Values are means ± SE (n = 3). Values in the same column with different letters a, b, and c are significantly different (). 1IBW, Initial body weight (g). 2SR, Survival rate (%) = 100 × (final fish number/initial fish number). 3FR, Feeding rate (%BW/d) = 100 × intake of feed dry matter/(days × (final body weight + initial body weight)/2). 4FBW, Final body weight (g). 5SGR, Specific growth rate (%/day) = 100 × (ln final body weight−ln initial body weight)/days. 6FE, Feed efficiency (%) = 100 × (weight gain + dead fish weight)/dry weight of feed. 7PER, Protein efficiency ratio = (final body weight−initial body weight)/intake of protein. 8PRE, Protein retention efficiency (%) = 100 × amount of body protein deposition/intake of protein. |
