Results of two boat trawling for juvenile salmonids in Discovery Passage and nearby channels, northern Strait of Georgia / by C.D. Levings and M. Kotyk. : Fs97-4/1730E-PDF

"Chum, pink, coho, chinook, steelhead, and sockeye juvenile were sampled with a two boat trawl in channels leading off the northern Strait of Georgia. Chum dominated the catches and peaked in abundance in late June, as did pinks. It is probable that the majority of the chum were from the Fraser system. Chinook and coho were less abundant and were primarily fish from Quinsam hatchery. Steelhead and sockeye were uncommon. Length frequency data are given for fish subsampled from the trawls. Judging from data obtained in June 1983, most of the chum migrating to sea from the northern Strait of Georgia use Discovery Passage. If stock composition were determined, Discovery Passage could be a useful monitoring location for migrating juvenile salmonids"--Abstract, page iii.
