Hooking Mortality exists, obviously, but it does not have an impact on fish populations. There is a reason the DNR does not use it anywhere besides Mille Lacs and it’s boondoggle of “co”-management.
How does hooking mortality doesn’t impact fish populations? If we reduce hooking mortality more fish survive, isn’t it like reducing limits? Help me understand.
Hooking mortality is too variable (season, temperature, depth caught, species etc.) that it does not have a measurable impact on fish populations. Which is why the DNR doesn’t use it, also some of the DNR studies on Hooking Mortality/barotrauma have been demonstrably false (see Aaron Weibe’s Barotrauma videos) and are being reworked as we speak. Yes, hooking mortality COULD impact fish populations, but at this point in time it is far too nuanced to be scientifically valid.
The more sound hooking mortality studies (Talmage/Staples on Rainy, Hoxmeier/Meerbeck on P4 and Brueswitz/Reeves on ML), still have the selection bias of the barotrauma studies (holding fish in a hoop net for days), no baseline (how many fish would die if held in a hoop net for 3-5 days without being caught?), while still showing basically no hooking mortality except for the warmest part of the year AND caught out of deep water. If you want to PM me your email, I will forward you the studies and write up I did on this and sent to MN Fish and many other places to try and get some pushback to the DNR for using it as a management tool on ML.
