Effect of Protein Level and Energy-Protein Ratio on the Broodstock Growth Performance of Senggaringan Fish (Mystus Nigriceps)

Abstract

This research was conducted to evaluate the effect of protein level and energy protein ratio on the growth performance broodstock of Senggaringan fish (Mystus nigriceps). Three experimental diets and five replications were used in this experiment. Diet A containing 25% protein with energy-protein ratio 18.0 kcal/g protein (25%;18.0), B containing 30% protein with energy-protein ratio13.9 kcal/g protein (30%;13.9), C containing 35% protein with energy-protein ratio 12.0 kcal/g protein (35%;12.0). Fish was fed on experimental diets two times a day at libitum for 35 days. Based on body weigth biomass of the fish, A treatment has a growth from 43.06g to 44.25g, treatment B growth from 43.31g to 46.36g and C treatment growth from 47.40g to 47.70 g. The result found that diets B produced the highest growth performance.
