Everyone here would prefer to utilize snares but we can't and I personally have not seen what I would consider damage that would I would get docked for- I get downgraded more on rub marks but not from the CR's. During the original study, every animal that was caught underwent a necropsy by a veterinarian to determine injurie scores, not to the fur quality but to the animal. Following that, every animal was put up by a professional fur handler, tanned and then inspected by NAFA. Then numerous ideations took place to improve the scores by adding design modifications to what is now our current CR. The following is some of that detail.
Injury Scores – ISO Standards
We also evaluated injuries using the International Standards
Organization (ISO) Injury Scoring System, another
independent measure. With this cumulative numeric
system a final score of 55 or less is necessary to be
considered acceptable. This scoring system means the
lower the score, the better. The final numeric score of this
study for all coyotes and foxes was 6.8 (Table 2). This
independent evaluation supports and parallels results of
the IAFWA injury score system.
Pelt Studies
In 2001 pelts were skinned, stretched, dried and then
tanned by a commercial tannery to determine affects of
restraints on fur quality. Professional fur graders for
North American Fur Auction, Inc. (NAFA) inspected all
pelts and determined little to no damage to any furbearer.
