A hydroacoustic survey of Pacific hake on the continental shelf off British Columbia from the Canada/U.S. boundary to Queen Charlotte Sound : August 13 to 28, 1991 / by K. Cooke, R. Kieser, M.W. Saunders,... : Fs97-4/2174E-PDF

"A hydroacoustic survey for Pacific hake was conducted off the lower west coast of Vancouver Island and into Queen Charlotte Sound from August 13 to 28, 1991. Total and hake biomass estimates are given for the survey area. Summary information of associated midwater trawl catches is included. Acoustic biomass estimates from research conducted on the influence of environmental factors on hake distribution are reported. Successive passes were made over a 350 km² grid to compare day and night acoustic biomass, observe fish distribution and diel behavior patterns, examine variability in acoustic abundance estimation and obtain information on optimal survey procedures"--Abstract, page iii.
