International Journal of Information Communication Technologies and Human Development Volume 9 • Issue 4The wide spread of mobile phones to many actors of aquaculture value chain have brought a new opportunity for enhancing access to aquaculture advisory and extension service in developing countries. Despite the potential shown by mobile phones in provision of other social economic services to both rural and urban communities, there are few studies presented how these tools facilitate access to aquaculture extension service among aquaculture farmers in the country, Tanzania. This article assesses how mobile phones can facilitate the provision of aquaculture extension service among aquaculture farmers in Tanzania. The article establishes an understanding on how aquaculture extension service is provided to aquaculture farmers through mobile phones using UshauriKilimo. UshauriKilimo is an agro-advisory and extension system which is now in use for more than two years. The article contributes to the existing body of knowledge with respect to ICT mediated aquaculture extension.
