do walleye take a while to adjust to the dark
I don't know but
do you have to take time to adjust to the dark...not if you are outside the whole time.
if you go from a lighted house to the dark you need to adjust, that takes less then a minute
walleye that the 45 minutes as the light levels are changing to dark, I doubt they need much more time once it's dark as they were adjusting all along
just logical thinking , not scientific
