PERTUMBUHAN DAN SINTASAN BENIH LOBSTER AIR TAWAR (Cherax quadricarinatus) YANG DIBERI PAKAN SILASE LIMBAH VISERAL IKAN

Abstract

This study aims to determine the effect the feed with a basic material visceral fish waste silage and percentage visceral fish waste silage the best on the growth and survival of freshwater crayfis. The experimental design used was a completely randomized design (CRD) with five treatments and three replications. The treatments are T0 = commercial pellets 100% (kontrol), T1= silage 45% + bran 54%, T2 = silage 55% + bran 44%, T3 = silage 65% + bran 34%, and T4 = silage 75% + bran 24%. The parameters observed in this study is survival, specific growth rate, feed efficiency and water quality. The results of the study showed that The feed with a basic material Visceral fish waste silage no real effect on the growth and survival of freshwater crayfish. Based on the water quality data during the study obtained the temperature range between 28 – 30 oC, pH with value 7 and CO2 ranged between 0.18-0.38.
