The study was carried out in 16 different regions of Keban Dam Lake (in Turkey) between 2002 and 2008. The data were taken from cooperative chairmen and members who carried out fisheries activities at the end of fishing season. The amounts of produced fish were evaluated according to fishing season, fisheries place and fish species. The fish were caught 483 tons during the 2002-2003 fishing season, 825 tons during the 2003-2004 fishing season, 653 tons during the 2004-2005 fishing season, 775,7 tons during the 2005-2006 fishing season, 685 tons during the 2006-2007 fishing season and 688 tons during the 2007-2008 fishing season. The produced fish were composed of Capoeta spp. (% 39), Barbus spp. (% 29), Cyprinus carpio carpio (% 24,4), Squalius cephalus (% 3,8), Astacus leptodactylus (% 3), Alburnus mossulensis (% 0,6) and Acanthobrama marmid (% 0,2). The average 191 motor boats, 418000 m gillnets and 33665 crayfish fyke nets were used for a year. However it depends on the fishing season.
