Abstract
This research was aimed to assess the suitability of Kijjude and Kala bays on Lake Victoria in Kalangala District for cage aquaculture. This study used a quasi-experiment research design. General environmental and physical data were collected and used to assess suitability of Kijjude and Kala bays for suitability for cage aquaculture by comparing the various measured parameters with the acceptable standards for cage aquaculture. Data were taken from a total of 14 and 6 points within Kijjude and Kala bays respectively. Systematic random sampling was used to determine the above mentioned sampling points. Kala bay was found to be suitable for both High Volume Low Density (HVLD) and Low Volume High Density (LVHD) cage. All sampled points within Kijjude bay were found to be only suitable for Low Volume High Density (LVHD) cage aquaculture except site KA whose depth was found to be less than 4.0 (m).
