    Traditional Gillnet & Motorized Fisheries in Ethiopia and Loss of Biodiversity in Lake Tana (Its Implication to Food Security)
    (A.A.U, 2005-07) Ghirmai, Abraham; Aredo, Dejene (Dr.)
    Lake Tana is found in North West of the country & it is the biggest lake in the country. The lake is with higher potential & with unique fish fauna barbus. The fishery has started to develop with the help of foreign NGO' s. However, fish exploitation does not exceed 1500 ton per year. On the other hand, different studies & including this paper have shown that the catch is declining since 1997/98 in the inshore. This is because of social, economical & institutional factors. According to the secondary data & survey conducted, the lake is contributing to livelihood 3457 people of the surrounding people in different ways. However, the policy of the region is maximum sustainable yield but in practice it is an open-access (un controlled fishing activities). As the study shows considering the inshore the actual harvest is above the optimum catch in both motorized & reed boats. There is loss of biodiversity of the fishery due to the above mentioned factors. Therefore, the fishery management should use strategy which brings the fishing to the level of optimal by using command & control & economic incentives. The first one refers to licensing, gear restriction and close specific season etc & the second one refers to giving credit & tax imposing tax for in shore and minimum tax for offshore. Therefore, greater attention should be given in managing & appropriate use of there source before the stage of extinction reached. If it reaches extinction the socio-economic livelihood o fthe surrounding will be suffered. This leads to food self insufficient.
