Solar powered LED lights flashing at a 10% duty cycle (5Hz, 20 min on, 180 mins off) attached to gillnets resulted in a 63% reduction in predicted mean sea turtle bycatch rates. This falls within the range found in previous studies that looked at static lights (40-90% reduction in bycatch), suggesting sea turtle bycatch can be reduced with less power consumption.

The study tested the effect of Lumo Leads on seabird bycatch and catch rates in the Korean tuna longline fleet. Lumo Leads (previously called "safe leads") add weight to longlines by threading the line through a channel, rather than crimping to the line. This can reduce flyback speed and improve crew safety. Lumo Leads also provide protection from exposure to lead weights, and contain optional fluorescent dye to provide an alternative to single-use glow sticks or electric lights.

Dr. Scott Kraus, Vice President and Senior Science Advisor/Chief Scientist, Marine Mammal Conservation, Anderson Cabot Center for Ocean Life at the New England Aquarium, is one of the leading experts on the biology of the North Atlantic right whale, and has extensive experience with his team at the Aquarium in building consensus among industry and scientists in achieving conservation outcomes. These include the relocation of shipping lanes away from sensitive whale habitats, and the development of practical “whale friendly” fishing methods. Dr. Kraus has a PhD.
Dr. Kenneth Baldwin directs the Center for Ocean Engineering at UNH, serves as a member of the University’s Marine Program Executive Committee, and is a Professor of Mechanical Engineering. Dr. Baldwin applies his expertise in engineering and marine environments towards the evaluation of bycatch reduction technologies, including acoustic deterrents and “whale-safe” ropes.

Dr. Andrew Read, Associate Professor and Rachel Carson Chair of Marine Conservation Biology, has conducted field research on marine mammals, sea birds and sea turtles in Canada, Mexico, the United States, South America, and Europe. He holds a number of senior scientific appointments, including President of the Society for Marine Mammology and member of the Scientific Committee of the International Whaling Commission.
Dr. Jeffry I. Fasick is an Assistant Professor of Biology at the University of Tampa in Florida. Dr. Fasick was trained at the University of Maryland Baltimore County, to study the visual pigments of the vertebrate retina, focusing on marine mammals. He did his postdoctoral work at Brandeis University studying the vertebrate short-wavelength sensitive cone visual pigments and the molecular mechanisms associated with wavelength modulation.

Dr. Laurens Howle is an Associate Professor of Mechanical Engineering and Materials Science at the Pratt School of Engineering at Duke University. Dr. Howle's research interests include the disciplines of thermal science, fluid dynamics, and nonlinear dynamics. He has created 3-D rendering of cetacean flippers to study the forces experienced by flippers during movement. He is currently creating a 3-D model of North Atlantic right whales to be used to simulate interactions with fishing gear. Dr. Howle received his Ph.D. from Duke University.
Dr. Stephen Kajiura is an Associate Professor in the Department of Biological Sciences at Florida Atlantic University. His area of expertise is the sensory biology of sharks and rays with an emphasis on the electrosensory system. Dr. Kajiura has conducted research for various agencies, including the National Science Foundation, the Department of Defense, and the National Marine Fisheries Service.
