Collaborative Rescue Team

For the second time in three weeks a young dolphin is swimming free of fishing line thanks to the efforts of a rescue team involving collaborating organizations from up and down Florida’s west coast."

During a routine field survey in February, biologists from the Chicago Zoological Society’s Sarasota Dolphin Research Program (SDRP) noticed a 2-year-old male dolphin looking underweight. A month later, the animal looked even skinnier and had fishing line deeply embedded in his tail.

Upon approval by NOAA’s National Marine Fisheries Service, SDRP mobilized a rescue team to catch the dolphin, remove the gear, look at the animal’s overall health, treat it as necessary, and release the dolphin back into its natural habitat. This kind of rescue effort requires a lot of resources; in this case eight boats and 48 people, including veterinary staff, biologists, and trained dolphin handlers.

The rescue team sighted the dolphin soon after leaving the dock. It was alone, having separated from its mother over the past few weeks. Within 20 minutes, the team was able to encircle it with a net in shallow water and begin line removal and treatment, including an antibiotic shot. The monofilament fishing line, with the added drag from algae and tunicates, had cut 85 percent of the way through the right tail fluke. With every tail beat, the line was cutting further and further through the tail. After successfully freeing the line from the young dolphin, he swam away strongly.

The rescue was conducted under a NOAA permit, and led by the Chicago Zoological Society's Sarasota Dolphin Research Program working in collaboration with partners, including Mote Marine Laboratory, the Florida Fish and Wildlife Conservation Commission, the University of Florida’s College of Veterinary Medicine, Clearwater Marine Aquarium and National Marine Fisheries Service’s Southeast Region Office.

In the following weeks, SDRP biologists will continue to go out and monitor the calf's progress. Because this was the second disentanglement of a young dolphin from fishing line in only three weeks along the central west coast of Florida, scientists and wildlife management officials are concerned that the decline in fish stocks from the recent severe red tide may be bringing mother dolphins into closer contact with anglers. This has the potential to create situations where their young, naive calves can become entangled in fishing gear. Anglers are urged to be cautious if dolphins appear, and to reel in their lines until the dolphins leave.

The best way to help marine life in trouble is to call trained responders, report your location and wait near the animal. Please call 1-877-WHALE HELP to report injured or dead marine life or use NOAA's Dolphin and Whale 911 phone app.
The rescue was conducted under NOAA permit 18786-03.
