520	|aThe purpose of this paper is 1) to make available to assessment scientists a review of the methods used in six acoustic surveys that were completed between 1981 to 1998 to estimate Pacific hake (Merluccius productus) abundance in the Strait of Georgia and 2) to provide a time series of hake biomass standardised to a single target strength value. This includes a description of the evolution of the acoustic system, data collection, analysis, presentation techniques and sources of uncertainty unique to each survey. A method for calculating biomass based on target strength length relation is presented and biomass estimates from all surveys are given. Calibration, target strength and survey data are statistically examined to obtain a representative confidence interval that can be used as a guide for all surveys.
