Effect of Stocking Density on Growth, Feed Efficiency, and Survival in Peruvian Grunt Anisotremus scapularis (Tschudi, 1846): From Fingerlings to Juvenile

This study aimed to identify the effect of stocking density on growth, feed efficiency, and survival during transition from Peruvian grunts (Anisotremus scapularis) fingerlings juveniles. Fingerlings were reared in triplicate for 63 days until reaching juvenile stage, at 1000 fingerling·m−3 (low-density LSD, 0.79 kg·m−3), 2000 fingerlings·m−3 (medium-density MSD, 1.58 3000 (high-density HSD, 2.37 production performance parameters evaluated. At end experiment, results showed a negative correlation between individual specific growth rate HSD. The final biomass per treatment was 3.53 ± 0.26, 6.79 0.08, 7.70 0.46 kg·m−3 respectively, harvest weight gain significantly lower there no significant difference (99%) among all treatments. Furthermore, average food each protein efficiency ratio while feeding higher In summary, our indicated that initial values above 1.42 did not improve rearing process.
