I'm not sure but you could probably find out what chemicals are being trialled by contacting NIWA, Fish & Game Southland or Environment Southland.  I have heard that one of the trials has involved a copper solution - Cu in solution or CuSO4 - perhaps.  I tend to believe that we look at the Didymo problem as a doom & gloom situation.  I know that there are areas in the upper Clutha that were once covered in Didymo (the channel on the true right just upstream of the red bridge at Luggate) that now appear clear.  I recall reading information in the Southland Times about the Mararoa or Waiau where it seemed Didymo was declining.  From a gut feeling, I tend to agree with Militaris, the problem will (perhaps) sort itself out.]]> Mon, 11 Sep 2006 19:49:41 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215895&title=stream-restoration#215895 <![CDATA[Stream restoration : I am personally suspect that in...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215806&title=stream-restoration#215806 Author: ThomasW

I am personally suspect that in the medium to long term that the problem would sort itself out. It is rare for a organisms to completely dominate for a long time in any environment.

I just hope that it occurs within in 10 years, not 100. ]]> Mon, 11 Sep 2006 16:21:25 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215806&title=stream-restoration#215806 <![CDATA[Stream restoration : any details avaiable on what they...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215797&title=stream-restoration#215797 Author: Tobias Alawishous

any details avaiable on what they are trialing Mudfish ?
 
Adds another dimension to the control of access and fishing rights in my opinion. If you can control access then in theory you can control or at least better control the spread of Didymo. I'm not saying I want rivers privatised ala UK but with unrestricted public access it is nigh on impossible to control the spread. A Catch 22 to say the least. Something to think about.

There are Didymo control trials presently underway in Southland.  With luck, our scientists will find a way to control it, eradication I fear, is out of the question.  None of us have any idea of where the Didymo problem will end, if it does.  The hard facts are that rivers in 3/4s of the area of the South Island are possible habitat for Didymo, and around 1/4 of the area of the North Island, particularly central NI.  It's a sobering thought.  Here's hoping our scientists can come up with the goods.]]> Sun, 10 Sep 2006 23:09:39 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215667&title=stream-restoration#215667 <![CDATA[Stream restoration : I suspect that any river or tributaries...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215664&title=stream-restoration#215664 Author: ThomasW

I suspect that any river or tributaries in affected catchments would be contaminated rather quickly. I would prefer to see whole catchments classified as contaminated, and treated according rather then just certain rivers in them. They are all interconnected anyway.

Remote rivers, on the upper sides of lakes might be protected for a while. Would be interesting to see how long it takes for it to spread up the Buller and into Lake Rototit and hence into the travers. The boats and kayaks which operate on the lake would quicken its spread to the head.

I might have to take a trip over to the Buller one day to see what it is like in person. ]]> Sun, 10 Sep 2006 22:57:18 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215664&title=stream-restoration#215664 <![CDATA[Stream restoration : Re.

Re. Didymo, we now have it in the Mataura near Athol, the Eglinton (a trib. of Te Anau), the Matukituki (a trib of Wanaka), as well as the Oreti, Aparima and its trib. the Hamilton Burn, Whitestone, Mararoa, upper & lower Waiau, Upukerora, Fraser River (a trib. of the Clutha), upper & lower Clutha, Von (a trib. of Wakatipu), Hawea R., Ahuriri, Twizel, Ohau, Waitaki, Buller (there's probably a few other waters around the Buller), and Lakes Dunstan, Benmore & Manapouri.  Next season, I am expecting it to be found in the Manuherikia, Lindis, Timaru River (a trib. of L. Hawea), Makarora and the Tekapo R.  I am certain it will end up in the central North Island in time, the Tongariro would be perfect habitat.  First found in the Waiau & Mararoa in Oct. 2004, I saw it in the Hawea the day (28 Sept 2005) Southland F & G Officer Stu Sutherland found it there, small growths about the size of a 5 cent piece.  By the end of December 2005, I estimate at least an 80% coverage of the upper Clutha riverbed.  There is great difficulty fly fishing in it, even with dry flies (during its bloom).  This probably should be on another forum (shift this message if you wish), but I thought you guys should know.  In my opinion, it poses the single greatest threat to NZ's freshwater eco-systems and freshwater recreation.  Be vigilant, keep it out of the central NI for as long as you can.  It's a very sobering sight when you have the pleasure of its company.]]> Sun, 10 Sep 2006 22:26:13 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215657&title=stream-restoration#215657 <![CDATA[Stream restoration : The wild trout site looks the...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=15803&PID=215301&title=stream-restoration#215301 Author: Tobias Alawishous
