Abst ract:

Stock assessment efforts for the southern New England (SNE) Jonah crab fishery have been impeded by limited life-history and monitorin g data for the species in SNE. Consequently\, selection of optimal managem ent strategies is controversial\, which is particularly concerning given r ecent declines in commercial landings. The present study focuses on using Jonah crab population simulation models to assess and compare two currentl y available monitoring data streams and two proposed assessment methods— an empirical index-based approach and a model-based catch-survey analysis approach. Monitoring data collection and application of assessment methods were compared by simulating these processes on a virtual population\, acc ounting for observation error in data collection\, to see how well the dat a and assessment methods capture “real” dynamics produced by the virtu al population. The model-based method performed slightly better when using data with a greater signal-to-noise ratio\, while the empirical method wa s generally preferred with greater levels of index observation error. This simulation-based approach allows for evaluation of management procedures in a data-limited fishery for which the status of the stock is not well un derstood and is intended to assist scientists and managers in evaluating m onitoring and assessment programs for SNE Jonah crab moving forward.
