- Evaluate movements, behavior, and habitat utilization of silky sharks in the equatorial and tropical EPO from in-depth analyses of existing data obtained from archival tags
- Understanding population structure and movements is essential for stock assessments, particularly for sharks
- The information available about movements, behavior, and habitat utilization of silky sharks in the EPO is limited
- Understanding behavior and habitat utilization is important for effective conservation measures and for ecological risk assessment analyses
- Relevance for management
- Improve management advice on silky sharks based on spatially-structured stock assessments; habitat utilization information is useful for mitigation and spatial management
- 24 months (2020-2021)
- Workplan and status
- The archival tag data for silky sharks collected for previous IATTC projects funded through the EU will be analyzed in depth and compared for describing geographic variation in movements, behavior and habitat utilization in a manuscript to be submitted to a scientific journal.
A manuscript describing Silky Shark movements released in two discrete areas of the EPO is in preparation and will be submitted during the 2nd quarter of 2022.
