  1. Rehabilitate and release injured, sick or weak marine and freshwater mammals

    A study in 1999–2000 of a pelagic area in the Gulf of Maine, USA (Nawojchik et al. 2003) found that two stranded juvenile long-finned pilot whales Globicephala melas that were rehabilitated and released back into the wild survived for at least four months. The two rehabilitated male whales were successfully tracked for 127–132 days after release back into the wild. During that time, they travelled at least 3,790 km at average speeds of 23–66 km/day. Tracking positions suggest that the two whales remained together after release. The two juvenile whales (220 and 313 cm long) were found stranded on a beach in June 1999 and taken to a rehabilitation facility. They were housed in a pool and fed herring (average 25 kg/day). After four months of rehabilitation, both whales were fitted with satellite-linked time-depth recorders and released at sea in October 1999. They were recorded at 329–386 locations during 127–132 days between October 1999 and February 2000.
