Correction to the Beverton and Holt Z-estimator for truncated catch length-frequency distributions

A method for estimating the instantaneous mortality rate (Z) is presented which was developed from a truncated equation for average length. The model has zero bias at equilibrium, but has no explicit solution for Z so that its solution requires a numerical method.
