Scientists have discovered an unexpected surprise after the introduction of fishing green zones in more than 40% of the Great Barrier Reef since the 1980’s.

Every summer, tropical cyclones roll in from the east and reap their havoc on the reef. Turbulence and debris caused by the cyclones in Queensland decimate the states fish stocks, with Trout being particularly susceptible to this kind of environment. But thanks to the (now) long standing fishing green zones in place around the state, fish are growing to be larger, which means they’re more resilient to the cyclone conditions, and now surviving through it.

As you most likely know as a recreational angler, Green Zones are an effective ban on recreational and commercial fishing in a particular area. Chances are there’s a green zone near you, and while primarily implemented to prevent over-fishing, this latest study proves that additional benefits are only now becoming apparent.

Fish are growing to be larger than before, presumably due to living longer (because nobody can catch them) and breeding more effectively (due to being larger). With larger fish sizes, come a disproportional increase in eggs laid by female fish, for example a trout measuring 30cm might lay 800 eggs, when a trout measuring 60cm might lay 2400 eggs! Twice the size, three times the eggs can only be good for the fish stocks, and for you as a recreational angler as these little fish venture out of the green zones, and onto your hooks!

So remember, make sure you observe your local green zones because they actually help you in the long run!
