Seven calves have been born to the SDRP community residents so far this season; one of these has disappeared and is presumed to have died. Over the years, we have found that about 70-80% of Sarasota Bay calves survive their first year.
Ten-times per month dolphin photographic identification surveys continued. (That’s where we keep track of the calves.)
Seasonal fish surveys continued, finding average numbers of dolphin prey fish for this time of year in the bay.
At the request of NOAA, we led a successful capture-release rescue effort on 4 September near Marco Island, FL, to remove fishing gear from the tail of a yearling calf, nick-named “Skipper”. The wire leader was embedding in the tissue of the tail stock and fluke. This calf was the younger sister of a dolphin nicknamed “Seymour” that had to be rescued due to a similar entanglement in 2012. Subsequent to the rescue, Skipper and her mother have been observed engaged in typical activities.
We continue tracking a dolphin nicknamed “Speedy” we helped to rescue in the Everglades on 31 July, the first data collected on movement patterns of dolphins in the Everglades. Speedy is using a variety of habitats, including creeks, the waters surrounding the Ten Thousand Islands, and Gulf of Mexico coastal waters.
We continue tracking 11 bottlenose dolphins tagged with satellite-linked transmitters in Barataria Bay, Louisiana, in June as part of the 2014 dolphin health assessment associated with the Deepwater Horizon oil spill investigation. As in previous years, the dolphins are staying within a localized area, suggesting a definable home range.
