Seasonal Length-Weight Relationships and Condition Factors of Mystus tengara (Hamilton, 1822) in Two Habitats

Abstract

The aim of this study is to examine the relationship between length, weight, condition factor (K), and relative condition factor (Kn) of Mystus tengara (Hamilton, 1822), with special emphasis on seasonal variation of growth patterns, productivity, stocks, and conservation in two distinct ecosystems: pond and river. The results demonstrate that the species did not strictly adhere to the predicted cube law and had allometric growth patterns throughout the season.The condition factor (K) ranged from 0.33 to 1.49, the relative condition factor (Kn) varied from 0.44 to 1.77, and the 'b' values ranged from 2.00 to 3.29. The post-monsoon season saw the greatest average values for the regression parameter (b), condition factor (K), and relative condition factor (Kn). The r2 values represent a significant relation between length and weight in two habitats and throughout all seasons. The Pearson’s correlation indicates some positive and negative significant correlations among season, length, weight, condition factor, and relative condition factor in the study area (P<0.01 and P<0.05). The Post Hoc test indicates no significant habitat-based association between the same characteristics. However, there is a significant (P<0.05) seasonal link between relative condition factor, condition factor, weight, and length. As a result, these current findings will assist fisheries managers in creating efficient strategies for the long-term management of M. tengara in its habitats.
