Effect Of Carrot Flour (Daucus Carota L.) Addition In Commercial Feed On The Color Brightness Level Of Molly Fish (Phocilia Sphenops)

Fisheries

This study aims to examine the effect of differences in the addition of carrot flour on the color intensity of molly fish. The research was carried out from January 2022 to March 2022 at the Aquaculture Laboratory, Building 2, Faculty of Fisheries and Marine Sciences, Padjadjaran University. This study used an experimental method and the experimental design used in this study was a completely randomized design (CRD) with four treatments and three replications. The treatments were control, without carrot flour (A), 3% carrot flour (B), 5% carrot flour (C), and 7% carrot flour (D). Maintenance with treatment on the test fish was carried out for 40 days. Parameters observed included color brightness observed using Toca Color Finder (TCF), growth, viability and water quality (DO, pH, and temperature). The results showed that the highest increase in fish color brightness was obtained in treatment C with the addition of carrot flour by 5% with a value of 1.8 on the head and 1.7 on the body. The water quality parameter values in treatment C (5%) with temperatures ranging from 25.2 -26.3⁰C, DO (Dissolved Oxygen) 6.1-7.3 ppm, and pH 7.03-7.86 were in which is good for the growth and survival rate of molly fish.
