I landed 4 Fish last season (12lb to 16lb), (lost many more). I went in with a goal of getting 5 to keep, and anything over that would be released.
I have the same goal this year.
if at any point I feel I need more salmon from the freezer, I will go to the canals.
And if I catch anything up over the 20lb mark, I would feel obligated to release because i see these fish as Geneticly superior.
So far down south I have heard of a few smaller(6-9lb) fish being landed around the Otago harbour Basin and Taieri River Mouth. I havent heard anything from the Waitaki or Clutha River Yet.
