Ecology and Population Estimates of Indo-Pacific Humpback Dolphins (Sousa chinensis) in Maputo Bay, Mozambique

The ecology and abundance of humpback dolphins inhabiting Maputo Bay were studied between December 1995 and December 1997 through boat-based surveys and photo-identification mark-recapture analysis. The sighting rate was low, corresponding to 21% of 146 surveys conducted. Estimated group size (mean=14.9 ± SD 7.32 individuals) was the largest reported for the eastern Africa region and did not change significantly with month, season, daylight, or tidal state. The proportion of individually marked adults was high among adults (0.52) and in a dolphin group (0.26). There is evidence for summer influxes of humpback dolphins into eastern Maputo Bay, and there are considerable numbers of apparently transient individuals.
