Pengaruh Penambahan Papain Dalam Pakan Komersil Dengan Dosis Berbeda Terhadap Pertumbuhan Ikan Nilem (Osteochilus Hasselti) Pada Sistem Resirkulasi
The aim of the study was to determine the best of papain doses best of
commercial fish meal to increase the growth of nilem fish seeds (Osteochilus
hasselti).in recirculation systems. Culture vessel in the form of aquarium of 60 x
40 x 40 centimeters of 15 aquarium with stocking density of 11 fish/m3. This
research was using experimental method by completely random design (RAL) one
factor with five treatments and three replications The treatment applied was the
feeding of the enzyme containing papain with different dosages: P0= without the
addition of the papain enzyme, P1= the addition of the enzyme papain 1,25%/kg
of feed, P2=the addition of the enzyme papain 2,25%/kg of feed, P3= the addition
of the enzyme papain 3,25%/kg of feed and P4= the addition of the enzyme papain
4,25%/kg of feed. The results showed that the addition of enzyme papain in feed,
showed highly significant effect (P0.05) to survival
rate. The best growth rates was found in treatment P1 with total weight: 5.75±0.02
gram, total length: 4.06±0.05 cm, specific growth rate: 4.32±0.02% per day, feed
conversion ratio: 1.23±0.01 and survival rate: 100±0.00%.
