Environmental Determinants Influencing Fish Community Structure and Diversity in Two Distinct Seasons among Wetlands of Northern Region (Ghana)

open access: yesInternational Journal of Ecology, Volume 2016, Issue 1, 2016., 2016
Fish community structure was assessed in six wetlands using cast nets, to correlate with environmental variables with diversity and distribution patterns, from 2010 to 2012. A total of 2,239 individuals belonging to 44 species and 1,938 individuals belonging to 40 species were sampled in the dry and wet seasons. Mochokid and Mormyrid families dominated

Fishes of the Alitash National Park: Taxonomic Accounts with Identification Keys of Fish in Floodplain Rivers of Abbay and Tekeze Basins, Ethiopia

open access: yesJournal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Ethiopia has considerable freshwater potential. Currently, the recognized fish diversity in the country’s freshwater ecosystem is more than 200. Despite the presence of such high fish diversity with considerable economic returns, ichthyofaunal studies on Ethiopian rivers are scarce. Thus, this study aimed to identify and compare ichthyofaunal diversity
