Trapping is a wildlife management tool that can be used to control predators
on waterfowl breeding grounds. However, a growing number of people disapprove
of such an activity because they believe that actual trapping devices, particularly
the steel leghold trap, are "cruel and inhumane." On the other hand, recent
research programs produced "humane" traps that either quickly render animals
unconscious and insensitive to pain or live-capture them with minimal trauma.
The rotating- jaw C120 Magnum trap is an example of a "humane" killing trap
that can render marten (Martes americana) and mink (Mustela vison)
irreversibly unconscious within 3 minutes. This capture-efficient trap is a
major improvement over the traditional Conibear 120 trap and is now manufactured.
Other "humane" killing systems were also developed for marten and mink, and
for fisher (Martes pennanti) and arctic fox (Alopex lagopus).
However, for some species, killing traps appear to have limited application.
Research work carried out at the Alberta Research Council recently showed that
the foothold EGG trap was a "humane" device that could hold raccoon (Procyon
lotor) for long periods of time without any serious injury. Other studies
showed that padded leghold traps could substantially reduce limb injuries to
canids and felids. With the development of "humane" killing and live-holding
traps, trigger systems and trap sets were also improved to make trapping more
selective. It is essential for the future of trapping that these "humane" traps
be, immediately incorporated into wildlife management programs. Trap research
programs must be maintained to develop more "humane," alternatives and rigorous
trapping standards must be adopted to ensure that animals will be captured in
the best possible manner.
