PENINGKATAN PERTUMBUHAN DAN EFISIENSI PAKAN IKAN GABUS (Channa sriata) MELALUI OPTIMASI KANDUNGAN PROTEIN DALAM PAKAN
Abstract: An experiment was
conducted to investigate the effect of protein levelin diet on feed eficiency
and growth rate of Snakehead (Channa striata). Fivediet with different level of
protein, diet P25(25% protein); P30 (30% protein); P35(35% protein); P40 (40% protein);
and P45 (45% protein) were applied in thisexperiment. Ten fishes with initial
body weight range 0.7 – 1.0 gram were rearedin each aquarium (water volume 10
L). Fishes were fed three time a day, atsatiation. Fish reared for 30 days.The
result showed that growth rate and feedefficiency of fish fed diet 25% protein
level (P25) were0.28 g and 2.46%, diet30% protein (P30) were 0.71 g and 9.86%,
diet 35% (P35%) were 0.84 g and14.18%, diet 40% protein were 1.17 g and 16.97%,
or diet 45% protein (P45)were 1.00 g and 9.58%. Based on BNT test showed that
diet 40% protein levelwas higher growth rate and feed efficiency of fish than
others diet. While survivalrate of fish fed diet 25% protein level was 50%,
diet 30% protein was 46.67%,diet 35% protein was 76.67%, diet 40% protein was
63.33%, or diet 45% proteinwas 100%. Based on analysis of varians, had no
significant different on survivalrate.Water quality of rearing media were
temperature range was 26 – 29oC, pHwas 6.7 – 7.2, dissolved oxygen was 1.46 –
4.16 mg.L-1, and ammonia was 0.014- 0.182 mg.L-1.
