Abstract
The present study reports the length-weight relationship of male and female Anabas testudineus (Bloch) of Deepar Beel (wetland) of Assam. The fishes are separated into both male and female for calculation of length weight relationship and relative condition factor. The growth performance of length-weight relationship are found high since the correlation coefficient ‘r’ exhibits high degree of relationship with positive allometric correlation in both male and female Anabas testudineus. The Kn value of Male Anabas testudineus ranges between 0.79 and 1.42 with an average of 0.98±0.13 while in female it ranges between 0.71 and 1.29 with an average of 1.02±0.11. The relative condition factor in male is observed to increase from lighter to heavier fish. However, in female the relative condition factor initially declines from lighter to heavier fish and exhibits the lowest value at medium sized fish and thereafter steadily inclines to get the highest value in bigger fish having size range of ±13 cm TL.
