team from the New England Aquarium conducted an in-depth analysis of 15 years of data collected by disentanglement responders. Their study aimed to unravel the complex web of sea turtle bycatch and mortality, providing insights into the challenges faced by these marine inhabitants.
Bycatch, the unintentional capture of non-target species in fishing gear, has grave consequences for the delicate marine ecosystem. The National Oceanic and Atmospheric Administration defines this phenomenon as a distressing reality, affecting animals such as dolphins, whales, sea turtles, and seabirds that become trapped or hooked while fishermen pursue their intended catch.
Moreover, tracking tagged turtles offered insights into their post-entanglement journey. Many of them survived weeks or even years after being disentangled, showcasing the positive impact of intervention.
“Reducing ropes, which does not mean reducing fishing, will be the best strategy to reduce entanglements,” stressed study co-author Scott Landry from the Center for Coastal Studies, which plays a crucial role in entanglement response efforts and data collection.
Fully disentangling these creatures emerged as a pivotal factor in their survival. Partial disentanglement drastically reduced their chances of making it. Collaboration with fishermen is vital in this endeavor. Timely reporting and waiting for rescue teams to arrive offer the best possible chance for the turtle’s survival.
“We really want boaters to let us know as soon as possible when they become entangled with a turtle so that we can assess the condition of the turtle and provide medical treatment if necessary,” highlighted Dr. Charles Innis, co-author of the study and director of animal health at the New England Aquarium.
The study also explored alternative solutions. For instance, replacing individual fixed gear traps with trawls could potentially reduce the number of vertical lines, thereby mitigating the risk of leatherback entanglements.
This study underscores the power of collaboration, data-driven conservation, and the impact of swift action. By recognizing the critical role we play in preserving the lives of these magnificent sea creatures, we pave the way for a future where leatherback turtles can thrive in their natural habitats.
