Abstract

We compared efficiency and selectivity of 2 cable restraints with a 10.8-cm- (larger) or 8.9-cm- (smaller) diameter minimum loop stop to live-capture coyotes (Canis latrans) in Michigan, USA. Cable restraints were set for 3,166 (larger) and 1,175 (smaller) trap-nights, respectively, during March 2008 and January–March 2009. Capture efficiency was 64% (n = 22 coyotes) and 100% (n = 11 coyotes) for cable restraints with larger and smaller diameter minimum loop stops, respectively. Coyotes captured in cable restraints with larger or smaller minimum loop stops were similar in size. Selectivity of cable restraints with larger and smaller minimum loop stops was 100% and 79%, respectively; nontarget species captured included white-tailed deer (Odocoileus virginianus) and northern raccoon (Procyon lotor). Based on our findings, we recommend the smaller minimum loop stop diameter for capture of coyotes. We also recommend further testing of cable restraints and set placement for coyotes to improve capture efficacy. © 2011 The Wildlife Society.
