Preliminary study of fulton’s condition factor (CF) and relative condition factor (Kn) of Macrobrachium assamense peninsulare from Rawasan Stream, Uttarakhand, India

Fultons’ Condition Factors (CF) and the Relative conditions factors (Kn) of the Macrobrachium assamense peninsulare were studied for an interval of one year (2013-2014) in Rawasan stream, Uttarakhand, India. The Kn was observed maximum 1.179 in October 2014 and minimum in 0.904 in January 2014 in male prawn. Whereas CF was observed maximum 1.969 in January 2014 and minimum 1.491 in October 2013. But in case of female prawn minimum value of Kn was found 0.572 in June 2014 and maximum 1.214 in October 2014, but CF value was observed minimum 0.802 in October 2013 and maximum 2.388 in June 2014. The conditions factors (Kn, CF) ranged from (0.572 to 2.388), showing that the Macrobrachium assamense peninsulare was in a good and stable environmental condition in its microhabitat.
