Unpublished report to the Indian Ocean Tuna Commission (IOTC) and Indian Ocean and South East Asia (IOSEA) Marine Turtle Memorandum of Understanding

Interactions between sea turtles and fishing activities have been listed as a significant threat to sea turtles. This study aimed to assess which sea turtle species/populations in the Indian Ocean (IO) are at risk from interactions with tuna-related fisheries. The approach used was a desktop study to compile (1) all available data on sea turtle population demographics, rookery sizes and at-sea distributions; and (2) collate all information of longline, purse seine and gillnet effort and sea turtle interactions in the Indian Ocean.
