Table 2: Mean (SE) specific growth rate (SGR)a for Rainbow Trout during three time intervals over 90 days after undergoing one of three treatments: anesthesia (handled, N= 26), anesthesia and sham surgery (sham, N = 24), and anesthesia and implantation of an inert acoustic transmitter (tagged, N = 18). For each variable, values within a row with different letters are significantly different (P < 0.05).
