McLeod Posted August 28, 2019 Posted August 28, 2019 Alot quantitative crap without qualitative data. Quote
McLeod Posted August 28, 2019 Posted August 28, 2019 Further to that suggestions were ones being discussed in the 80's ..LOL Quote
fishjunkie Posted August 29, 2019 Posted August 29, 2019 It's a long read. Originally they used 50% mortality for catch & release bull trout for their modelling. It was later reduced to 33%. Unfortunately there isn't much measured data for catch & release on bull trout in Alberta. So what is the real number? No one really knows but 33 percent seems high to me. Obviously if you are a biologist advocating for closing a river you are going to pick (guess) numbers for your model that supports closing a river to fishing. When the Pembina reopens to fishing I'm sure it will be deemed a success by the biologists and used as the "proof" for more river closing. Quote

Its is now full of Brook trout so not sure they can claim it as a success Quote
albertatrout Posted September 10, 2019 Posted September 10, 2019 Yup, Pembina did not need a closure to make more brook trout, it was already loaded.. An incredible amount of real data was ignored before that closure was made essentially just on a pile of assumptions. Hope to hear some changes on that file but not holding my breath. Quote
SilverDoctor Posted September 10, 2019 Posted September 10, 2019 How many of us have caught the same trout numerous times with no seemingly ill effects? Quote
