The Effect of Different Colors of Rearing Containers on the Growth and Survival of Glass Catfish (Kryptopterus palembangensis)

 Abstract

The glass catfish (Kryptopterus palembangensis) is an endemic Indonesian fish with high economic value, which has contributed to intensive fishing pressure. A biological approach to domestication is therefore necessary, including evaluation of how rearing-container conditions affect fish performance. This study aims to determine the effect of different colors of rearing containers on the growth and survival rate of glass catfish. The study used an experimental method with a completely randomized design (CRD) consisting of five treatments and three replications, namely P1 (red), P2 (blue), P3 (white), P4 (orange), and P5 (black), and the observed parameters included growth, survival, and glucose levels. The results showed that P5 (black) gave the best results in increasing growth, as indicated by absolute weight (3.25 ± 0.10 g), absolute length (2.80 ± 0.10 cm), SGR (0.64 ± 0.03%), DGR (0.11 ± 0.00 %/day), survival rate (100 ± 0.00%), and normal glucose levels (45.67 ± 2.91 mg/dL), followed successively by P2 (blue), P1 (red), P4 (orange), and P3 (white). During rearing, water quality remained within the optimal range with pH 6.10-6.57, temperature 28.30-30.20°C, DO 4.67-5.17 mg/L, and ammonia 0.13-0.15 mg/L. Overall, the findings demonstrate that black containers are the most suitable option for supporting the growth and survival of glass catfish.
