Comparison Of Group Size, Abundance Estimates And Movement Patterns Of Common Bottlenose Dolphins (Tursiops Truncatus) In Mississippi Sound, Mississippi, Carrie Sinclair

LSU Master's Theses

Common bottlenose dolphins (Tursiops truncatus; dolphins) inhabiting Mississippi Sound (MSS) in the north-central Gulf of Mexico (GMx) are considered a part of a single stock of dolphins that includes Bay Boudreau and Lake Borgne by the National Marine Fisheries Service (NMFS). MSS is bounded by the mainland (north) and several barrier islands (south). Dolphins inhabiting coastal waters directly south of the barrier islands constitute part of the Northern Coastal Stock. Abundance in MSS has been reported to fluctuate seasonally, with higher abundances of dolphins estimated in summer versus winter. Analysis of covariance was used to compare previous abundance estimates. Results …
