Abstract

Decline in body coloration intensity in molly fish (Poecilia sphenops) is a common issue in ornamental fish aquaculture, primarily caused by a reduction in pigment concentration. Carotenoids, particularly β-carotene, are known to enhance fish coloration. Oil palm (Elaeis guineensis), especially its mesocarp, contains significant amounts of β-carotene and has potential as a natural source of pigment in fish feed. This study aimed to evaluate the effect of β-carotene extract derived from oil palm on the color intensity of molly fish and to determine the optimal dosage for improving color quality. A non-parametric Completely Randomized Design (CRD) was employed, consisting of four treatments with two replications: A (0% β-carotene), B (10% β-carotene), C (20% β-carotene), and D (30% β-carotene). Molly fish used in the study had an initial average Total Color Fidelity (TCF) score of 16, with a stocking density of six fish per aquarium. The main parameter observed was the increase in color brightness. Results indicated that the addition of β-carotene extract significantly enhanced the color intensity of the fish, with treatment D (30% β-carotene) yielding the highest improvement, reaching an average TCF score increase of 18.33 points. In conclusion, supplementation of oil palm-derived β-carotene extract in the diet effectively improves the coloration of molly fish, with 30% β-carotene identified as the optimal dosage for achieving significant color enhancement.

Abstract

Freshwater ornamental fish such as guppies (Poecilia reticulata) are popular due to the variety and vibrancy of their body coloration. However, one of the main challenges in their cultivation is the decline in color quality caused by pigment loss, which reduces their visual appeal. Lighting, particularly from artificial sources such as LED lamps, plays a critical role in influencing chromatophore activity involved in pigmentation. The appropriate spectrum, intensity, and duration of light exposure can enhance the brightness and clarity of fish coloration. Additionally, β-carotene, a precursor of carotenoid pigments, is essential for color enhancement. Oil palm (Elaeis guineensis), especially its mesocarp, is a rich natural source of β-carotene and has potential as a natural feed additive. This study aimed to evaluate the effect of combining LED light spectra with β-carotene extract from oil palm mesocarp on color intensity and reproductive performance of guppies. The experiment used a Completely Randomized Design (CRD) with four treatments and two replications: A (red LED + 20% β-carotene), B (yellow LED + 20% β-carotene), C (white LED + 20% β-carotene), and D (no LED + 20% β-carotene). The results showed that treatment C (white LED + 20% β-carotene) produced the best outcomes, with an increase in color score of 28.83 points (measured using Toca Color Finder) and an average of 45 offspring. These findings indicate that the integration of LED lighting and dietary β-carotene derived from oil palm is effective in enhancing both coloration and reproductive performance in guppies
