Hydroacoustic herring survey results and trawl catches from Hecate Strait, July 14-27, 1987, W.E. Ricker cruise WER87F / by B. McCarter, R. Kieser and D.E. Hay. : Fs97-4/1996E-PDF

"Coastal waters within the 50-200 m bottom contour of Hecate Strait were surveyed to determine Pacific herring abundance estimates and distribution patterns. Total midwater biomass estimates were 3,300 tonnes at Two Peaks and Butterworth edge, 1,140 tonnes at Browning Entrance, 1,090 tonnes SW of Bonilla Island, 570 tonnes at the Horseshoe grounds and 1,320 tonnes off Ramsay Island. Midwater species assemblages of pollock, dogfish and herring precluded separate estimates of herring biomass. Species composition of five midwater trawl and 66 bongo net catches, stomach contents and size and age distribution of herring were also examined. Oceanographic data were collected at nine hydrographic and plankton stations"--Abstract, page iii.
