    Description: The African catfish (Clarias gariepinus) is a commercially farmed fish in Uganda, second in importance after the Nile tilapia (Oreochromis niloticus). This catfish has gained rapid popularity in aquaculture because of its faster growth and higher pond yields attaining average weight of over one kg with pond yields as high as 3.0 kg/m2 in six months compared to an average weight of 500g and pond yields of 1.2 kg.m2 for the Nile tilapia

    Description: Intensification of aquaculture production in Uganda is likely to result into disease out-breaks leading to economic losses to commercial fish farms and associated natural aquatic ecosystems.This survey assessed health profiles of selected commercial fish farms and adjacent natural aquatic ecosystemsto identify fish diseases and parasites affecting Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus) in aquaculture systems in Uganda. Fish farmsencounter disease out-breaks that cause low survival rates (0 - 30%), especially catfish hatcheries.Health management issues are not well understood by fish farmers, with some unable to detect diseased fish. Current control strategies to control aquatic pathogens include use of chemotherapeutants and antibiotics. Bacterial pathogens isolated included Flavobacterium columnare,Aeromonas sp., Edwardsiella sp., Psuedomonus sp., Steptococcus sp., Staphylococcus sp., Proteus sp.,and Vibrio sp. A high occurrence of Flavobacterium columnare exists in both asymptomatic andsymptomatic fish was observed. Parasites included protozoans (Ichthyopthirius multiphilis,Trichodina sp. and Icthyobodo sp.) and trematodes (Cleidodiscus sp. and Gyrodactylus sp.). Diagnosisand control of diseases and parasites in aquaculture production systems requires adoption of a regional comprehensive biosecurity strategy: the East African (EAC) region unto which this study directly contributes.
