Length- Weight relationship and relative condition factor of Peacock eel (Macrognathus aral (Bloch and Schneider, 1801) from Dora Wetland of Assam

Abstract

Macrognathus aral (Bloch and Schneider, 1801) commonly known as peacock eel belongs to the family Mastacembelidae. The present study describes the length-weight relationship of the fish collected from Dora Beel. A total of 94 specimens were investigated in the study. The fishes were separated into male and female to calculate length- weight relationship of each individual of the species. The growth performance in both male & female are found high since the correlation co-efficient ‘r’ exhibits high degree of correlation between the length-weight relationships. The correlation co-efficient ‘r’ in Macrognathus aral is closer to 1.0. The length-weight relationship showed a positive allometric growth in both sexes of this species.
