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.

Effects of Different Natural Feed Types on Domestication, Survival Rate, and Growth of Glass Catfish (Kryptopterus palembangensis)
ABSTRACT
Intensive, uncontrolled fishing has primarily reduced glass catfish (Kryptopterus palembangensis) populations in Indonesian waters, especially in Sumatra, leading to a steady decline in natural populations through continuous overexploitation. The present study aimed to evaluate the effects of different natural feeds on the growth performance and survival of glass catfish during the domestication phase (process of adapting wild fish to aquaculture conditions using appropriate natural feed types). A total of 150 glass catfish, with an average initial length of 14.62 ± 0.53 cm and an average initial weight of 15.58 ± 0.73 g, were subjected to the present study, using a completely randomized design with five treatment groups and three replications. Each experimental unit contained 10 fish, resulting in 30 fish per treatment. The treatment groups consisted of different natural feed types, namely small live fish (P1), shrimp (P2), earthworms (P3), maggots (P4), and Tubifex sp. (P5). Growth performance, survival rate, and digestive enzyme activity of glass catfish were observed after 30 days of rearing. The present results indicated that Group P2 significantly improved the growth performance of glass catfish, including absolute weight (3.61 ± 0.16 g), absolute length (2.85 ± 0.11 cm), specific growth rate (0.85 ± 0.03% day⁻¹), and daily growth rate (0.12 ± 0.01 g day⁻¹) compared to other groups. Additionally, Group P2 exhibited the highest survival rate at 100% and the highest digestive enzyme activities, with amylase at 7.24 ± 0.14 U mL⁻¹, lipase at 0.37 ± 0.01 U mL⁻¹, and protease at 0.69 ± 0.01 U mL⁻¹. The second-best performance was observed in Group P1, followed by P3, P5, and P4. Shrimp was identified as the most effective natural feed for improving the growth performance and survival rate of glass catfish.

Sexual Dimorphism, Reproductive Biology, and Growth Patterns of Sumatran Combtail (Belontia Hasselti, Cuvier 1831) From the Kelekar River, South Sumatra, Indonesia
ABSTRACT
Sexual dimorphism, reproductive biology, and growth patterns are fundamental knowledge in fisheries studies. This
study aimed to analyze the sexual dimorphism, reproductive biology, and growth patterns of Belontia hasselti. Samples
were collected in the Kelekar River, South Sumatra, Indonesia. Traditional fishing gear, specifically fish traps (“bubu”
and “pengilar”), was used to catch fish samples. The samples were transported to the Basic Fisheries Laboratory of the
Universitas Sriwijaya for collecting study parameters. A total of 100 B. hasselti were used in this study: 56 males (TL:
8.00-13.24 cm, BW: 9.50-37.49 g) and 44 females (TL: 8.00-13.99 cm, BW: 9.00-38.99 g). The results showed that there
were morphometric differences between male and female B. hasselti in CFL, AFL-1, AFL-2, VF-AF, and PrDL characters,
but there were no differences in meristic characters. The HSI ranged from 0.46% to 2.71% for males and from 0.57%
to 3.30% for females. The GSI for males ranged from 0.05 to 0.57%, while for females it ranged from 0.35 to 11.09%.
The gonadal maturity stage for males ranged from I to IV, while for females it ranged from II to V. The sex ratio was
1.19:1.00 (male: female). Fecundity ranged from 1011 to 4370 eggs. Egg diameter ranged from 0.8 to 1.7 mm. The
growth pattern of males was positively allometric (y = 0.0125x3.0987, R2 = 0.8182), while females exhibited negatively
allometric growth (y = 0.0596x2.4031, R2 = 0.7942). These findings are highly valuable for the implementation of the B.
hasselti breeding program.
