About Fins Attached (from their website): Historically, research on sharks has been slow and inconsistent. The remoteness and inherent dangers and difficulties of studying sharks in their natural habitat and a lack of funding are to blame. However, we are beginning to understand sharks and their behavior, where sharks go and why they go there. Satellite tags and acoustic telemetry allow for scientists to study migration patterns and shark behavior. This leads to further conservation zones being designated for highly migratory species.

It is important to not only understand shark migratory patterns, but to also identify nursery areas where sharks go to give birth. Marine protected areas (MPAs) must be established to protect these nursery areas so that the young sharks have a chance of surviving to adulthood.

Both satellite and acoustic tags can be equipped to record depth, temperature and location information. This kind of science requires a tremendous amount of money, and this money is usually not available unless the end results could lead to useful applications and profits. Research into sharks for their own sake is more difficult to fund. However, this is essential for their survival. The scientific data is needed to back-up any conservation argument.

Status of shark populations at Cocos Island and other eastern tropical Pacific islands is unknown, although evidence indicates heavy exploitation by fisheries. The Cocos project includes a telemetric study of several species of sharks to determine their movement patterns, connectivity and residency and a shark censusing program to examine population size and dynamics in Cocos Island and other islands in the Eastern Tropical Pacific (ETP). This information is necessary to understand the behavior, ecology, and population state and dynamics of sharks, which will constitute baseline information to implement a management strategy for the conservation of sharks in the region.
