Presented By: Fish The Fly, Stonefly Nets, On DeMark Lodge, Visit Idaho. 

BoneFishing in Hawaii might not be the first thing that comes to mind when you think of saltwater adventures, but for Marine veteran Mike Bressler, it's become both a calling and a way of life. In this episode, we head to the island of Oahu to uncover what makes Hawaii’s flats fishery so unique—and so challenging. From bonefish (known locally as ō‘io) to golden trevally, Mike shares what it’s like to guide in one of the Pacific’s toughest but most rewarding destinations. Whether you’re planning a DIY trip or dreaming of landing a 10+ pound bone, his insights are packed with practical value.

We talk about everything from how to master casting in Hawaii’s relentless trade winds to how moon phases affect bonefish behavior. 
Mike also opens up about building his homegrown “Bone Lodge” for guests, the cultural realities of fishing in local waters, and why he takes veterans out monthly for healing on the flats. This episode is more than a fishing guide—it’s about patience, local respect, and finding purpose through saltwater fly fishing.

Notes with Mike Bressler on Bonefishing Hawaii

2:03 - Mike Bressler explains that while bonefish are active year-round in Hawaii, spring and summer bring peak action. The largest fish stay on the flats during the winter spawning season, starting around November’s full moon. Still, Hawaii is a tough fishery—constant trade winds and challenging conditions make it a true test for any angler. As Mike puts it, “If you can get good out here, you can be good anywhere.”

3:15 - Mike Bressler is based on the island of Oahu, Hawaii’s most visited island, known for its iconic Waikiki, but also home to quieter country towns like Hau‘ula, where Mike lives. He explains that bonefish—locally called ‘ō‘io (pronounced "oyo")—can be found all around the island, from beaches to flats. While flats fishing is preferred, Mike notes he has even spotted bonefish from the shoreline. In addition to bonefish, the waters also host various trevally species, including bluefin, golden, and the rare giant trevally, though bonefish remain the main attraction for visiting anglers.

5:46 - Retired Marine Mike Bressler discovered Oahu’s bonefish flats during a COVID quarantine on Ford Island. Now based in Hauʻula, he guides anglers year-round, with peak season from October to December. Windy conditions and remote flats make boat access and strong casting skills essential.

09:06 - Mike Bressler emphasizes that handling Hawaii’s wind starts with mastering the double haul and sidearm cast. He recommends aiming for at least a 40-foot cast under the wind and leading the bonefish, not landing the fly on their head. Sometimes, a short flip of the fly is all that's needed, as long as it's placed ahead of the fish's path.

9:49 - Mike Bressler explains that Hawaii’s largest bonefish are most active from October to December, as they begin their deep-water spawning cycle around full moons. He advises avoiding fishing three days before and after a full moon since fewer fish are found on the flats during that time.

12:29 - Mike Bressler and his wife host guests at their private rental, the Bone Lodge, a freestanding Airbnb-style unit that comfortably accommodates couples, small families, or fishing buddies. He offers customizable half-day and full-day guided trips, often using his 18-foot Kayo Boatworks skiff—weather permitting—to pole clients across the flats in search of bonefish.

16:36 - Mike Bressler explains that while fall offers peak conditions, big bonefish are still catchable in May. These “home guard” fish are older, resident fish that tend to stay shallow and fight with brute weight rather than long runs. Hawaii’s bonefish can reach impressive sizes—Mike has landed 12-pounders and knows of fish near 14, with the state record sitting at 15.7 lbs on conventional tackle. He also notes rumors of even larger bonefish—up to 20 pounds—coming from remote areas like New Caledonia.

18:17 - Mike Bressler shares that while bonefish populations are improving globally, Hawaii faces unique conservation challenges. Bonefish are considered a local delicacy, and with no regulations against harvesting them, locals often use nets or hook-and-line to catch them. Although enforcement is limited due to resource constraints, Mike hopes increased awareness will lead to better stewardship of the fishery.

20:51 - Mike Bressler starts most guided trips around 6:30–7:00 AM, timing for sunlight to spot fish while walking the flats and watching for signs of life like turtles or goatfish that indicate bonefish are nearby. Rather than tailing fish, anglers are taught to look for “Heineken backs”—a green shimmer just under the surface as bonefish move in with the incoming tide to feed.

24:31 - Mike Bressler shares that many first-time anglers struggle to spot bonefish, as their green shimmer is often mistaken for similarly colored reef fish. He recommends multi-day trips to learn proper sight-fishing technique—walking slowly, pausing often, and watching for subtle signs like nervous water, much like stalking prey in a hunt.

26:40 - Mike Bressler explains that while guiding, he positions himself based on the angler’s casting hand and wind direction, often spotting bonefish 10 to 50 feet—or even 50 yards—away. He coaches clients to observe the fish’s movement like a grazing animal, place the cast ahead of it, and use a slow strip to trigger a bite, reminding them never to trout set, but to keep stripping steadily for a clean hookup.

