On marten fisher lynx and beaver only.
But quotas are specific to each rtl,but no limit on amount of rtls you can trap,except your physical ability.
I used to run many lines on weekly checks when I was younger,never check the same trapline each day.Take one day a week off to skin.
Each line would be checked once every 7 days since all sets are lethal.
I only trap 3 rtls now because of my age.
I produced a lot more fur when I was younger and held down a full time job at the same time, than i do now that i am retired with more time.
I thought I would be able to trap like a maniac once I took my pension from the railroad unfortunately things dont work that way.
I do keep in the fur game though by trapping, tanning,designing and sewing fur articles the latter being much easier,on the old joints and often more lucrative than trapping full bore.
