Enhancement of Color Brightness on Clown Fish (Amphiprion percula) With Addition of Tomato Powder Extract

Abstract

The prospect of clown fish cultivation business is still being expanded to make profitable business activities and increasingly attract ornamental fish lovers. However, it is difficult to get clown fish with a good level of color brightness. So it can reduce the level of sales production. This study aims to determine the effect of the addition of tomato powder to increase the brightness of the color clown fish at the Ambon Marine Aquaculture Fisheries Center. The research was conducted from March to June 2020 at the Ambon Marine Aquaculture Fisheries Center. This study used a Completely Randomized Design (RAL) with 4 treatments and 3 replications. The treatment is to mix tomato powder in the feed with a concentration of 0 mg/gr (Treatment A), concentration 20 mg/gr (Treatment B), concentration 40 mg/gr (Treatment C), and concentration 60 mg/gr (Treatment D). The fish used is a clown fish with a size of 1 cm with a spread of 4 fish with a circulatory maintenance system. The observed parameters include the brightness of the clown fish color, which is measured using the color grab camera app, the growth of which is the average length and weight of average seeds measured using a ruler with a precision rate of 1 cm and a digital scale with a precision rate of 0.01gr and survival rate. The results showed that feeding with the addition of powdered tomato did not give a significant effect to increase the brightness of the color of the clown fish. However, it affects the growth (length and weight) and survival rate of clownfish seeds.
