Detection of scalloped hammerhead sharks in Apra Harbor and adjacent waters, Guam using Environmental DNA (Old ID 23578)
Role
Principal Investigator
Description
Scalloped hammerhead sharks (Sphyrna lewini) are anecdotally reported in Apra Harbor, Guam, but their spatial and temporal patterns of occurrence are not well understood. Lack of knowledge of population abundance, distribution, and habitat use also extends across the geographic range of the Indo-West Pacific subpopulation. All S. lewini are nationally protected under the Endangered Species Act, and their occurrence within Apra Harbor is of concern to management and conservation strategies and mission-essential operations of the U.S. Department of Navy. This project will determine the temporal and spatial distribution and habitat use of the scalloped hammerhead shark within Apra Harbor and Orote Peninsula nearshore waters.
