Acoustic Transmitters Impact Rainbow Trout Growth in a Competitive Environment

Table 3: Mean (SE) increases of overall weight, percentage increase from initial to final weight, total length from initial measurements to final measurements, and specific growth rate (SGR)^a for Rainbow Trout held in three separate raceways (A, B, C). Mortality is the total number of individuals that died per raceway. For each variable, values within a row with different letters are significantly different (P < 0.05).

	A	B	C
Weight gain (g)	330 (24) zy	359 (32) z	243 (31) y
Percent weight gain (%)	106 (15) z	124 (16) y	107 (17) z
Length increase (mm)	63 (26) z	69 (21) z	48 (22) y
Percent length increase (%)	62.9 (5.2) zy	69.1 (4.6) y	49.2 (5.2) z
SGR	0.443 (0.019) z	0.470 (0.025) z	0.362 (0.031) y
Mortality	8	9	6

^aSpecific growth rate (SGR) = [(Log final weight - Log initial weight) / time interval] x 100
