abstract
The present study was based on biometric growth parameters and their relationship in different fish species of family Bagridae from Harike wetland, a Ramsar site in Punjab. During the study period from March 2017 to November 2017, three major species of family Bagridae viz. Sperata seenghala, Sperata aor and Rita rita were encountered in fish catch from Harike wetland. Biometric growth parameters like- length-weight relationship (LWR), length-length relationship (LLR), condition factor (K) and relative condition factor (Kn) were analysed in all reported species of Bagridae. LWR showed negative allometric growth pattern in S. seenghala (b = 2.74) while isometric growth in S. aor (b= 3.02) and R. rita (b = 3.05). The length parameters revealed strong relationship between total length, standard length and fork length with correlation coefficient range of 0.89-0.99 in all reported species of Bagridae. Relative condition factor (Kn) value varied considerably from 1.65-1.73 while condition factor ranged from 0.45-1.31 which may be attributed to different environmental conditions of wetland. This study may serve as baseline information in formulation of action plan for management and conservation of these species.
