MONTHS 



Figure 5.— Mean marginal increment by month for otoliths of Centropristis striata. 

 Number in parentheses represent monthly number of otoliths examined. 



Table 3.— Means (x), standard deviations and sample sizes for observed lengths 

 (mm) and weights (g) by age for Centropristis striata. 



Table 4. — Least square linear and geometric mean functional regression equations of weight (WT) on total 

 length (TL) and standard length (SL), and length-length for Centropristis striata. Weight units are grams and 

 lengths are millimeters. All least squares regressions were significant at o = 0.01. 



Least squares regressions of SL (mm) on otolith 

 radius (OR in ocular units) are 



log 10 SL = 0.668 + 1.056 log 10 OR; 



n = 12,011; r 2 = 0.89. 



The intercept of the SL-OR relationship was used 

 to obtain the mean back-calculated SL's at age which 

 were lower than observed SL's in all cases (Table 

 5). Weighted least square estimates of von Ber- 

 talanffy parameters, asymptotic 95% confidence 



Table 5.— Observed and back-calculated mean standard length 

 in mm and von Bertalanffy standard length at age for Centropristis 

 striata.
