“…niloticus (91-93 Wudneh, 1998). fisheries on the Labeobarbus stocks. According to Ameha and Assefa (2002) the number of fish sold on the local markets by these seasonal fishermen fluctuated between 2 MT (1992( , 1998( ) and 11-19 MT in 1993( and 1994 However, it is unclear if these fluctuations in marketed fish are due to differences in fishing effort by the seasonal fishermen, sampling effort by the researchers or represent actual changes in the size of the spawning populations. In Lake Victoria a similar indigenous cyprinid fishery, using barriers and basket traps along the rivers, did not have a particular deleterious effect on the Labeo and Barbus stocks (Ogutu-Ohwayo, 1990).…”

“…Ethiopia is depending only on inland water for capture fishery (Ameha and Assefa, 2004;Janko, 2014). The total fish production potential is estimated to be 51,481 tonnes/year (FAO, 2003;FAO, 2012).…”

The objective of this review was to investigate the fishery management problems and conservation challenges in Ethiopia. Published and unpublished sources were used to obtain appropriate data. More than 183 fish species were reported in Ethiopia. The production potential of these water bodies is estimated to be 51,481 tonnes/year. Of these, only 30% of them are being utilized. Utilization of fishery is based on the socio-economic factors, resource availability, and religious influence on fish consumption. Types of fishing gears, fishing methods, socio-economic factors, lack of facilities and infrastructure, ineffective administration setup, lack of expertise, land use around fish habitats, and lack of scientific data were observed as the major fishery management and conservation challenges. The demand for fishes is, however, double increasing. Thus, effective management setup, regular stakeholders follow-up, and encouraging the development of aquaculture are very important to sustain the resources and meet the demand for the product.

A 96 h static toxicity bioassay was carried out to examine fish responses and to determine the median lethal concentration (LC 50 ) of Balanites aegyptiaca stem bark extract on adults of Brycinus nurse, Labeobarbus bynni and Labeobarbus intermedius. Experimental fish were exposed to piscicide plant extract of 0.0 (control), 15.0, 17.5, 20.0, 22.5, and 25.0 mgL -1 . Fish exposed to these extracts except the control showed symptoms of toxicity including darting, agitated swimming, air gulping, loss of sensitivity and knockdown before death. These responses were much frequent and faster in L. bynni and L. intermedius. The 96 h LC 50 values for the different test fishes were 18.99, 20.72 and 20.72 mg L -1 for L . bynni, L. intermedius and B. nurse, respectively. Based on the present investigation, we can conclude that the application of B. aegyptiaca extract causes lethal toxic effects on different fishes even at low concentrations and hence, indiscriminate use of the plant for fishing should be discouraged and regulated in order to protect fish biodiversity lose in the Alitash National Park area.
