  1. Rescue and release stranded or trapped marine and freshwater mammals

    A study in 2003 in the Cachoeira River estuary, southern Bahia, Brazil (Batista et al. 2005) found that two stranded tucuxi dolphins Sotalia fluviatilis were successfully rescued and released. Two young, male tucuxi dolphins found trapped in a natural pool were successfully rescued and released in deep water nearby. Both dolphins were observed feeding within an hour of release and were not found re-stranded, although long-term survival was not reported. The dolphins were trapped within a natural pool (7 m deep x 50 m diameter) along a river for nine days. Nylon nets (120 m long x 6 m deep with 80 mm mesh) dragged by canoes were used to capture the dolphins in March 2003. Both dolphins were injected with a drug to prevent shock (4 mg of Dexamethasone), transported individually to the release site by a motorboat, and observed for 1 h after release.
