Growth and pigmentation development efficiencies in fantail guppy, Poecilia reticulata fed with commercially available feeds

Abstract

The commercial value of ornamental fish is primarily dependent on their external body colouration. Fade coloured fish fails to attract the interest of the buyers. In the present study an experiment were conducted to evaluate the efficacy of four types of feed (Living tubifex, Dried tubifex, Dried Daphnia and Prepared granulated feed) in the rearing of fantail guppy. Carotenoid content of the feed used, caudal fin and muscle of the fish and specific growth rate (SGR) of the fish were also analyzed. Results showed that the fantail guppy utilized the live organisms more efficiently than the artificial diet. Results are also encouraging because the fantail guppy became more brightly colourful which fed the carotenoid rich feed in comparison to the types of feed. Living tubifex was proved to be the best feed for guppy for increasing the growth and colouration.

Improved quality of color sumatra barb, Puntigrus tetrazona (Bleeker, 1855) with artificial feed enriched red spinach flour (Amaranthus tricolor L.)

“…Ikan asli Indonesia ini berasal dari pulau Sumatra, memiliki potensi untuk dikembangkan karena permintaan pasaryang cukup tinggi. Ikan sumatra albino memiliki warna dan corak yang menarik pada bagian tubuh berwarna kekuningan dengan empat pita tegak berwarna keemasan dan warna pada ikan hias sumatra albino merupakan salah satu faktor yang memengaruhi terhadap harga jual (Mandal et al 2010).…”

Sustainable aquafeed development: Incorporating select fruit wastes into Zebrafish diets using mathematical model-based approach

“…Ornamental fish cultivation is getting popular which received increasing demand. The growing of ornamental fish industry made it necessary to have a continuous supply of nutritionally proportioned and economical feed ( Kasiri et al, 2011 , Mandal et al, 2010 ). Feed cost and availability is a major limitation to aquaculture production ( Edwards et al, 2000 ).…”

Anaesthetic efficacy of eugenol on various size classes of angelfish (Pterophyllum scalare Schultze, 1823)

“…At the moment, the ornamental fish market is highly competitive and also demanding with considerably large market values to the extent that they are referred to as living jewels. Their tranquillity, small and colourful body along with astonishingly eclectic shape and behaviour made them popular aquatic pets (Mandal, Mukherjee & Banerjee ; Johny & Inasun ). Being native to Amazon region of South America including Peru, Colombia and Brazil, the angel fish, P. scalare is considered the most enviable ornamental fish mainly owing to its attractiveness, reproductive capacity, reasonable housing and nutritional requirements and adaptability to captivity (Garcia‐Ulloa & Gómez‐Romero ; Karayucel, Ak & Karayucel ; Froese and Pauly ).…”
