Figure 5— Abundances of young English sole year classes as a function of length. (A) 1969-72, (B) 1977, 



similar for the four year classes sampled between 

 1969 and 1972 in Yaquina Bay (Fig. 5 A). Abundances 

 of recently recruited individuals 20-45 mm in length 

 were similar among the 1970, 1971, and 1972 year 

 classes. The 1969, 1970, and 1971 year classes also 

 increased in numbers/m 2 between 75 and 90 mm 

 before declining to low catches at larger sizes. Abun- 



dances of small fish of the 1969 year class are low 

 because this year class was only sampled in 1970, 

 when most fish were >75 mm. 



Catches/m 2 of the 1977 and 1978 year classes in 

 Yaquina Bay were generally larger than the 1969, 

 1970, 1971, 1972, and 1979 year classes (Fig. 5A, 

 B, C). The 1977 cohort differed from other year
