Abstract: Assessments of demographic parameters are essential to understand the 
dynamics of wild populations, and for their efficient conservation and 
management. Here, sex-specific abundance, apparent survival and temporary 
emigration of southern Australian bottlenose dolphins (Tursiops cf. australis) 
in Coffin Bay (CB), South Australia, is investigated.  Results are based on 
capture–recapture modelling of photo-identification data and molecular analyses 
of biopsy samples collected during boat-based surveys between September 2013 
and October 2015 in the inner and outer areas of CB. The total super-population 
of dolphins (including calves) using the entire study area (263 km2) was 
estimated with POPAN models at 306 (95% CI: 291–323), which included 71 (68–73) 
marked females and 57 (55–60) marked males. Seasonal estimates of abundance for 
the inner area of CB (123 km2) obtained with Pollock's Closed Robust Design 
models remained relatively constant over the two years (marked females: 52–60, 
marked males: 46–52, and total: 193–209). The high density of dolphins 
inhabiting the inner area (seasonal range: 1.57–1.70 individuals km−2), high 
apparent survival rates estimated for both sexes (females: 0.99; 95% CI: 
0.96–1.0; males: 0.95; 0.82–0.99), and low temporary emigration rates (0.02; 
95% CI: 0.01–0.11) indicate that the inner area of CB offers highly favourable 
habitat for these dolphins.  High biological productivity and low predation 
risk may promote these demographic patterns in the inner area of CB. This study 
provides a robust baseline of sex-specific population demographics of southern 
Australian bottlenose dolphins with important implications for future research 
and their management and conservation in South Australia.
