THE GROWTH AND FEED EFFICIENCY OF SUBNOSE POMPANO (Trachinotus blochii) PERIODICALLY FASTED

Abstract

The objective of this research was to address the effect of fasting and periodical fasting pattern on feed efficiency and growth rate of Subnose Pompano (Trachinotus blochii). The resarch was conducted at Balai Perikanan Budidaya Laut Sekotong (Sekotong Marine Aquaculture Center), West Lombok, from July to August 2017. This research used experimental method with Completely Randomized Design consisting of 5 treatments for the fishincluding (P1) feeding without fasting, (P2) a day of feeding and a day of fasting, (P3) a day of fasting and 2 days of feeding, (P4) a day of fastingand 3 days of feeding, (P5)a day of fasting and 4 days of feeding. Growth and survival rate data were analyzed by using ANOVA (? =5%) and LSD (? =5%). Whereas, data regarding water quality were analyzed descriptively. The result showed that Subnose Pompano experiencing periodical fasting had decreasing growth rate and feed efficiency. However, analysis on survival rate data did not show a significant difference between the treatments.
