Abstract
We describe a maximum‐likelihood procedure for obtaining simultaneous estimates of growth and total‐mortality rates from size‐frequency distributions. The method is applied to size data from simulations and from two populations of northern abalone Haliotis kamtschatkana in British Columbia. Total‐mortality‐rate estimates varied with the assumed number of age classes and other model variables, but this variation was satisfyingly small.
