*Values are means of triplicate groups ± S.E.M. Within a row, means with different letters are significantly different (P < 0.05); means with the same letters are not significantly different (P > 0.05). Absence of letters indicates no significant difference between treatments.
Average initial body weight; means ± S.E.M., 25.05 ± 0.1 g.
1Fn wt: final weight (g), 2WG: percent weight gain (%), 3SGR: specific growth rate (% day−1), 4FI: feed intake (g dry diet fish−1 56 days−1), 5FER: feed efficiency ratio, 6PER: protein efficiency ratio, 7PG: protein gain (g kg body weight gain−1), 8PR: protein retention (% of intake), and 9Sur: survival (%).
