Fig. 148 — Stenobrachius leucopsarus, male, 77.0 mm. 



Size: To about 90 mm. 



Least depth of capture: Rarely dipnetted, but commonly taken above 30 m at night. 



Distribution: S. leucopsarus is confined to the North Pacific cold water areas. It occurs 

 from off Baja California, Mexico (about 29° N, 115° W) northward into Gulf of Alaska and 

 Bering Sea and west to Kamchatka and Kurile Islands (Fig. 149). Capture data from Aron, 

 (1960, Fig. 149, dotted lines) indicate that the species is abundant in northern waters; the solid 

 line enclosing near-shore water off southern California, indicates an area in which hundreds of 

 specimens have been taken. Paucity of capture localities in northwestern Pacific may reflect 

 minimal collecting effort. 



Fig. 149 — Capture localities for Stenobrachius n. nannochir (large solid circlesi and S. leucopsarus. For this latter 

 species, the heavy curved line off southern California and northern Baja California, Mexico, encloses an area in which 

 many collections (hundreds of specimens) were made. The thin, straight lines indicate the cruise tracks of expeditions 

 reported by Aron (1960), each dot representing at least one capture of this species. The open circles indicate additional 

 captures of S. leucopsarus.
