  1. TL – Total length; InW – Iinitial weight; FW – Final weight; WG – Weight gain; FCR – Feed conversion ratio; SGRw – Specific growth ratio (weight); The table shows values of mean ± SD of three experimental repetitions; Values within the same row with different superscript differ significantly (p < 0.05); Experimental diets are explained in the foregoing text.
