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 ۲۸۱ specimen of E. vacha were collected from fisherman?s catch from February ۲۰۰۵ to January ۲۰۰۶, 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 = ۳.۱۵۹) and combined values for both sexes (b = ۳.۰۵۳). However, it suggested negative allometric growth for females (b = ۲.۹۷۳). Results for LLRs indicated that these are highly correlated (r۲ > ۰.۹) P< ۰.۰۰۰۱. REFERENCES Agarwal, N.K.
