Spatio-temporal distribution of Labeobarbus species in Lake Tana


Author(s): Takele Shitaw, Shewit G Medehin and Wassie Anteneh

Abstract: This study was conducted from May to December 2016 and the aim was to investigate the spatio-temporal distribution of Labeobarbus species of Lake Tana. Descriptive statistics was used to present the data. Chi-Square Test was used to compare the spatial variations of species between areas, the temporal variations between seasons. Labeobarbus intermedius was the most dominant specie, containing 38.8 % of catch followed by L. tsanensis, L. platydorsus, L. brevicephalus within a catch composition of, 18.96%, 13.1%, 10.5%, respectively. Labeobarbus dainellii and L. gorguari were rarely collected. Labeobarbus species of Lake Tana showed significant variation in catches at four sampling sites (p<0.01) and also these species showed significant variation in dry and rainy seasons (p<0.01). L. intermedius, L. tsanensis, L. brevicephalus, L. nedgia, L. gorgorensis, L. truttiformis were significantly more abundant in rainy season than dry season. The maximum possible diversity of four sampling site. The highest ‘J’ value was obtained at Gumara site with the value of 0.5. Effort control regulations, limiting the gillnet fishery in spawning seasons and/or areas, will be appropriate to prevent the Labeobarbus fish species of lake Tana.
