Reproductive Status of 



Dover Sole, Microstomas pacificus, off 



Northern Oregon 



Dover sole, Microstomus pacificus, range lati- 

 tudinally from northern Baja California to the 

 Bering Sea (Hart 1973) but are commercially 

 abundant only from central California to British 

 Columbia. They inhabit a wide depth range, 

 from shallow, inshore waters (juveniles) to at 

 least 1,000 m. Ma.ximum recorded size is 71 cm 

 total length (Hart 1973). On the basis of bio- 

 mass, Dover sole is the most abundant species 

 of flatfish landed commercially off Oregon 

 (Demory et al.') and dominates the Columbia 

 Slope Assemblage (located at depths >220 m) 

 described by Gabriel and Tyler (1980). Landing 

 and effort statistics for this species in the Inter- 

 national North Pacific Fisheries Commission 

 (INPFC) Columbia Area (lat. 43°00'^7°30'N) 

 were relatively stable for the 20 years prior to 

 1977, but have since almost tripled (Demory 

 et al^). 



From data extending back to 1951, Demory et 

 al. (fn. 2) suggested a dechne in age-specific 

 length for this species during the last several 

 years (mean length at age 10 years was about
