    Core Angling: Science and Fly Fishing Combined

    [Update: Added a bunch of photos after the jump.] Patagonia Fly Fishing Marketer, Bill Klyn, shares his experience with a new kind of fly fishing trip. Core Angling offers world-class bonefishing in the Bahamas combined with the opportunity to help scientists study the fish and hopefully preserve their numbers for good. If you're an angler, or you know one, be sure and check out the fish-landing tips at the end of his story.

    Bonefishing: Just the word elicits that memory of blistering sun, wading sand and marl flats of soothingly warm calf-high water, that smell of primordial ooze, while constantly searching for that tailing fish, nervous water or that dark shape that suddenly appears – usually at the last minute before spooking. That memorable cast that gently lays the fly close enough to see that exciting, accelerated grab, then the sound of the screaming reel during that zip code changing run that elevates both the heart rate and one’s soul. What can be better than that?

    Having run into Bonefish Tarpon Unlimited’s Director Aaron Adams at the Somerset Fly Fishing Show, he introduced me to Dave Peterson representing a group called Core Angling. This new take on bonefishing allows anglers to join scientists with the challenging job of catching fish that become live “samples” for research to help fill the significant gap in knowledge of bonefish spawning, predation and habitat. With this taking place in the remote location of Eleuthera, Bahamas, my only question was, "Where do I sign up?"

    Gathering a group of reps from Patagonia – Mike Thompson, Mark Harbaugh and Jason Lozano – we arrived in Eleuthera to be met by Dave Peterson and the Director of Cape Eleuthera Institute, Andy Danylchuk. As it turns out, Andy is the Lefty Kreh, the Babe Ruth of bonefish scientists in the Bahamas.

    Feeling like seven-year-olds, wading the flats took on a new perspective of wonder and learning experience, even though it was something our group had been involved in for many years. Andy and Dave, like the patient fathers, readily fielded every question from our thought-to-be-knowledgeable group. But when that first fish was caught and out came the research equipment, our interest took a fundamental shift from angling to research.

    The process of studying recovery rates of fish was such: after measurements and fin clips were taken, a freshwater hook with mono line and bobber was attached to the dorsal fin. The freshwater hook would rust-out rapidly if we could not retrieve the bobber. We could watch that bobber for 20 minutes until the fish was totally recovered, or shorter if shark or barracuda had the fish for lunch. What fly fisherman had ever been interested in watching a bobber, unless attached to a dead-drifting nymph, for 20 straight minutes? Well, watching that bobber as it would head back with the school or beat fins to deeper water, became a mesmerizing experience. Realizing the average time an angler spent taking “a hero shot” – just a minute – the recovery rates plunged, primarily to predation. Conversely, the less time out of water, there was a higher percentage of recovery.

    The other study we did was to place a fish in a live well for 20 minutes and the researcher would test the water every five minutes to determine the chemical secretions of the fish. This helped to determine what secreted chemicals excited the predators to target the fish.

    Finally, we were going to known areas that fish with transmitters were frequenting. Dropping a portable receiver over the side of the boat to listen for any “pinging,” we were able to catch up with Andy on what the research was providing.

    Heading to the Eleuthera Institute and seeing the many tanks and testing facilities on bonefish and sharks, speaking to other scientists, and hearing of impending studies for the future, instilled an even greater interest to come back once again for the next round of research.

    Did I mention that the waters just off the Institute dropped to 1,000 feet a few miles from the harbor? And that dorado, sailfish, sharks and other offshore species can easily be reached in a very shot run?

    We found a way that was better than just fishing. Whether you're a seasoned bonefish junkie or new salt water angler, I highly recommend taking a trip with the Core Angling folks to enhance your experience. Create a new memory and support further research by joining Core Angling (866-207-1891) and the Cape Eleuthera Institute. Or if you want to do something now to support saltwater flats research, check out Bonefish Tarpon Unlimited and the terrific work they are doing.

    Tips from our collective experience:

    • Release a fish in the water.
    • If the fish is still fighting with you, hold them upside down and they will stop for quick removal of the hook.
    • If you have to take a picture of a fish, have everything ready – camera, glasses off, etc. Then wet your hands, pick up the fish and take the picture in seconds (run around until you are exhausted, hold your breath, then figure out how long that is for you).
    • Do not use a lip-gripping device on a bonefish as their soft mouth and jaws have a great deal of trouble handling that much pressure.
    • Plan a trip with consideration of the new moon. This is when fish “disappear” in large numbers to spawn.
