Specific growth rate was determined as: SGR (% animal day _1) = [(LnPh2 _ LnPh1/t)] * 100, where Ph2 Ph1 are final and initial fish wet weight, Ln is the natural logarithm and t is the number of days in the experimental period, and daily gain as: DGW (g animal _1 day_1) = (Ph2 _ Ph1)/t, where Ph2 Ph1 are fish final and initial wet weight and t is the number of days in the experimental period (Mart_ınez, Gallardo, Pech, Navarro, S_anchez, Caamal-Monsreal & Rosas 2014).
