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 ā€˜Jā€™ 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.
