Figure 5. — Standard length-dry weight relationship of larval 

 winter flounder. Points represent means for length and weight of 

 samples of 10-25 larvae. 



In spite of these differences, a visual examination 

 of the length-weight regression equation 

 coefficients and associated parameters for all 

 species reveals no obvious correlations with the 

 differences (Table 1). It would not be prudent to 

 statistically test for differences or associations be- 

 tween the species because data for haddock and 

 winter flounder were averaged. Ricker ( 1973) cau- 

 tions that averaging changes the variances as- 

 sociated with the variables, particularly the inde- 

 pendent variable, so that a comparison between
