Abstract

This research was conducted for 21 days in October 2019 at the Laboratory of Fish Seed Center (BBI) Faculty of Agriculture, Riau Islamic University, Pekanbaru. This study aims to determine the effect and optimal dose of cherry leaf extract solution on the incubation time, hatchability and survival of larvae of catfish (Clarias gariepinus). The method used is an experimental method using a Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely: (P1) 2.0 gr / l, (P2) 2.5 gr / l, (P3) 3.0 gr / l , (P4) 3.5 gr / l and (P5) 4.0 gr / l. The test eggs used came from artificial spawning at the Fish Seed Center (BBI), Riau Islamic University. The container used is a jar with a capacity of 10 liters of 15 pieces. The results obtained, for the best adhesion is found in (P5) 4.0 gr / l of 96.89%. For the incubation time and hatchability of the best treatment at (P3) 3.0 gr / l, the incubation time is 17 hours 27 minutes, for hatchability of 83.33%. Furthermore, the best treatment life in (P2) 2.5 gr / l was 42.08%. The results of measurements of water quality parameters in this study, have temperatures ranging between 290C-340C, pH 66.5, ammonia between 0.28-0.97 and DO ranging between 3.14-3.81.
