Abstract
  • The purpose of this paper is to describe and to compare the food of five flatfish species that actually cooccurred at one specific time and place on the central Oregon continental shelf: English sole, Parophrys vetulus Girard; rex sole, Glyptocephalus zachirus Lockington; rock sole, Lepidopsetta bilineata (Ayres); petrale sole, Eopsetta jordani (Lockington); and Pacific sanddab, Citharichthys sordidus (Girard). These demersal fishes are common along the west coast of North America, their ranges overlapping between southern California and the Gulf of Alaska (Hart 1973). Parophrys vetulus, C. sordidus, and L. bilineata occur mainly on the inner continental shelf. Eopsettajordani is fished commercially on its feeding grounds (73-128 m), and in deep water (311-457 m) where spawning occurs (Forrester 1969). Glyptocephaliis zachirus has a broad bathymetric rangeit is common off Oregon and Washington from 90 to 550 m (Alverson et al. 1964). Off Oregon it was the second most numerous member of a species association ranging from 119 to 199 m, on an average sediment type of 69% sand, 19% silt, and 12% clay (Day and Pearcy 1968). In that same study, C. sordidus and P. vetulus composed 80.3% of a species association of fishes in shallower water (42-73 m) on a sandy bottom. According to Alverson (1960), L. bilineata is common on sandy or gravel bottom. The five fiatfish species attain maximum sizes ranging from 410 mm for C. sordidus to 700 mm for E. jordani (Hart 1973).
