Abstract
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.
