Evaluasi Penggunaan Minyak Ikan Dalam Proses Pembesaran Clown Fish Amphiprion percula
Feed enrichment in aquaculture has been known since long time ago which intended to enhance concentrations of important nutrients within natural food in order to promote growth and diseases resilience. In general, the enrichment of natural feed for aquaculture organisms are mainly to increase fatty acid and amino acid groups which essential for metabolism and growth. However, to date, the effective application of feed enrichment in aquaculture is rare to be evaluated for better understanding whether it’s capable to stimulate growth and resilience capacity to diseases. Hence, this study was aimed at evaluating the usage of enriched pellet with fish oil (Scott Emulsion and Curcuma-plus) in enhancing growth of juvenile Clown Fish Amphiprion percula in aquarium for 30 days. ANCOVA test shows that neither pellets enriched with Scott Emulsion nor Curcuma-plus significantly affected the growth rates of Clown Fish. However, further correlation test indicates that the enriched artificial fish feed with Scott Emulsion promoted better growth (r =98) in compare to those that fed with Curcuma-plus (r =0.89) as well as to control (r =0.62) condition. Moreover, Specific Growth Rates (SGR) of Clown Fish also shown better growth fed pellet enriched with Scott Emulsion (33%) particularly in the final 2-weeks than those that fed with Curcuma-plus and none enriched feed. Other findings of this study, the water quality of salinity, pH and dissolved oxygen were also negatively affects to the growth of Clown Fish A. percula. It is advisable that the use of Scott Emulsion in feed enrichment for aquaculture organisms is more profitable than that of Curcuma-plus mainly in stimulating growth of Clown Fish from juvenile to commercial size prior to sale them as ornament fish.
