Fish Species Diversity in Major River Basins of Ethiopia: A Review Tadlo Awoke Mengesha Department of Animal Science, College of Agriculture, Wollo University, Desse, P.O. The rich diversity of fish (33,000 species) is due to the diversity of aquatic habitats and the range of water quality in which they can live. The basic knowledge of diversity through species discovery and description is mostly complete for some areas of the world and for many families of fishes, but important gaps remain.

The Diversity of Fishes is a comprehensive, world-wide look at fish, including diversity and distribution, taxonomy, physical adaptations, behavior, role in food webs, importance to humans and their current status vis-à-vis habitat degradation and overexploitation. In this study, the species diversity of fish was indicated by the Simpson Index (Magurran 1988) represented as Ds = 1 â [Î£n i (n i - 1)] / [N(N-1)] where n i is the number of individuals in the i-th species and N is the total number of individuals. LMM results (Table 3) showed that fish species diversity, lake maximum depth, maximum temperature, ecoregion and the interaction between species diversity and ecoregion were significant predictors of the variation of fish size diversity. A total of 145 individuals of fish representing 24 species belonging to 14 families were caught during the study period. vision of Fish and forts for non - The study depicted presence of 19 species contributing about 55.88% of total fish diversity published from western Doon valley (Mehta and Gupta, 2007) and about 40.4% of total fish species from entire doon valley (Singh, 1964). For example, grasslands with a greater variety of native plants are more resistant to drought. Find out why thatâs not a simple question, and how ichthyologists determine how to classify members of the largest and most diverse of all vertebrate groups.
