Study of absolute fecundity of Mystus carcio (Hamilton, 1822) of Puthimari River (Hajo) of Kamrup (R) District of Assam, India
Mystus carcio (Hamilton, 1822)is locally known as singorah in Assam (India) belongs to the order Siluriformes and family Bagridae. The present finding of Correlation coefficient ‘r’ between fecundity (F) and ovary weight (OW) shows the highest significant value (r=0.90, p<0.01) which was followed by F and body weight (BW) (r=0.68, p<0.01), and exhibits less significant positive Correlation coefficient between F and total length (TL) (r=0.60, p<0.01). It was also found that, the value of Correlation coefficient ‘r’ between F and gonadosomatic index (GSI%) (r=0.81, p<0.01) shows highly significant value. This little finding will help for commercial farming and induced breeding of this species in near future.
