Effects of Mangosteen Peel Crude Extract on Growth Performance of Walking Catfish (Clarias macrocephalus) in cement pond

Abstract

Abstract

              The effect of mangosteen peel crude extract on growth performance of walking catfish (Clarias macrocephalus) in cement ponds was studied using a Completely Randomized Design (CRD). The experiment consisted of 4 treatments, each with 3 replicates by using instant feed pellets with protein level 42%. Treatment 1 (T1) included 200 grams of instant feed mixed with 25% crude mangosteen peel extract. Treatment 2 (T2) included 200 grams of instant feed mixed with 50% crude mangosteen peel extract. Treatment 3 (T3) included 200 grams instant feed mixed with 100% crude mangosteen peel extract, and Treatment 4 (T4) served as the control group, containing only 200 grams of pellet feed without any extract. Initial weight 6.76±0.45 grams and length 12.54±1.39 centimeters. Weight and length were measured randomly at 30, 60, and 90 days of the experiment. The results showed that T1 had the highest average weight gain, length gain, survival rate, feed conversion ratio (FCR), daily growth rate (DGR) and specific growth rate (SGR) after 90 days of rearing to analyze the Statistical variance was found that the average weight gain and FCR were significantly different (p<0.01). However, the average length gain, survival rate, daily growth rate, and specific growth rate showed no significant differences (p>0.05). Therefore, this study demonstrates that the supplementation of herbal extracts, particularly from mangosteen peel, has a positive effect on the growth performance of walking catfish.
