Tracking shark populations, one shark at a time

About 130 days a year, a research vessel leaves Miami and sets out to catch, measure, sample, tag, and release sharks in Florida’s coastal waters. Over the course of a year, they’ll encounter about 600 animals in a process called “fisheries independent monitoring,” an effort to gather data on sea creatures that isn’t skewed by changes in fishing procedures, equipment, or regulations.  Marine conservation biologist Catherine Macdonald leads the lab behind that effort. She joins Host Flora Lichtman to talk about shark conservation, share stories from her research, and spread shark joy.  Guest: Dr. Catherine Macdonald is a marine conservation biologist and director of the Shark Research and Conservation Program, part of the Rosenstiel School of Marine, Atmospheric, and Earth Science at the University of Miami.
