Table 2.
Growth performance, feed utilization and condition factor of juvenile blunt snout bream fed with the experimental diets.
Mean values and standard error (± SE) are presented for each parameter. Significant differences within the diets are indicated by different letters (P < 0.05).
SGR (specific growth rate) = 100 × (Ln final fish weight − Ln initial fish weight) / the experimental duration in days; FCR (feed conversion ratio) = dry diet fed / wet weight gain; PER (protein efficiency ratio) = wet weight gain / protein intake; FI (feed intake) = dry diet fed / (final fish weight + initial fish weight) / (2 × the experimental duration in days); digestible energy intake = digestible energy in feed × feed intake
