When somebody says they just want to go fishing and get punished by something big and strong, the one fish that pops into my head is the Gangster of the ocean, the Giant Trevally.
Because they can PULL!
For years many anglers thought the only way to catch them was with poppers thrown around isolated bommies, but over the years other methods have come to light.
In this blog I’m going to go through a few methods I’ve used to catch Giant Trevally in north Queensland, but these techniques will work equally well elsewhere.
Casting poppers for GT (Giant Trevally)
Firstly let’s start with the old traditional way casting poppers as I have previously mentioned. Now this method only works at certain times and like many pelagics you need current to get them to come to the surface.
Because they simply love chasing a moving target blooping on the surface.
Although the best time for this is on the larger making tides up to the moons and even then only while the tide is running.
A rocky outcrop or fringing coral ledge scattered with coral bommies is the best location.
Simply work these edges or outcrops using big poppers and a heavy duty spin outfit with a good retrieval rate because they like it fast. However an overhead outfit is useless in this situation as you can’t get the casting distance nor the fast retrieve to get those poppers blooping.
Once you have found a few fish willing to follow, work that area for a while and you should come up with the goods. Sometimes you’ll be stuck with what seems like a never ending bite resulting in very sore arms. But as soon as the tidal run slows towards the change of tides, this style of fishing slows down.
Another method of targeting them on the surface is to find isolated wrecks or structure. Troll those large poppers over it and once again this must be done with tidal flow.
Some beautiful poppers are being made by Dave Killalea’s Old Dog Lures which are suited to trolling and casting. I can’t wait to give them a try.
Giant Trevally on the fly
On occasions in areas of less pressure we have seen massive schools in the shallows. They even resemble bommies they are so thick. We witnessed this several times up around Lizard island while fly fishing for them.
In excitement we would troll the fringing reefs with poppers that have no hooks and the client would stand at the ready with his fly rod. We would tease them up to the back of the boat as they were smashing the lures. And then when close enough the angler would drop his fly in front of them. It was not a matter of one taking the fly but which one got to it first.
I can remember on 3 occasions that GTs were so thick climbing over the popper teasers that they would woof it down and shoot out their gill openings. It would then wrap around their head and lasso them. Was amazing to watch let me tell you.
Dropping metal slices to catch Giant Trevally
So what happens when the tidal flow stops or the tides become neap? This is when the fish retreat to the depths and hang around at or near the bottom.
You will still find them in the same vicinity as the outcrops etc., but they will be out on the deeper drop offs.
When they get into this mood the best method to use is dropping metal slices to the bottom and then a very fast retrieve all the way to the surface.
There is something about a small shiny object getting ripped vertically past them that they just can’t seem to ignore. It must ignite a kind of feeding ritual they have inbuilt into them. If you drag the lure horizontally past them they will ignore but vertically just makes them fire up.

Using soft vibes and plastics
Using soft vibes and plastics in this manner will also work and we have proven that on several trips. It’s the same as a metal slice just drop the plastic to the bottom and retrieve.
Now let me say that they are only a sport fish as their eating quality is poor and they are very hardy and generally release well.
GT’s can be targeted in the fin fish closure
And we recently had some fun slow pitch jigging for GT’s in the fin fish closure. Click here to watch the video.
Releasing Giant Trevally
The best way to release after a quick photo is by spearing them head first into the ocean to get that rush of fresh oxygen flowing over the gills. This is a requirement for all pelagic species as they are designed for faster and constant swimming as compared to a barra that spends a lot of its time hovering in one spot. When we release fish such as barra we simply put them in the water and hold them in an upright position until they regain their composure.
So in conclusion make sure your tackle is up to the task and you’ve eaten your Wheaties that morning as a big sesh on the GTs is going to sort out the men from the boys.
Just think of the exercise as your biceps will be bulging before you know it.
