Meningkatkan Pertumbuhan Benih Ikan Gurami (Osphronemus gouramy) Melalui Metode Pemotongan Sirip Ekor

Abstract

Gurami (Osphronemus goramy) is an economically important freshwater fish species that experiences relatively slow growth compared to the other freshwater fish species. Therefore, alternatives in gouramy culture to increased growth continue to be made. One of them was through the tail fin cutting method, which was expected to accelerate the growth rate, so that good growth will be obtained. The purposed of this research was to analyze the effect of cutting method the tail fin to the growth of Gurami (Osphronemus goramy) fingerling. This research was conducted in the Experimental Pond Units, Faculty of Fisheries and Marine Science,Mulawarman University. Design of this research was used a Completely Randomized Design (CRD) with three treatments and four replications. The treatment consists of the control (no cuts), cutting the 25% tail fin and cutting 50% tail fin. Data was analyzed with Analysis of Variance (ANOVA) and confidence limit 95%. Based on Analysis of Variance showed that the results of this research indicated that among treatment cut off the tail fin to control were significantly effect on the growth of the weight and length, specific growth rate and daily growth rate. The growth of 50% cutting of fin tail was the best than the others.
