However, <br />growth, measured as individual fish weight and total biomass, <br />did vary. The low treatment had significantly (p-.1) smaller <br />fish and lower total biomass than the high treatment and the <br />medium treatment. Pairwise comparison of medium and high <br />treatments showed no difference. <br />+ ? 't SLR (avi -cl <br />
