Includes bibliographical references (pages 5-6). "Pacific herring in Hecate Strait over winter in two major areas: Browning Entrance on the mainland side of Hecate Strait and the inshore waters of Juan Perez Sound off the south-eastern Queen Charlotte Islands. We conducted an acoustic and fishing survey of these herring aggregations from November 30-December 10, 1992 aboard the research vessel, W.E. RICKER. Total echo integration biomass estimates of midwater herring were 12,500 tonnes in the Browning Entrance area and 21,400 tonnes in the Juan Perez Sound area. Hydroacoustic estimates and model based stock forecasts were similar in the Queen Charlotte Islands District but were significantly different in the Browning Entrance/Prince Rupert District. A compilation of 1985-1993 model based stock forecasts and estimates are compared with acoustic survey estimates"--Abstract, page iii. Includes abstracts in English and French.
