Eight-day-old striped bass Morone saxatilis (6.17-6.22 mm, total length) were fed twice daily at three feeding rates to produce three growth rates. Fish were sampled once per week for 4 weeks to determine total length and otolith radius. Feed ration treatments resulted in discrete size-classes of striped bass after 4 weeks with a 27% difference in mean length between the low and high feed ration treatments. No significant differences in slope or intercept for the regression of fish length on otolith radius were observed among treatments, suggesting that slow growth alone may not be sufficient to result in decoupling of the otolith size-fish size relationship in striped bass.
