This study provides the first analysis of length-weight relationships (LWR), length-length relationships (LLR), and condition factors for nine fish species from Bakhira Wetland, Uttar Pradesh, based on 898 specimens collected via experimental fishing. Species studied include Puntius chola, P. sophore, Pethia ticto, Systomus sarana, Rasbora daniconius, Amblypharyngodon mola, Devario devario, Nandus nandus, and Channa punctata. Analyses assessed whether LWR followed isometric growth (b=3) and LLR showed linearity (b=1), alongside the calculation of condition factors (K, Kn, Ka) and regression parameters (a, b, R2). Three species (P. sophore, A. mola, S. sarana) showed isometric growth, three (P. chola, R. daniconius, C. punctata) positive allometric growth (b>3), and three (P. ticto, N. nandus, D. devario) negative allometric growth (b<3). Most species showed non-isometric LLRs (b≠1), except A. mola, S. sarana, and N. nandus. Condition factor K ranged from 0.832 (R. daniconius) to 1.606 (P. ticto); Kn from 0.999 (R. daniconius) to 1.008 (A. mola); and Ka from 0.35 (R. daniconius) to 1.805 (P. ticto). Results indicate interspecific differences in growth, likely influenced by diet or physiology, offering a valuable baseline for future biological studies, stock assessments, and conservation efforts in the wetland.

Analyses assessed whether LWR followed isometric growth (b=3) and LLR showed linearity (b=1), alongside the calculation of condition factors (K, Kn, Ka) and regression parameters (a, b, R2).
