Fig. 2 Mean percentage of fat for Gambusia a f finis collected from 

 thermally affected areas (PCI, PC2, and PCS), open bars (D), and 

 unaffected areas (PP and RP), striped bars (D). (a) Samples from 

 February, June, and October 1970 combined within stations; means 

 for PCI, PC2, PCS, and RP were significantly higher than the mean 

 for PP (a = 0.05). (b) Mean values based on pooled samples from 

 thermally affected and unaffected areas for February, June, and 

 October; means from the thermally affected areas were significantly 

 higher than those from unaffected areas (a = 0.05) in February. 



male and female mosquitofish at PCI and PC2 were usually larger in 

 February and December when periods of low temperatures occurred 

 at these stations. On the average, male and female mosquitofish from 

 the unaffected areas were larger in the summer and fall. 



Mean percentage of body fat of fish from heated areas (PCI, 

 PC2, and PCS) was significantly higher {a = 0.05) than that of fish 

 from unaffected station PP, whereas fish at RP had body fat reserves 

 similar to those of fish from affected stations (Fig. 2a). Male and 

 juvenile mosquitofish from thermally affected areas had a signifi- 

 cantly higher (ce = 0.05) percentage of fat than those from unaffected
