“…As a result there is ten fold declines in number of specimens caught and of the Labeobarbus species; only one specimen of Labeobarbus macrophtalmus and none of Labeobarbus dainellii was found from the total catches of the study periods compared with a study in eight years time interval [4] . There has been also observed a significant species catch difference, which is more pronounced in Labeobarbus spp.…”

“…According to Goshu et al [4] , a total of 14 878 specimens, representing 18 species in three families were captured from the river mouth, open water and littoral habitats of the same sampling sites and duration of study periods as the present study and catch compositions by number was 77% and 13% for Labeobarbus spp. and O. niloticus and 9% and 1% for C. gariepinus and V. beso, respectively.…”

“…Contrary results from the present study (isometric growth) were obtained for Leptochondria cf. intermedius in Lake Awassa and by Goraw et al [4] in Lake Tana. It reported that the same phenomena of predominantly higher proportion of females in larger size classes was in another cyprinid fish Labeo horie (Heckel) in Lake Chamo.…”

“…the wetlands and the rivers) support unique endemic fish species of Lake Tana [4,5] . In Lake Tana, there is one cichlid, Oreochromis niloticus (O. niloticus) (Nile tilapia), which is the most widespread tilapia species in Africa.…”

“…As many other countries challenged in the world, population rise urbanization, agricultural development, industrialization and other water resource development activities have resulted in a decrease in the species diversity of freshwater fish species [2,3] . Potential threats to Lake Tana that hamper sustainable utilization of the fish resources include recession agriculture, silt load, pollution, drainage, water level fluctuation of tributary rivers and the lake itself, fishing on breeding seasons at breeding grounds by illegal fishing gears, over exploitation of specific fish species, deforestation of the surrounding area, overgrazing, population pressure end up with habitat degradation [4] .…”

Reviews in Fisheries Science & Aquaculture

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 Published and unpublished sources were used to obtain appropriate data.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.
