Abstract

Research on the turtle's response to green Light Emitting Diode (LED) light emitting diode to reduce turtle bycatch was carried out on a laboratory scale. The aim of the study is to analyze the behavior response of turtles to green LED lights on a laboratory scale. The research used experimental laboratory by observing turtle behavior towards green light in controlled conditions. Testing was done by observing the response in the form of movements and speed of the juvenile turtle to the green LED lights. The turtle species that became the object of this observation were 11 green turtles (Chelonia mydas) with Curve Carapace Length (CCL) 45-50 cm carapace length. The results showed that sea turtles had visual sensitivity conditions and levels, and showed the same response to each treatment. The use of green LED lights provides an avoidance response to turtles. Based on the avoidance response, green LED lights can be used as an alternative in reducing turtle bycatch in gillnet fishing activities.
