Abstract

This study aims to determine the best feeding rate (FR) in increasing feed efficiency and growth of Chopped grouper and to determine the efficiency and growth of Chopped grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus). This research was conducted in February-March 2020 for 42 days at the Household Scale Hatchery of the Marin Agri Sejahtera Cooperative, Tanjungpinang City, Riau Islands. The method used was experimental with a completely randomized design (CRD) with 4 treatments and 3 replications where K treatment (15% trash feed), A treatment (10% trash feed), B treatment (20% trash feed), treatment C (feeding 25% trash feed). The results of the study, through statistical analysis, showed that the papain enzyme dose was able to have a very significant effect.

Abstract

This research aims to determine the effect of appropriate feeding time for the growth of Chopped Grouper Fish (Epinephelus fuscoguttatus x Epinephelus lanceolatus). This research was conducted from March to April 2020 for 42 days at Madong village, silver pompano culture group, Tanjungpinang City, Riau Islands Province. The methodology used in this research was experimental with a completely randomized design (CRD) with 3 treatments and 4 replications, which the T1: fed daily  T2: 1 day given food 1 day of fasting. T3: 2 days given food, 1 day of fasting. Analysis of the data using One-Way ANOVA showed that the best absolute weight growth was found in T1 treatment of (29.13 ± 1.07 g), daily growth (SGR) (0.69 ± 0.03 cm). The results obtained indicate that T1 treatment is the best treatment for growth
