This paper has attempted to show the contribution of Lake Victoria small-scale fisheries to poverty alleviation. Two districts in Mwanza region in the Lake Victoria Zone were identified for a field research. The two districts are Sengerema and Ilemela. The results show that during high catch season both fishers and fishing gear owners generated high incomes, although gear owners were relatively far better than fishers. This was true for both Sardines and Nile perch fisheries. For instance, during high catch season, 39 sardine fishers each generated monthly income that ranged between $300 and $1,100, and 18 further fishers each generated income that was below $300. However, during low catch season, the incomes generated were very low for both fishers and gear owners to an extent of not even recovering the variable costs. The scenario was different with Nile perch fishers, out of 53 fishers that were sampled, 44 fishers each generated net monthly income that was below $400 during high catch season and during low catch season, 46 out of 53 fishers each generated net monthly income that was below $200. Fishers were the hardest hit during low catch season. 展开更多
