Table 2.-Mean (SO) standard length (mm) of razorback sucker larvae at 7-d intervals after exposure for 10 s to one of six
electric fields at 36 h posthatching. Controls were handled the same as treatments but without exposure to electric current.
N = 60 for each treatment and control (three replicates with 20 larvae each). An asterisk (*) denotes treatment means that are
significantly different (P ~ O.OS) than the control mean at each 7-d interval.
