ABSTRACT Decoupling emigration from mortality is critical for accurately estimating mortality in recapture surveys. However, open-population models often suffer from their inability to distinguish between these two parameters. A model is presented here that separates emigration from mortality based on movements of a tagged population of 42 hatchery-reared queen conch, Strombus gigas, released into a 20 m x 20 m plot in the nearshore waters of the Florida Keys. The model was constructed in a 4-step process. Recapture sampling of uniquely tagged individuals was used to derive a frequency distribution based on the movements of these individuals over a given time period. A ...
