These change consist of a reduction of the biomass of longer lived fishes, particularly in shallower waters, and in conjunction with environmental fluctuation, the creation of opportunities for invasive species of fish (triggerfish Balistes caroline...

متن کاملA Survey of the Demersal Fishery in the Kigoma Area
Lake Tanganyika is the largest of the African rift lakes and the second deepest lake in the world (Coulter, 1991). It provides many critical services to communities in the four riparian countries of Tanzania, Zambia, D. R. Congo, and Burundi, and serves as an important source of protein through its vibrant fishery (Coulter, 1991). This fishery can be divided into two general categories based on...
