5203 |a"Prey incidence was compiled from port liaison officers' notes recorded while collecting length-frequency samples of Pacific cod (Gadus macrocephalus), rock sole (Lepidopsetta bilineata), and petrale sole (Eopsetta jordani in trawl landings originating from three major offshore regions of British Columbia during 1950-80. Principal prey species were sandlance (Ammod tes hexapterus), herring (Clupea harengus pallasi), "shrimp" (assorted Crustacea) and sablefish (Anoplopoma fimbria), the latter only in Pacific cod Stomachs. Sandlance was an important prey species for all three predator species and in all three offshore regions. Incidence periodicity was demonstrated for sandlance (X̄ = 4.2y); herring off the west coast of Vancouver Island (X̄ = 3.9y); and sablefish in Hecate Strait (7-9 y)"--Abstract, page iii.
