      Abstract
      Development of ornamental fish in Indonesia progressing steadily risen, largely a freshwater fish native to Indonesia. Color as the aesthetic value of ornamental fish will affect the economic value, then the color should be improved and maintained the quality is one of them through the engineering of feed nutrients. The color of fish caused by the presence or chromatophore pigment cells present in the dermis on scales, outside and under the scales. Red or yellow is the color that dominated much of the ornamental fish. The main components forming the red and yellow pigments are carotenoid pigments. Astaxanthin is a carotenoid molecule that predominantly found in fish. The addition of color-enhancing resources in fish feed would result in an increase in the color pigments in the fish's body, at least the fish are able to maintain the color pigment in the body during the maintenance period. One example of the raw materials that contain astaxanthin is rebon shrimp. Shrimp rebon flour containis materials such as minerals, proteins, khitin and carotenoids.
       
      Perkembangan ikan hias di Indonesia mengalami kemajuan yang terus meningkat, terutama ikan hias air tawar asli Indonesia. Warna sebagai nilai estetika ikan hias akan mempengaruhi nilai ekonomisnya, maka warna harus dapat ditingkatkan dan dipertahankan kualitasnya salah satunya melalui rekayasa nutrisi pakan. Warna pada ikan disebabkan oleh adanya sel pigmen atau Chromatophore yang terdapat dalam dermis pada sisik, di luar maupun di bawah sisik. Warna merah atau kuning merupakan warna yang banyak mendominasi ikan hias. Komponen utama pembentuk pigmen merah dan kuning ini adalah pigmen karotenoid. Astaxanthin merupakan molekul karotenoid yang dominan terdapat pada ikan. Penambahan sumber peningkat warna dalam pakan ikan akan mengakibatkan adanya peningkatan pigmen warna pada tubuh ikan tersebut, minimal ikan mampu mempertahankan pigmen warna pada tubuhnya selama masa pemeliharaan. Salah satu contoh bahan baku yang mengandung astaxanthin adalah udang rebon.
