Pengaruh Pemberian Enzim Papain pada Pakan terhadap Kelangsungan Hidup dan Laju Pertumbuhan Benih Ikan Lele Dumbo (Clarias Gariepinus)

Abstract

Dumbo catfish farming is intensively to covering the environment, water quality and feeding. Feeding using the appropriate dose enzyme papain can determine the rate of growth and survival rate of dumbo catfish. The research aims to know for giving the enzyme papain to the growth and survival rate of catfish is well and to knowing the amount of enzyme papain which is effective to the growth and survival rate of catfish. This research was conducted from December 2015 - January 2016 in the Laboratory of Aquaculture, Water Resource Management, Faculty of Agriculture, University of North Sumatra. The results showed that the enzyme papain can accelerate length and weight growth of catfish and increaseing the survival rate of catfish . The enzyme papain also significantly affect to length and weight growth of catfish but no real effect on the survival of catfish. The amount of the enzyme papain which is effective for length and weight growth of catfish as much as 2.5% of the enzyme.
