An echo sounding program has been conducted since 1967 to provide managers with an early indication of the stock abundance and to assist in the in-season management of the commercial gillnet fishery. This report details the methods used to interpret the Rivers Inlet echo sounding data over the period 1967-1988. An historical record of the sounding equipment used and the estimated daily sockeye abundances is presented in accompanying appendices"--Abstract, page iii. Includes abstracts in English and French.