29:16 - Mike Bressler explains that a trout set often pulls the fly out of a bonefish’s mouth, while a strip set keeps the fly in the zone, allowing the fish to hook itself through steady tension. He adds that Papio, or juvenile trevally, sometimes rush in and steal the fly mid-strip, earning their nickname as “thieves” on the flats.

31:24 - Mike Bressler shares that while bonefish are the main target, golden trevally are considered the “unicorn” of Hawaiian flats—rare, elusive, and highly prized. Unlike their aggressive GT cousins, golden trevally feed on crabs, mantis shrimp, and baby octopus, making them a challenging and exciting catch that can grow to over 15 pounds.

32:53 - Mike Bressler emphasizes using a slow, smooth two-foot strip to keep the fly close to the bottom, imitating natural prey like crabs and mantis shrimp. He teaches anglers to let the fly sink fully, clear slack for direct connection, and make gentle, quiet adjustments—since bonefish, like snipers, will spook if prey behaves unnaturally or the line is moved too aggressively.

37:00 - Mike Bressler prefers a 12–14-foot leader built from 40-30-20 pound sections, finishing with a Rapala loop knot and adjusting to 16-pound tippet on calm days to reduce visibility. For gear, he recommends a 9-foot 8-weight rod paired with a sealed drag reel, 150 yards of backing, and Cortland’s Redfish Tropical fly line, which he trusts for its durability against coral-heavy flats.

39:46 - Mike Bressler prefers natural, flash-free flies for Hawaii’s bonefish, favoring subtle patterns like his variation of the “Spam and Eggs” fly, heavier Crazy Charlies, and shrimp-style flies made from materials like Arctic fox, raccoon, and EP fibers. He believes the key to success is imitating local prey like mantis shrimp and crabs, which have no reflective qualities, reinforcing his philosophy that “less is more” when it comes to fly materials.

43:08 - Mike Bressler shares that the most effective fly colors for Hawaiian bonefish are browns, tans, blacks, and occasionally a translucent orange, matching the natural hues of local mantis shrimp on the flats. While some mantis shrimp in other regions show vibrant rainbow-like colors, Mike notes that the shrimp in Hawaii’s flats are smaller, subtler, and adapted to their muted, sandy environment, reinforcing the importance of natural tones when fly tying.

44:59 - Mike Bressler advises that while Oahu is ideal for DIY bonefishing with walkable flats and public shoreline access, islands like Moloka‘i should be approached cautiously due to cultural sensitivities—locals may challenge visitors fishing near their homes. For Maui or Kaua‘i, DIY anglers should use satellite imagery to identify promising flats and focus on incoming tides, which provide better access and more time on the water without needing a boat. Enjoy a breathtaking view of Moloka‘i.

48:35 - Mike Bressler notes that while bonefish are present on the Big Island, it’s the one place in Hawaii he hasn’t personally landed one, and he primarily guides out of Oahu, where conditions and access are more reliable. He encourages anglers to book at least a half-day with a guide—not just for learning spots, but to understand the local waters, tides, and fishery culture—emphasizing that for him, guiding is a passion rather than a livelihood, unlike many full-time guides who depend on it to make ends meet.

51:21 - Mike Bressler highlights a major step forward in Hawaiian conservation with the new non-resident fishing license requirement, which began in April and helps fund efforts like coral restoration through DLNR. While no major bonefish-specific conservation group currently operates in Hawaii, Mike stresses the importance of ethical fish handling, reef awareness, and hopes for future support from organizations like Bonefish & Tarpon Trust to expand research and protection efforts in the islands.

55:04 - Mike Bressler reflects on the historical weight of living and guiding near Pearl Harbor, noting its deep connection to his 24 years of service in the Marine Corps. As part of giving back, he offers free monthly guided fly fishing trips to fellow veterans, believing strongly in the mental clarity and healing that comes from time on the water—something he says benefits anyone going through stress, not just those who’ve served.

59:20 - As the episode wraps up, Mike Bressler offers heartfelt encouragement to new and seasoned anglers alike, reminding them that the real reward in Hawaii isn’t just the bonefish but the experience of being on the water in such a stunning place. He expresses support for Project Healing Waters, offers to help veterans get out and fish, and leaves listeners with a simple message: come out, enjoy the island, and if you catch a fish, that’s just the bonus.

Top 8 Bonefishing Tips from Hawaii Guide Mike Bressler

1.  Hawaii’s constant trade winds make it essential to learn the double haul and sidearm casting techniques to effectively reach bonefish in tough conditions.

2.  Approach the flats like a hunter—move slowly, pause often, and avoid sudden steps that could alert fish via vibrations in the water.

3. Bonefish in Hawaii often appear as a glowing green shape, like a Heineken bottle, moving through the water. Training your eyes to spot them is key.

4. Mike recommends fly patterns with no flash, using natural materials like Arctic fox, raccoon, and EP fibers to mimic mantis shrimp and crabs.

5. Strip Set—Never Trout Set. When a bonefish eats, maintain a steady, long strip to hook the fish. Lifting the rod (a trout set) often pulls the fly right out of their mouth.

6. Mike’s go-to leader build includes 40-30-20 pound sections, prioritizing strength to manage coral-heavy flats and powerful runs from big fish.
