Changes in Fish Diversity and Fisheries in Ziway-Shala Basin: The Case of Lake Ziway, Ethiopia

Abstract

Lake Ziway is an economically important lake in the country. However, the physico-chemical parameters of the lake seem to be threatened by anthropogenic and climatic factors, which in turn affect biotic factors as reflected in fish catch. A study was made to assess the status and trends of fish diversity and fishery during October 2012 to September 2014 in Lake Ziway. Ten fish species were identified with low species diversity for the lake (H′ value of 1.67). The composition of the fishes has undergone some changes as compared to the last few decades.
