Abstract

In this paper, we set out the prerequisites for the development of killing and
restraining trap systems to capture mammals for research, wildlife management and conservation,
fur trapping, animal control, and any other activity involving the trapping of a mammal in a
mechanical trapping device. We selected them with the main intent of developing new trapping
standards that will improve animal welfare as per our current state of knowledge, and with realistic,
achievable objectives based on state-of-the-art trapping technology. The proposed new standards
should be applicable to all terrestrial and semi-aquatic mammal species. They should be based on
animal testing in semi-natural environments and on traplines, with high trap thresholds of
acceptance, low times to irreversible unconsciousness for killing trap systems, an understanding of
the impacts of trapping on physical form, behaviour and physiological function, adequate trap
checking times and handling of the captured animals, and high capture selectivity. Furthermore,
the implementation of improved trapping standards would include the mandatory publication of
findings for peer-review and public education. We believe that the prerequisites that we lay out for
the development of new mammal trapping standards will address many of the welfare concerns
voiced by the scientific community and the public in the last two decades. It will lead to improved
animal welfare and spur continuous improvement in the efficacy and innovation in trapping
technology.
