Mark Quartiano, known to the fishing world as Mark the Shark, is one of the most recognizable and controversial big-game fishermen to ever run charters out of Miami. On this episode of the Tom Rowland Podcast, he tells me how he built one of the most notorious names in sport fishing, what decades of chasing giant sharks taught him about the ocean, and how the sport and the public conversation around it have changed. It is a raw look at a career spent at the extreme edge of saltwater fishing.
Mark the Shark is the nickname of Mark Quartiano, a Miami-based big-game charter captain who became one of the most famous and most debated shark fishermen in the sport. He built a public profile over decades of targeting large sharks and other big-game species off South Florida.
Quartiano describes building his name through years of high-profile charters, media attention, and a willingness to chase the biggest fish in the ocean. The Mark the Shark brand grew alongside the spectacle of landing enormous sharks out of Miami.
Shark fishing sits at the center of a long debate about conservation, and Quartiano has been a lightning rod in that conversation. On the show he addresses the criticism his career has drawn and how attitudes toward shark fishing have shifted over the years.
His reputation is built on giant sharks, but Quartiano has spent a lifetime as a big-game charter captain pursuing the largest and most powerful fish that swim off South Florida. He talks through the gear, the conditions, and the chaos of fighting that caliber of fish.
Quartiano made his name running charters out of Miami, fishing the waters off South Florida where big sharks and other large pelagic species can be found close to one of the busiest coastlines in the country.
Quartiano reflects on how the sport, the regulations, and public sentiment around shark fishing have evolved across his career, and what that has meant for someone whose whole identity is tied to it.
Mark the Shark is one of those names that anyone who has spent time around saltwater fishing recognizes immediately, and I have always been curious about the person behind the persona. He has lived at the most extreme end of big-game fishing for decades, and he has taken plenty of heat for it. I wanted to hear his story in his own words, the building of the name, the reality of the work, and how he sees the sport now, without filtering it through anyone else's outrage.
A nickname like his does not happen by accident. Quartiano walks me through the years of charters, attention, and outsized catches that turned a Miami captain into a brand people recognize on sight. The story is part hustle, part spectacle, and part pure obsession with the biggest fish in the water. Listen to how the legend actually got built.
There is a world of difference between hooking a fish and landing one that can outweigh the people on the boat. Quartiano describes the physical reality of chasing that caliber of animal, the gear it takes, and the moments that have stayed with him. Hear him take you inside the fight in the episode.
Few topics in fishing are as charged as shark fishing, and Quartiano has been at the center of that storm for years. He does not dodge it on the show, talking through the criticism and how he thinks about his place in a changing conversation. Press play to hear how he answers his critics.
The rules, the technology, and the public mood around big-game and shark fishing all look different than they did when Quartiano started. He reflects on what has shifted and what it means to keep doing this work as the world around it changes. Listen to his read on where the sport is headed.
The day after this conversation, what stayed with me was how singular a path Quartiano has carved. Whatever you think about shark fishing, the man has lived his whole life pointed at one thing, and he has never softened the edges to make it easier to swallow.
The bigger takeaway for me is that these conversations are worth having directly. It is easy to have an opinion about a figure like Mark the Shark from a distance. It is more interesting to actually hear him out.
Listen to the whole thing. It is one of the more unforgettable characters I have had on.
