    Description: 〈h3〉Abstract〈/h3〉 〈p〉The current fishing pressure in Lake Victoria, Tanzania indicates that the Nile perch (〈em〉Lates niloticus〈/em〉) is overfished and no regulations are enforced to maintain a sustainable fishery despite its significant contribution to the economy. This study examines the determinants of Nile perch overfishing and its intensity in Lake Victoria, Tanzania, using a double-hurdle model that is based on baseline survey data collected from 268 Nile perch fishers. The model analysed the data in two sequential hurdles, the first hurdle being whether or not a Nile perch fisher overfished (probability of overfishing), and the second hurdle being the difference between the actual average catch size and the minimum slot size of 50 cm total length (TL) (intensity of overfishing). The study revealed that different socio-economic, institutional and fishing effort influence Nile perch overfishing and its intensity in Lake Victoria, Tanzania. This, therefore, suggests that, to attain a balance between sustainable fishery management and the livelihood for Nile perch fishers in Lake Victoria, there is a need for the government to design policies that will consider the dynamics of the institutional setup and fishing effort in this lake.〈/p〉
