1Total length (L).
2Fulton’s condition index (CI) = 105W/L3 where W is the weight and L is the total length of the fish.
3Total weight gain (kg) = (final weight -initial weight) .
4Absolute growth rate (g fish-1day-1) = (w2-w1 / t2-t1) increment of weight W2-W1 over a known time.(t) interval.
5Specific growth rate (% day-1) = 100 x (loge final wt.-loge initial wt.)/days.
6Feed conversion ratio = dry feed intake (g)/wet weight gain (g).
7Feed conversion efficiency (%) = wet weight gain (g) x 100/dry feed intake (g).
8Protein efficiency ratio = wet weight gain/protein intake.
Table 3: Influence of feeding frequencies: every day six days week-1 (6 days on - 1 day off), every other day (1 day on - 1 day off) and every two days (2 days on - 1 day off) at noon (12-1 pm) on growth parameters, feed efficiency and condition of two-year-old mulloway (Argyrosomusjaponicus) reared in tanks for 30 days. Data are means (± standard error) of three replicatetanks (20 fish each) for each frequency. Means with different superscripts (a,b) within rows are significantly different (P < 0.05; Tukey test). P is probability value and *is significant.
