On the last weekend of the 2017/18 wild brown trout season for Tasmania, temperatures had dropped in the highlands so we decided on a day at Four Springs. With hardly any surface food there weren’t many rises, so we got stuck into it with a nymph under the emerger. Jon landed this well conditioned hen rainbow.
A quick trout food report for you.
In the northern lowlands good volumes of flying ants are starting to appear in clouds around the trees on days of light winds.
Grasshoppers are still on the menu on many lowland rivers.
Jassids have been around now for a couple weeks in the central highlands and sighted at many popular waters.
This image shows a lowland jassids of a similar variety to the highland jassids that are currently exploding in populations this year.
The key with jassids and the fly pattern is the underneath needs to show a good amount of bright red, and the fly should be fished static.
Jassid, like many insects, go through stages of maturity called instars. These jassids have not yet developed their wing cases, exposing their true under body colour.
During extremely hot conditions in Tasmania, it’s well worth giving thought to cooler rivers, streams, and tributaries. And they would be tail race rivers such as Brumbys Creek and the Meander River. Also, depending on flow, the Upper North and South Esk Rivers and their tributaries, just to name a few.
We decided to explore the Upper Mersey River in the Mersey Forest area. Water temperatures were a lovely 16 degrees Celsius, and the wild browns and rainbows were feeding without too much stress or hesitation.
Small mayfly patterns along with grasshopper patterns in some areas did the trick.
This gorgeous wild brown trout was caught and released, on a 4 weight with a grasshopper.
