Smalltooth Sawfish in Florida and the Bahamas: Is there hope for this critically endangered species? - Dr. Dean Grubbs, Ph.D - FSU Coastal & Marine Lab

The sawfishes are a small group of large, formidable marine predators, but unfortunately they are also the most endangered of all groups of marine fishes. The smalltooth sawfish, which grows to more than 16 feet in length - making it among the largest coastal fishes in the world, was the first native marine fish listed as Endangered under the United States' Endangered Species Act. In the Northwest Atlantic the remaining smalltooth sawfish population is concentrated in southwest Florida and portions of the Bahamas. Unfortunately, very little was known about sawfish ecology, migration, growth rates or reproduction prior to the population declines, thus impeding recovery predictions. Over the past eight years, we have been using a variety of tracking techniques to uncover the mysteries of sawfish habitat use and movement patterns. We have also used a blood hormones and ultrasound to understand the reproductive biology of sawfish, recently discovering locations where mating and birthing take place. In addition to discussing these findings and the future for smalltooth sawfish in Florida, I will show a video from our work documenting for the first time ever, the birth of wild sawfish.
