Length-Weight Relationships of The Asian Striped Catfish, Mystus Vittatus (Bloch, 1794) from the Northeastern State of India

Abstract

The length-weight relationship was estimated for Asian striped catfish, Mystus vittatus based on 219 samples collected from a wetland of Tripura, India during June 2020 to November 2020. The body weight of males varied from 7.9 gm to13.9 gms, whereas, it was 8 gm to 14.3 gms for the females. The total length ranges from 6.4 cm to 11.8 cm and 7.1 cm to 13.3 cm for the male and female sample, respectively. The estimated value of the intercepts (a) ranged from 1.980 to 2.034, and slope (b) ranged from 2.997 to 3.046 for males and females, respectively, which indicates positive allometric growth for female and negative allometric growth for male. The coefficient of determination (r2) values were 0.9515 and 0.9315 for males and females, respectively. The results revealed the existence of a significant positive correlation between length and weight of species.
