'Rats, when they are worth something, Oct 15 w freeze up early Nov. so got about 2 1/2 wks to get them. Mk - when they worth something Nov. 1. Long hair opens Nov 1 but try to hold off til Nov 15 for better chance get hvy vs semi grade. Bvr Oct 15 but try hold off to Nov 1 to get better chance hvy vs semi grade. Fine line between semi and hvy grade and freeze up and more work trapping under ice w every yr a bit different for snow and freeze up. No RTL's around here too so some places gotta get gear out early due to competition. We had a big 12 year argument w govt from '97 - 2009 to get long hair moved from Oct 15 to Nov 1. Too many idiots wanted to trap crap long hair fur cause a bit easier to trap in Oct and govt ppl just so ignorant but we won in the end. Was a big problem w no RTL's and lots of competition. I lead the charge on that one and takes a toll on ur head fighting stupid cause stupid can not be fixed.
With RTL its not really an issue when season opens.
Many years ago they moved fox to sept 15 start in the north from Oct 25-Cause guys wanted to use the dirthole set before freeze up.Very flat skins at that time but good colour.Good colour at that time trumped hvy skins.That market did not last however,but they left the season as is.(in southern Ontario fox has always been open year round because they are a pest).
No one I know takes fox before 25 oct when other land fur opens,and most wait until November to trap land fur,except maybe marten which prime up pretty early here.
With RTL harvesting early fur,overharvestin or underharvesting only hurts yourself and your lines.
