The in itial weights, and those at one month and the conclusion of the
experiment (two months), were measured and used to calculate the
mean specific growth rate (SGR) (% weight gain day−1) of all
treatments. Condition factor (K) was also calculated, as outlined below where Wi is the weight initial (g), Wf is the final weight (g), L is the
fork length of the fish (mm), and Duration is measured in days.
