The Tom Rowland Podcast interview with Chris Fischer is a conversation about how OCEARCH, the nonprofit Fischer founded, transformed great white shark research through open-source tagging and real-time tracking. Working with Captain Brett McBride, Fischer developed techniques to safely catch and study massive white sharks after starting his career hosting the show Offshore Adventures. The conversation traces OCEARCH's origin, the shark named Mary Lee who saved the organization from bankruptcy, and why more sharks off Florida's coast signal a healing ecosystem rather than a crisis.

OCEARCH is a nonprofit organization founded by Chris Fischer that tags and tracks great white sharks and other apex predators using an open-source research platform. The organization conducts 25 different research projects on every shark they tag, working with 49 researchers from different institutions.
Chris Fischer is the founder of OCEARCH and creator of the show Offshore Adventures. He started in billfish research before transitioning to white shark conservation after a scientist told him that with only 9% of large sharks remaining, fixing the shark population was critical to saving all fish populations.
OCEARCH uses a technique developed by Captain Brett McBride that leverages a concept called learned helplessness. Once a shark takes the bait, the team uses precisely sequenced buoys to guide it toward the ship's hydraulic lift platform, catching thousand-pound sharks in as little as six minutes and 4,000-pound sharks in sixteen minutes without harming the animal.
The Global Shark Tracker is an open-source platform launched by Chris Fischer in 2012 that lets the public follow tagged sharks in real time. Every time a tagged shark's dorsal fin breaks the surface, it pings a satellite and the location appears on the tracker.
According to Chris Fischer, the sharks anglers are seeing indicate ecosystem recovery, not overpopulation. OCEARCH's research found that Florida's Eastern Seaboard between Hatteras and Canaveral is the primary winter habitat for white sharks, and more sharks means more of everything is thriving.
Captain Brett McBride is the fishing captain who has worked with Chris Fischer since the beginning of OCEARCH. Fischer calls McBride the single most underappreciated person in the white shark research space, crediting him with the catching innovations that made the program possible.
Mary Lee was a white shark OCEARCH tagged in Massachusetts in 2012 that Fischer named after his mother. She swam down the entire East Coast, appearing on the Global Shark Tracker in nearly every major bay and estuary, and the public attention she generated saved OCEARCH from bankruptcy.
I've known Chris Fischer for years through his work with OCEARCH, and I've always been amazed by what he and Captain Brett McBride have accomplished. This conversation was a chance to hear how the real accomplishment isn't just tagging great white sharks — it's building the bridge between anglers and scientists.
Chris Fischer didn't set out to become the world's leading white shark researcher. He started with a show called Offshore Adventures, focused on billfish and the fishing lifestyle. But when a scientist told him we're down to just 9% of our large sharks, everything changed. The full story of how OCEARCH was born is worth hearing in his own words.
When Fischer and Captain Brett McBride first attempted to catch massive white sharks for tagging, they were unprepared for what they faced. The breakthrough came through the discovery of learned helplessness, which took capture time from an hour down to sixteen minutes. Press play to hear Fischer describe it as one of the most underappreciated innovations in the entire operation.
In 2012, Fischer launched the Global Shark Tracker with the last half-million dollars from his TV work. He tagged a shark and named her Mary Lee after his mother, thinking she'd be the last shark they'd ever touch. What happened next is one of the most compelling parts of this conversation.
Tom asks Fischer the question every Florida angler wants answered: why are there so many sharks now? Fischer's answer reframes the entire conversation, and it's worth hearing directly from him.

I've known Chris Fischer for years through his work with OCEARCH, and I've always been amazed by what he and Captain Brett McBride have accomplished. But this conversation revealed something I hadn't fully appreciated: the real accomplishment isn't just tagging great white sharks. It's building the bridge between anglers and scientists, creating an educational platform that reaches millions of people, and developing a replicable model for ocean conservation.
What Chris says about Florida's shark population is something every angler needs to hear. The ecosystem is healing. The sharks aren't the problem — they're proof that things are working the way they should.
The Mary Lee story alone makes this episode worth listening to, but the deeper conversation about bringing anglers and scientists together is what stuck with me. Press play above and listen to the whole thing.
