Jesse Senko, a National Science Foundation Postdoctoral Research and Conservation Scientist at Arizona State University, led a novel multi-hazard study. They recently deployed a solar-powered illuminated fishing net into the Cortez Sea that has reduced sea turtle bycatch by 63%. This novel approach is making strides in the protection of vulnerable marine species. It seeks to make coastal fisheries more sustainable, a key priority for small island communities around the globe.
To address this, Senko used controlled experiments to deploy solar-powered nets across Mexico’s Gulf of California. The findings were remarkable, indicating a 97% reduction in sea turtle entanglements. The LED lights in the nets flicker on and off in order to conserve power. This ingenious design allows them to stay on for more than five consecutive days without sun. Collectively, this advanced technology represents an incredible accomplishment. Employing solar energy and the power of a bright, flashing light, it safely deters sea turtles from entering fishing gear.
Collaboration with Fishermen
Senko’s program is based on industry collaboration with fishers to create safer fishing practices. He works closely with fishermen in coastal North Carolina and has gained insights from Mexican fishermen, specifically brothers Juan Pablo Cuevas Amador and Felipe Cuevas Amador. Their concept for how to use solar-powered, LED navigation lights to ship shape fishing buoys led to the creation of this artful project.
“For us, it’s important that it be done in collaboration because, with what they know and what we know, we can do quite interesting things.” – Juan Pablo Cuevas Amador
This collaborative, hands-on approach has brought the LUMO to life and opens the door for some exciting technological advancements. It has created a deep sense of ownership among local fishermen. The brothers said that they were pleased with the research team’s openness to taking their suggestions and guidance throughout the project.
“They took us into account and gave us the freedom to give our opinions and make modifications.” – Juan Pablo Cuevas Amador
Together, Senko and the fishermen are using science to create new fishing gear that reduces bycatch of sea turtles, sharks, and other endangered species. Their mission is to protect a more prosperous future for our ocean, climate, and coastal communities.
The Importance of Sea Turtles
In addition to their beauty and majesty, sea turtles are crucial agriculture for healthy oceans’ ecosystems. Senko emphasizes their ecological significance by stating, “Sea turtles are important for maintaining healthy oceans, which are needed to sustain resilient fisheries.” These magnificent monsters of the ocean have ruled the seas for more than a century million years. They perform important ecological roles that other species cannot substitute for.
While the 63% reduction in sea turtle bycatch seen in this study is a produce a very positive baseline, there is still work to be done. Senko is not satisfied to leave it at that. He wants to raise this reduction to 95%. He thinks there’s room for improvement through better refinement of the technology and techniques used.
“A 63% reduction in sea turtle bycatch is a magnificent starting point. However, there’s no reason why that can’t be improved, right?” – Jesse Senko
The creative deployment of solar-powered illuminated nets represents a breakthrough opportunity to transform commercial fishing practices and better protect marine wildlife.
Future Plans for Commercial Availability
Jesse Senko is on a mission to save the ocean, with hands-on experience conducting research. His goal is to have solar-powered, illuminated nets commercially available in the next two to three years. To foster adoption, he’s working with Fishtek Marine, a UK-based manufacturer, to produce these nets and help fishers get access to them.
Senko’s vision takes the active step of protecting endangered species. Simultaneously, it improves the economic status of millions who rely on inshore coastal fisheries. Small-scale coastal fisheries feed almost half of the entire planet. They protect food security and promote economic resilience in our coastal communities.
“It’s a win-win in the sense that you’re getting a light that lasts significantly longer, and it also seems to reduce bycatch just as effectively as lights that require replaceable batteries.” – Jesse Senko
With this initiative, Senko hopes to encourage more sustainable fishing practices. This smart, forward-looking initiative will help keep marine ecosystems healthy and local economies thriving.
