FIGURE 3. — Monthly mean gonadosomatic indices, ranges, and 95' , confidence limits about means for female Larimus fasciatus, 



spawned groups pooled, October 1979-April 1981. 



TABLE 4. — Summary of iterative process used to calculate final hatching dates and set time scales for 

 growth calculations. Equations describe regressions of observed mean total length (TL) on age in days 

 Initial age values and growth equations were scaled to a 1 October hatching date. Final fitted regressions 

 are in Figure 7.
