Kinerja Pertumbuhan Juvenil Ikan Lele Dumbo (Clarias Sp.) Yang Diberi Pakan Dengan Kandungan Kromium Berbeda

Abstract

This experiment was conducted to determine the effect of different dietary chromium level on the growth performance of catfish (Clarias sp.) juvenile. Five experimental diets contain different chromium level, namely diet A (as a control diet) 0.01; B 1.30; C 2.60; D 3.90 and E 5.20 mg/kg diet were used in this experiment. Fish with body weight of 5.57 ± 0.01 g/ind, fed on the experimental diet, twice a day, at satiation. Feeding trial was conducted for 60 days. Based on the evaluation of protein level of the whole body, protein and lipid retention, daily growth rate and feed efficiency, it was concluded that the optimum dietary chromium level for catfish juvenile was 2.60 mg/kg diet.
