Influence of environmental factors on migration patterns of Clarias gariepinus (BURCHELL, 1822) in Lake Edward watershed, Albertine Rift Valley, East Africa

The study aimed to determine the environmental factors influencing Clarias gariepinus migrations within Lake Edward watershed. 1,103 C. gariepinus were tagged seasonally with external T-bar Anchor tags and released at four estuarine sites between July 2011 and May 2012. Relocations of 115 C. gariepinus were determined between September 2011 and December 2013 within the lake watershed. Rainfall, water temperature, total dissolved solids and electrical conductivity were key environmental factors significantly (p
