Studies on length-weight and length-length relationships of a catfish Eutropiichthyes vacha Hamilton (Schilbeidae: Siluriformes) from Indus River, Sindh, Pakistan
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.
