Figure 1.— Location of sampling stations in the North-South coastal survey (right) and at Moolack Beach, the grid stations I, II, III, 

 and within Yaquina Bay (left). In Yaquina Bay the numbers 1-4 indicate locations of stations for sampling in 1970-72, the solid dots loca- 

 tions in 1977-79, and the arrows indicate seine stations in 1977. 



5) North-south coastal survey: 1.52 m beam trawl 

 collections were made from 111 km to the north (lat. 

 45°37.5'N) and 111 km to the south (lat. 45°36'N) 

 of Yaquina Bay at 9.3 km intervals (Fig. 1) at depths 

 of 9-18 m in June 1977 and May-October 1978. 



Most samples were preserved in 5% Formalin 6 and 

 seawater. In the laboratory fish were identified, 

 sorted, and standard length (SL) measured to the

nearest millimeter. Nearly all English sole captured 

 in Yaquina Bay were 150 mm SL or less and included 

 0- and I-age fish (Rosenberg 1982). We call these 

 fishes "juveniles" in this paper. 



RESULTS 



Variability of Catches 



The variability of the number of juvenile English 

 sole caught per m 2 in repeated trawls within the 

 same area was low. Coefficients of dispersion (s 2 /x)
