Sea run trout tactics – Craig Vertigan

Sea run trout tactics – Craig Vertigan

During the trout off-season I tend to spend a bit of time chasing bream, to continue getting a fishing fix, and spend time tying flies and dreaming about the trout season to come. It’s a time to spend doing tackle maintenance, stocking up on lures and dreaming up new challenges and goals for the trout season ahead. When the new season comes around I usually spend the first few months targeting sea runners. Sea run trout are simply brown trout that spend much of there lives out to sea and come in to the estuaries for spawning and to feed on whitebait and the other small endemic fishes that spawn in late winter through spring. Mixed in with the silvery sea runners you can also expect to catch resident fish that have the typical dark colours of a normal brown trout as well as atlantic salmon in some of our estuaries that are located near salmon farm pens. Living in Hobart it is quick and easy to do a trip on the Huon or Derwent and is a more comfortable proposition compared to a trip up to the highlands with snow and freezing winds to contend with.

Turbidity in Arthurs Lake

The situation at Arthurs has come up a bit lately and from what we can tell the turbidity in most of the lake as increased very slightly (from 3 to around 5 ntu) due to increased algal growth, I would love to have this sort of turbidity reading for Sorell and Crescent which remain over 50 ntu and have been over 400 during the drought!. The most likely cause is increased nutrient availability following inundation of large areas of previously dry ground. The reports that I have received regarding the condition of fish in Arthurs have varied greatly and I suspect that this is due to a significant proportion of older fish in the lake at the moment, I don't think it has anything to do with the turbidity problem.
Most of this is best guess stuff that would require detailed investigation to get a definitive answer.
