Aquafeed generally takes 60-70% part in the input cost of aquaculture. In which, fish meal is generally used as one of the costliest ingredients as a protein source, which makes the feed more costly. In ornamental fish feed, pigment supplements are another cost-increasing ingredient. The experimental feed was prepared by replacing the fish meal and an artificial pigment with the nutrients of three vegetable waste and nutrient-rich blue-green microalgae Spirulina. Prepared feed (F-3) was given to the experimental fishes along with the control (F-2) feed and the commercially available ornamental feed (F-1). Goldfishes were used as an experimental fish and pigments were estimated at the initial phase of the experiment and compared with the pigments found at the end of the experiments at 450, 475 and 500 nm to know the effect of the given feed on the pigments of the fishes. As a result, higher pigments were found in fish fed on experimental feed (F-3) as it was 0.156 ±0.001 µg/g with compare to fishes fed on commercial (F-1) and control (F-2) feed as it was 0.057 ±0.001 and 0.040 ±0.001 µg/g at 475 nm. There was a high significant difference (P<0.05) was observed between the pigmentation of fishes from F-3 and F-1. The survival rate was found 100 % in all the fishes with active and healthy fishes in the fishes fed on the (F-3).
