Mean growth increments I of each year class from age 

 (6 months old) to ages 1-5 (/ _,) showed significantly nega- 

 tive correlations (Table 2). Correlations between the two 

 variables tended to increase with age: -0.69 for /,, _,, -0.71 

 for I„_.,, -0.80 for /„_.,, and -0.77 for I ^. 



The relative FL at age for any given year class was 

 maintained throughout the life span. A correlation be- 

 tween the mean FL at age and age 1 within each year 

 class (1970 to 1996 year class) was positive and statisti- 

 cally significant (P<0.05, Fig. 4). Similarly, the positive cor- 

 relations between the mean FL at age and age 3 ( 1970 

 to 1994 year class, P<0.01, Fig. 4), and age and age 4 

 (1970 to 1993 year class. P<0.05, Fig. 4) were significant 

 (P<0.05. Fig. 4). 



Correlation between FL and population density 



Population densities represented by stock in number at age 

 and total biomass were negatively correlated to FL at age. 

 Negative correlations between the logarithm of abundance 

 of age (ln/V ) and FL at ages were relatively high in age 

 to 3 (-0.69 to -0.83, Table 3) and low in age 4 and 5 (-0.63 

 and -0.64, Table 3). Correlations were statistically signifi- 

 cant for ages 0, 2, and 3 (Table 3). Negative correlations 

 between the logarithm of total biomass and FL at ages 

 were relatively high at ages to 2 (-0.73 to -0.75) and 

 moderate for age 3 to 5 (-0.50 to -0.52, Table 4). However, 

 the relationships were not statistically significant for all 

 ages (Table 4).
