Abstract
In order to improve knowledge of the spatial ecology of the Arabian Sea humpback whale (Megaptera novaeangliae), five implantable satellite tags were deployed on whales encountered off the southern coast of Oman during February 2014. All tags were deployed on males and in an area associated with the seasonal presence of singing males. Three of five tags implanted provided location data for a mean of 46 days (range: 41-55d); two tags failed to provide locations given poor attachment. A preliminary review of location and track data show localized behaviour and transits between Halaniyat Bay and the Gulf of Masirah. Habitat utilization kernel density estimates confirmed previously identified hotspots. These areas are experiencing rapid industrialization and increased human use. Although analysis is based on a small number of individuals with modest tracking durations, tags provided important insights to understanding the spatial ecology, habitat-use and direct movements of this Endangered sub-population. These findings will guide conservation management and future research strategies in the Arabian Sea region.
