TRCP’s “In the Arena” series highlights the individual voices of hunters and anglers who, as Theodore Roosevelt so famously said, strive valiantly in the worthy cause of conservation.

Conservation credentials: Diaz harnesses his adventurous fishing spirit, a gift for outdoor photography, and a prominent platform on social media to advocate for marine conservation, inspiring and helping educate saltwater anglers.
Besides sharing his captivating shots of recreational fishing feats with conservation groups like TRCP and Safeguard the Seas, Diaz has donated his breathtaking underwater shots of striped bass to the Bayshore Saltwater Flyrodders of New Jersey and has been invited to speak at several fly fishing clubs in New York and New Jersey, where he focuses on the importance of safer catch and release practices. Diaz volunteers for the Manhattan Cup, a fishing tournament in New York City that benefits veterans, to shoot photos and video. Currently, he’s working with TRCP partner Bonefish & Tarpon Trust to plan a trip to document the planting of mangroves and habitat restoration in the Bahamas or Caribbean.
Here is his story.

Some of my earliest memories are from when I lived in the state of Tabasco, Mexico. My father was a military officer in the army, and during those years, the local fisheries were incredibly abundant. We had easy access to rivers and a coastline full of tarpon, snook, tropical gar, and jacks. It wasn’t unusual to see all of those species in a single morning.
Those early experiences with my father, learning how to cast and being immersed in such a diverse ecosystem (so yes, full of biting insects), left a lasting impression on me. They taught me to value wild places and understand the importance of protecting them, especially because, back then, conservation wasn’t practiced the way we know it today.

Over the years, I’ve had the opportunity to experience incredible moments on the water. Recently, while wading the flats of Inagua, Bahamas, looking for bonefish, I spotted something large floating almost motionless along a channel. As I got closer, I realized it was a big barracuda, perfectly still and clearly waiting to ambush prey.
Hoping for a shot at this trophy fish, I quickly clipped my leader, tied on wire, and rigged a large white deceiver fly to try and trigger a strike. Luckily, the barracuda was still holding in place by the time I was ready. On my second cast, she hit so fast I barely saw it happen.
I fought her in the shallow flat, where I could truly appreciate her size and watch her leap into the air several times. An amazing fish—and a moment I won’t forget.

There are so many remote angling destinations still on my list. But if I could fish anywhere, I’d have to say I’d go back to Hawaii to wade for big bonefish. The first time I visited was on my honeymoon, and while fishing wasn’t exactly on the itinerary, I couldn’t help but notice bonefish cruising the flats and hear talk of people targeting them. At the time, I had to let it go, but ever since, the idea of returning has stuck with me, especially after seeing videos of those massive fish. Hawaii is home to some of the biggest bonefish in the world, and the thought of sight fishing for them in such a stunning, remote setting is just too good to resist.
“Being involved in conservation means protecting the waters, habitats, and species we rely on, so the fish are still there tomorrow.“
Conservation is at the heart of my fishing life because the health of the resource is everything. I love everything about fishing – not just catching fish, but the whole experience of being involved in nature, reading the water, and connecting with wild places. Without healthy ecosystems and abundant fish populations, that experience simply wouldn’t exist.
Overfishing and water quality are the biggest conservation challenges where I live in coastal New York. Pressure from recreational and commercial fishing has led to reduced populations of key species like striped bass. A critical part of addressing this is the need to conserve menhaden, commonly known where I live as “bunker,” as an essential forage fish that striped bass and other gamefish species depend on for food. At the same time, water quality degradation from nitrogen pollution, mainly due to septic systems and runoff, continues to destroy habitats and create aquatic dead zones.

Conservation ensures that the waters I fish today will still be there tomorrow, full of life and possibility. It’s about respecting the resource, practicing catch and release when appropriate, and supporting efforts that protect habitats and biodiversity. For me, being a responsible angler goes hand in hand with being a good steward of the places I love.
I feel compelled to do my part in conservation because I want the next generation to experience the same connection to fishing that I’ve been lucky to have. Fishing isn’t just a pastime. It teaches respect for the environment and shows the value of healthy ecosystems. Being involved in conservation means protecting the waters, habitats, and species we rely on, so the fish are still there tomorrow, not just today. It’s about giving back to a resource that’s given me so much.

If we don’t take care of the land and water now, there won’t be anything left to hunt or fish later. Conservation helps to keep the traditions alive – the early mornings on the water, the stories, the connection to nature. If we want to continue to enjoy the outdoors, we have to protect them.
