Type: article
Abstract: The purpose of this study was to calculate the length-weight relationship as well as the condition factor of a threatenedfreshwater climbing perch, Anabas testudineus (total length: 5-18cm; body weight: 12-58g) from Arrah (Bihar), India toassess the importance of allometric factor and well-being. From September 2022 to March 2023, a total of 458 fishspecimens were collected for this purpose. For the total fish, the length-weight relationship was calculated as y = 3.610x- 5.619 (logy = 1.836 logx - 0.430) with coefficient determination = 0.914. This indicates that the species' growth isnegative allometric and a statistically significant correlation (r) was calculated between the length and weight of thesampled fish. The coefficient determination (R2) ranges from 24-97% (r= 0.488-0.986) indicating a proper growthpattern. Fulton's condition factor values ranged from 1.346 to 3.613 indicating that the fish was in good health. Theaverage values of condition factor (K) of 2.00 and relative condition factor (K') of 0.999 indicate that its habitat is ingood condition. This study is useful in providing pertinent information for understanding fish biology, estimating fishconditions in its environment and assessing population dynamic parameters.
