| Abstract This study aimed to the water quality in the Nile tilapia aquaculture by testing a developed feeding system. This system featured a feeding unit positioned at the bottom of the tank, referred to as a feeding trough. The experiment utilized six fiberglass tanks, each with a diameter of 0.8 m and a height of 0.6 m, resulting in a water column height of 0.4 m. Three of the tanks were supplied with feed via a conventional automatic feeder, while the remaining three utilized the newly developed feeding system. A total of 150 fingerlings, each with an initial weight of 13.50 grams, were randomly distributed to the tanks at a density of 25 fish per tank, of fish per tank. Throughout the duration of the experiment, water quality indices were regularly measured and recorded. The results indicated a significant difference (P<0.05) between the two treatment in water quality, growth rate, and economic efficiency observed in the fish that were fed using the developed automatic feeder. | ||
