Here is the overview of the hatchery works over the last few weeks; All our eggs for the 17-18 stocking season have been laid down and the trap has been taken out as of the 30th August. Although the spawning run started late due toa lack of water and rain events, the Browns ran really well, with 2247 individuals recorded before the trap was taken out, and more still in the system near the hatchery. 400000 eggs have been laid down at Gaden , with another 600000 set aside for Dutton Hatchery. We have about 300,000 wild RT eggs laid down for the Jindabyne and Eucumbene allocation, and 800,000 eggs from our 2+ and 3+ broodstock, which have all been mixed with wild males. The trapped Rainbow count for the year was 366 individuals, with many more seen after the trap was taken out. About 25000 rainbow trout eggs were collected from Hughes and Tolbar creeks in the Eucumbene system on the 31st August. Once hatched, these fish will act as a genetic variation for the Jindabyne system, and future broodstock.
The findings from the coded wire tagging program were as follows;
Hughes Ck- total R/T collected 229 including 6 tagged 2 false detection’s due to fish hooks ect.
Tolbar Ck total R/T collected 102 including 1 tagged
Hatchery collected 366 Rainbow trout from the Thredbo River, with a total of 26 fish tagged and 4 false detection’s due to fish hooks etc. These tagged fish were from 3 year classes.All unwanted 2+ 3+ rainbow trout broodstock (230 individuals) have been released into Lake Jindabyne with an elastomer implant (pink) inserted near the left eye(please see attached photo). Brook Trout and Atlantic Salmon have just started to hatch, with the brown hatchlings running a bit late due to the late trapping season.If anyone would like any further information please don’t hesitate to contact me on the details below.Regards, Mitchel Elkins | Acting Hatchery Manager

I think everyone knows this spot on the Eucumbene river I have pictures of 30 anglers fishing this hole so in other words it holds a lot of Browns and Rainbows depending on the time of year of course at the moment the tell tails signs are there that there has been plenty of fish spawning since the river height has risen and normally a run of Rainbows around mid September although I did see a few fish here I saw a lot more in the smaller streams where the water flow is more consistent water temp is around 6c that’s cold. I think the next big rain will certainly spur the Rainbows on the signs of spring are just starting to show.
Like I said my opinion only based on the observations of the Lake conditions during the year leading up to the spawning run. All the research done on Trout all around the world is done during the spawning run it is the best time to check on the population of the fish and there condition or lack of condition before spawning. All the Browns in Lake Eucumbene are wild fish there is no stocking of Brown Trout so it gives you a very good idea on how they are handling the changing of the climate conditions. The impact on the food source in the Lake and how the fish adapt to these changes, so we all would remember or heard of the huge Mudeye hatches of the 70s,80s,and 90s but that has changed over the last decade or so and the fish had to adapt, yes there are still Mudeye hatches but nothing like the past.
Well to say that was a unique closing season would be an understatement a lot of disappointed anglers who are just finding out that if your fishing skill is not to standard and the fish numbers are down you will struggle the one question that I was being asked continually was what’s happened to the fish short answer is it’s called fishing not catching. But the real answer was a lot harder to find now after everything has settled down and we still haven’t had a flood in the Eucumbene river maybe all the signs that where there leading up to the close of the season are a little easier to read the value of hindsight is a wonderful thing . This is my opinion on what unfolded from a really wet spring that hung on too mid-December and everything being late to a very hot summer in the mountains that also started late and then the late summer that also hung on the too April and the lead up to winter was also very mild but the frosts of late April and May were more like the good old days but no rain of any significance to flood the river and allow the fish to move in that is if they were there to start with. Which brings me to the next thought process as I said my opinion only over the last 8 years except for this season the spawning run has been world class so the weather was one factor this also impacted on the food source for the Trout and another strange occurrence was over the last 5 to 6 years there had been a large population of Pelicans 3 seasons ago I counted 55 and also Cormorants in the hundreds but this season only 1 Pelican and a few Cormorants it would appear that the birds and the fish are well ahead of us when it comes to reading what’s happening around us. I know this may not of answered any questions and that’s fishing always a good spot around the next bend or over the hill. Tackle shop is packed away for the next few months and I have Snowerks Ski & Snowboard Hire up and running for the next 2 months. Enjoy the break I know I wont.
Well this is it the last week of Trout season and by now you would know the fishing this spawning season has been very different from the last 8 years or so I do know that if you’re lucky enough to pick a pool that looks fishy and you put the hours in you will catch most days I have anglers coming and saying how hard it is and then a group will come in and show me a heap of pictures of their catch so the fish are there just not in the numbers of previous years I have been asked what I think is going on and the truth is I don’t think the Browns will run in the large pods of previous years and most maybe still in the lake not ready to spawn at the moment I have a feeling that the best is yet to come .
The rain of last weekend certainly got the Eucumbene river back to its very best with the high water the fish moved in even with all the heavy coloured water and the normal leaf material they navigated their way in but as the season has shown us this is not a normal year as quickly as the river came up it dropped and with the dropping river the big run of fish slowed down to the ones that have to go. The fish are still moving in but nowhere near as many fish the river is still a little higher than it was before the rain but still very hard work for the Browns of any size to move in. As I have said the season appears to be a month behind this year so the best is yet to come .
Still no rain and the river is gin clear with most morning this week being below zero condition have been very tough but if you stick to it the rewards will come a very nice Brown landed by Chilli
