Publication Date : 07/02/2018
This paper reported on a new formulated fish feed pellet prepared by extrusion method and the effect towards water quality. The obtained pellets showed well combination of all ingredients using household waste such as fish waste, vegetables waste, chicken fats and used palm oil. As a result, the welldeveloped feed pellets exhibit remarkable improvement in preserving water quality compared to commercialize fish feed pellet. The new formulated fish feed pellet has low turbidity value and Biochemical Oxygen Demand (BOD) level which help in maintaining quality of water. Platinum-Cobalt unit has confirmed the low effect of new formulated fish feed pellet on water colour. It was found that the new pellet may slightly reduce the pH of the water at low composition of protein sources.
