Abstract/Overview A 16-week field experiment was carried out at Kaaka fish farm in Namutumba district to investigate the effect of dietary carbohydrate sources on the growth performance of Nile tilapia, Oreochromis niloticus L Fish fry of an initial mean standard length (SL) of 2.4cm were randomly introduced into experimental 12 pond units. They were subjected to three different test feeds possessing different sources of dietary carbohydrate namely maize bran (MB), cassava peels (CP) and ...
Abstract/Overview Developing countries are endowed with abundant natural resources. They are also more reliant on natural resources given their limited technology and inadequate infrastructural development. Despite the abundance of such resources, many rural communities are struggling over access to natural resources including fish. Fishing households are faced with ever-declining fish catches and combined effort of overexploitation. The impacts have been severe, especially among small sc...

Run-off containing a number of chemical solutions, which include herbicides, effluents, find their ways into the water bodies with a resultant negative effects on the aquatic ecosystem. This study sought to establish the effects of herbicide widely used in eradicating aquatic weed; Dizensate glyphosate (N- phosphonomethyl glycine) on Fingerlings of African catfish (Clarias gariepinus). The four day static bioassay was used to determine the median lethal concentration (LC50) and the value was ...
