PROXIMATE COMPOSITION OF FOUR IMPORTED AQUARIUM FISH FEEDS IN BANGLADESH

Abstract

The study was conducted to estimate proximate composition of four aquarium fish feeds optimum, Osaka 2000, Osaka green and super nova which are available in different feed markets of Chittagong, Bangladesh. Chemical analyses of the samples were carried out in triplicate for dry matter (DM), moisture, ash, crude protein (CP), crude fiber (CF) and ether extract (EE) in the animal nutrition laboratory, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh during March to September, 2014 were collected, compiled and analyzed. Results indicated that , there were wide ranges of variations in chemical compositions for different parameters. DM contents varied from 95.4 to 93.5 g/100g and CP contents varied from 28.5 to 23.3 g/100g. similarly CF contents varied from 5 to 3.5 g/100g and EE contents varied from 6 to 4.4 g/100g. TA varied from 7.5 to 5.9 g/100g. It was concluded that, chemical composition of four estimated ornamental fish feed is widely variable. In this study no significant (p>0.05) relations were found in biochemical composition of the collected four feed samples. Nutritional quality of the aquarium fish feed was qualified to some extent to meet the minimum requirement of the aquarium fish. There should be a monitoring cell from the government to assess the quality of this expensive imported feeds for aquarist
