Survey/Project Number: 1120          Total No. of Sites: 1
Survey/Project Name: Behavioural ecology of dolphins summary dataset -Adelaide Dolphin Sanctuary
Abstract: This project aims to summarise records collected by BDBSA Project 1121 in the Adelaide Dolphin Sanctuary (ADS), near Adelaide, South Australia. The work is part of a long-term research project which commenced in 1988 and is ongoing. OBJECTIVES: 1. Document the lives of dolphins and other species in the research area; 2. Monitor morbidity and fecundity; population levels; habitat use; 3. Monitor anthropogenic impacts on the animals. METHODOLGY: Data is gathered in the ADS primarily from a 6-metre research vessel and is in accord with the approach distances legislated for the general public. Data is collected on the environmental characteristics of local habitats. Observational and photographic data collected on dolphins is date, time and location of sightings; number and demographic composition of animals sighted; and behaviour. Observations are also made of the physical condition of animals to monitor health, entanglements, etc. Observations on Pinniped-numbers in the Port River estuary have also been made, and this data is being prepared for publication. Incidental observations on sea birds and other marine animals are also collected. Data obtained from this research project was used to establish the boundaries of the ADS. Observations on health status of animals has led to successful interventions to undertake disentanglements. Overall population monitoring has revealed that dolphin numbers in the inner parts of the ADS are increasing. The research has led to a general increase in community awareness of these dolphins. The research has also documented the emergence of a cultural behaviour (tail walking) in this community of dolphins. The research has produced information which has been useful for local tourism operators. Marine litter is collected whenever possible.
