Research Abstract

To reduce incidental death of sea turtles straying into the underwater bag net of the pound net, we developed a new releasing system for allowing turtles to escape spontaneously from the bag net. Loggerhead and green turtles migrating to the coastal area on Japan successfully escaped out through the releasing device in the experiments with using the experimental bag net with the turtle releasing system.
