Estimability of Natural Mortality
and Other Population Parameters in a Length-Based Model: Pandalus borealis
in Kachemak Bay, Alaska
Authors: C. Fu and T.J. Quinn |
| The authors compared the robustness of stock assessment
model approaches to several parameters—natural mortality (M),
catchability (q), a survey gear selectivity parameter (L50),
and data imprecision. The results suggest that interannual variations
in M and L50 can be estimated, if the underlying values
have a trend over time. However, parameter q should be fixed at
a chosen value even if it varies over time. Canadian Journal of Fisheries
and Aquatic Sciences 57:2420-2432.
