Formatted Abstract/Summary
The dugong (Dugong dugon) is a vulnerable marine mammal with large populations living in urban Queensland waters. A mark-recapture program for wild dugongs has been on-going in southeast Queensland since 2000. This program has involved capture and in-water sampling of more than 800 dugongs where animals are held at the water surface for 5 minutes to be gene-tagged, measured and biopsied. Recently, this program has expanded to examine more comprehensively body condition, reproductive status and health of wild dugongs in Moreton Bay. With the assistance of Sea World, captured dugongs were lifted out of the water onboard a research vessel to collect accurate body weights and morphometrics, obtain blood and urine samples for baseline health parameters and hormone profiles, and ultrasound females for pregnancy status. In all, thirteen animals including two pregnant females were sampled over five days and restrained on deck for up to 50 mins each whilst biological data were collected. Each of the dugongs had their basic THR (temperature - heart rate - respiration) monitored throughout their period of handling, following protocols developed for the West Indian manatee. This paper reports on this out-of-water operation and the preliminary results obtained including physiological response of captured dugongs as indicated by their vital signs, and the suitability of the ‘manatee’ monitoring protocols to this related species.
