  Diversity, relative abundance and some biological aspect of fishes in Gilgel Abay and Andassa Rivers were studied from September 2010 to June 2011 by using gillnets of mesh sizes 6 cm, 8 cm, 10 cm and 12 cm, monofilaments of different mesh sizes, cast net, hook and lines. Fish species identification was done by using literature and specimen deposited in the laboratory. Abiotic parameters such as temperature, conductivity, pH, total dissolved solids and transparency of the rivers were also taken, using multi-meters. The analysis of independent ttest showed that there was significant deference in pH and transparency between seasons in Andassa River (p<0.05). In Gilgel Abay River, there was significant difference in temperature and transparency (p<0.05) between seasons. Totally 939 fish specimens were collected from Gilgel Abay and Andassa Rivers. Three families and thirteen specie.. View More»
