Use of Catch-Effort to Estimate Population Size
Lancia RA, Bishir JW, Conner MC, Rosenberry CS. 1996. Use of Catch-Effort to Estimate Population Size. Wildlife Society Bulletin. 24(4):731-737
ABSTRACT: demonstrate practical field application of catch-per-unit-effort (CPUE) models, based on a new conceptual framework for CPUE developed by Bishir and Lancia (1996), to estimate (1) the antlered buck population of white-tailed deer (Odocoileus virginianus) on Chesapeake Farms (formerly Remington Farms), Maryland, from harvest data collected by deer hunters and (2) the high-elevation population of wild pigs (Sus scrofa) in Great Smoky Mountains National Park (GSMNP) from pig removals by Park employees. An advantage of CPUE estimates is that the required data can be collected by hunters. Compared to the reconstructed buck population, CPUE estimates were negatively biased but correctly revealed major increasing or decreasing trends; similar validation data were not available for the pig population. In cases of sustained-yield harvesting, CPUE estimates are probably sufficiently accurate because underestimates would lead to conservative management decisions.
