Table G-4. Regression equation parameters of growth curves (Figures 1-5) for unionid species collected in 



Reach 15 of the Upper Mississippi River in (a) 1994-95 and (b) 1987. Formulas can be used to ^ 

 calculate morphological shell measurements (mm) from unionid age (yrs). All relationships 

 were best described by a third order polynomial regression formula.
