Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 1
Abstract
This study describes the condition factor (K), gonadosomatic index (GSI) and relative length of the gut (RLG) of Carasobarbus luteus in Karkheh River. A total of 210 specimens were caught by using various mesh size of gill nets from July 2010 to July 2011. The maximum condition factor for males was in February 2011 and for females was in October 2010. Minimum condition factor for males was in January 2011 and for females was in July 2010. The highest gonadosomatic index (GSI) values were determined in April 2011 for both sexes while the lowest values were recorded in May 2011 for males and in August 2010 for females and spawning period were during in April to May. RLG index increased with increase in age and the mean of RLG index was 1.99±0.43.
