During the 1974-75 trapping season an evaluation of the No.2 Victor leg-hold trap and the 220 Conibear trap was conducted in nine study areas consisting of fresh and brackish marsh along the Louisiana coast. Twenty-three trappers produced 10,671 trap nights of evaluation with the No.2 Victor and 7,567 trap nights of evaluation with the 220 Conibear. The No.2 Victor caught significantly more (p<05) nutria (Myocastor coypus) in both fresh and brackish marsh study areas. There was no statistical difference (p>.05) in the number ofmuskrat (Ondatra zibethicus rivalicius) taken with the two traps. The No.2 Victor caught significantly more (p<05) non-target animals (birds) than did the No.2 Victor. The 220 Conibear did not kill trapped nutria consistently, with 9.7 percent of the adults and 10. 7 percent of the immature alive in the trap.
