Abstract
Analyses of the tag-recapture data available for the PEI toothfish resource are undertaken to evaluate a vessel effect and an area effect on tag recovery rates as well as to determine a possible difference in tagging “success” between the two vessels operating in the PEI region. Parameter estimates have poor precision because of the scarcity of data, especially when disaggregated by vessel and area. The only statistically significant difference is an area effect on tag recovery rates, with the Centre areas having the highest recovery rates and the West areas the lowest.
