The Reef Guardian Fisher program was initially rolled out by the Great Barrier Reef Marine Park Authority and it was originally designed to get the traditional type of commercial fishermen to publicly display and advertise sustainable methods of catching fish and harvesting large quantities of fish, which in turn creates awareness for the general public.
However, it’s now also for the knowledge of commercial fishermen. We consider ourselves commercial fishermen – or I do personally – and I feel a sense of responsibility to spread the news about sustainable practices. We're the only charter company to be a part of the Reef Guardian Fisher program and we teach other commercial fishermen that even if you don't have a net, there are ways you can sustainably take out people and catch fish day after day.
You offer sportfishing tours that practice predominately catch and release – what are the benefits of this approach?
As mentioned, we offer saltwater fly fishing, which means we specialise in catching fish on top water (targeting the fish in shallow water). So, in one of our experiences, you'll walk around in really shallow water to target fish, and then you’ll also throw lures on the surface of the water to get their attention.
However, if you’re bottom fishing and you drop a bait or a lure down to 30 or 50 metres and hook a fish, many things happen that determine whether that fish survives or not, including a thing called barotrauma. If the fish is hooked down deep, certain species suffer from it more than others. Traditionally, the demersal fish or the bottom-dwelling fish suffer quite heavily from it as the stress from being hooked means they don't have the time to change or equalise their swim bladder, so as they ascend at a rapid rate, their swim bladder expands and causes barotrauma – which essentially puts pressure on their internal organs and causes them to rupture.
So, if you’re bottom fishing and bring up a fish, and it's a protected species, usually it's dead anyway, so you're affecting the overall biomass of that species just by bottom fishing. And if it's undersized, you have to let it go, but it's dead anyway, so again, you're affecting the biomass of that species.
Another thing with bottom fishing is going to the same bottom fishing spots day in and day out. There's a school of fish there just milling around, doing their thing, and when you drop a bunch of baits down, it causes a big chum line or a smell line, which not only attracts the fish but also attracts sharks. When you hook these fish, it causes them to be eaten by sharks. More sharks are a hot topic at the moment amongst bait fishermen, but in my opinion, the shark problem is being contributed to and amplified by bottom fishing. Sharks learn like puppy dogs do, so if these bottom fishing boats go to the same spots every day and drop their anchor down, the sharks will hear that chain go down, arrive, wait for the bait line, smell the bait, get excited and then there's all these fish in distress which then get eaten. Yet we don't see as many sharks because we're fishing with lures that don't have a scent.
We also don't anchor when we go to a reef edge as we're constantly moving. Even though the fish come up to the surface and eat, our lure is coming up in his natural hunting environment, so there's no barotrauma. He's not distressed before he comes to bite the lure. In fact, he's in complete natural hunting mode and will swim up to the surface and grab your lure, and then you're on. So not only is saltwater fishing a visual type of fishing, but it also allows you to successfully release the fish afterwards.
Growing up, I remember my dad said to me, “You should have seen the fishing when I was younger”, and I don’t want to say that to my son when he's older, so I feel it’s my responsibility to do what I can to ensure the fishing is as good as it is now when he's older and we're all responsible for working on our ocean to make sure that happens.
