Length-weight relationship and relative condition factor of Macrognathus aral (Bloch and Schneider, 1801) from Deepor Beel of Guwahati, Assam


Author(s): Parag Deka and Himakshi Priyadarshini Barman

Abstract: The present study deals to calculate the length-weight relationship and the relative condition factor of a fish species Macrognathus aral (Bloch and Schneider, 1801) collected from Deepar Beel (wetland) of Assam. The fishes are separated into male and female to calculate the length-weight relationship separately along with relative condition factor (Kn). The growth performances estimated from the length-weight relationship are found high in both the sexes as the coefficient of correlation ‘r’ exhibits high degree of relationship. The positive allometric growth is shown by female whereas more or less isometric growth (b=2.99) by male. The positive allometric growth in female and isometric growth in male may be an indication for higher feeding proficiencies and better environmental as well as seasonal condition. The present findings also indicate that the value of ‘b’ in both the sexes is less deviated from 3.0, which is a constant for an ideal fish which suggest good environment and season for the fish to grow in the particular habitat. The Kn values in both the sexes are more or less similar which indicate good general condition of the fish.
