The implementation of measures to effectively conserve and manage sharks, relies heavily on scientific knowledge for efficient advocacy. Unfortunately, basic information regarding the natural history and biology of many shark species in Costa Rica is lacking.
PRETOMA has been studying the relative abundance of sharks and turtles in Costa Rican longline and artisinal fisheries since 1999. Since 2004, through partnerships with the Shark Research Institute and the Southwest Fisheries Science Center, PRETOMA is studying migrations of pelagic sharks in Cocos Island National Park and the EEZ of Costa Rica, using state of the art acoustic and satellite telemetry. In 2006 PRETOMA started a whale shark sightings network, involving dive companies, fishermen, tour operators, pilots, and the general public.
