Condition Factor as an Indicator of Growth and Feeding Intensity of Nile Tilapia Fingerlings (Oreochromis niloticus) Feed on Different Levels of Maltose

The present study describes the Length -Weight relationship (LWR), relative condition factor (k) and dietary maltose of the Nile tilapia fingerlings (Oreochromis niloticus) to determine the growth pattern. Five isonitrogenous and isocarloric experimental diets were formulated to contain different maltose levels (0.0, 20%, 25%, 30% and 35%). Triplicate groups of fish (30 fish per tank with an average body weight, of 2.1 ±0.2 g) were assigned to each diet. At the end of the experimental (after 8 weeks). Samples of Oreochromis niloticus were collected from the tanks and transported to the laboratory for analyses. Length weight relationship (LWR) was described by the equation: W = a L. The value of the regression co-efficient obtained b from the WLR was 0.82, 0.87, 0.93, 0.82 and 0.90, respectively. There was a significant correlation between length and weight, while the condition factor computed for Oreochromis niloticus were 1.64, 1.77, 1.74, 1.72 and 1.79, which indicated good health condition during the experiment and it is indicating an isometric growth, which is the desirable for fish of fish farm.
