چکیده
|
Present study describes the length-weight (lwr) and length-length (llr) relationships of a freshwater catfish eutropiichthyes vacha hamilton from indus river, sindh, pakistan. a total of 281 specimen of e. vacha were collected from fisherman’s catch from february 2005 to january 2006, are used for this study. the parameters a and b of the length-weight relationship were calculated as w= alb are presented. the values for allometric coefficient b of the lwr were close to isometric value for male (b = 3.159) and combined values for both sexes (b = 3.053). however, it suggested negative allometric growth for females (b = 2.973). results for llrs indicated that these are highly correlated (r2 > 0.9) p < 0.0001.
