<p> A set of scales was created, the "Modified Conibear Scales" which can be used as a basis of comparison to rate the performance of other traps in the areas of impact energy, closing time and clamping force. Further, a detailed set of secondary non quantitative characteristics was presented.</p> <p> Using the above information, several promising traps were rated in order to assess these scales, give some immediate results and indicate promising traps or trap features. Further work in the field was facilitated by providing a detailed experimental procedure, complete lists of data and a calibrated trap for animal research.</p> / Thesis / Master of Engineering (MEngr)

<p> Optimization criteria for trap design were established and a qualitative optimization program on the design of two of the most promising series of traps was carried out. </p> <p> An evaluation of several existing traps was carried out using Johnston's technique. Two traps were calibrated and an impact testing device was designed and built for future research work to be conducted at Guelph University. </p> / Thesis / Master of Engineering (MEngr)
