Abstract

The momentum and clamping force values of a standard Conibear 120 rotating jaw animal trap and various modifications were determined using accelerometers and a load cell. These values were then compared against each other and against previous biological studies to determine which have the potential to quickly kill select species of animals.

It was found that by increasing the strength of the springs, and by adding clamping bars to the traps, it was possible to significantly increase both the momentum and clamping force of the standard Conibear 120 trap.

The Conibear 120 does not meet the requisites of the Canadian General Standards Board. More work should be done on traps, such as the C120 Mark IV, which do meet these requirements.
