Abstract
The objective of this research is to assess the length-weight relationship (LWR) as well as Fulton’s condition factor of freshwater catfish species i.e., Rita rita from Gomti River, Lucknow, Uttar Pradesh. A total of 319 fish specimens were randomly sampled from January 2022 to December 2022. The results revealed the values of ‘b’ for male, female, and pooled populations are 2.68, 2.73, and 2.70 respectively which represents negative allometric growth. The coefficient of correlation, ‘r2 ’ between total length and body weight for males, females, and pooled population were estimated as 0.931, 0.934, and 0.933 which is significant at a 1% level. The fish were found to be in good health condition, as the calculated value of Fulton's condition factor varied from 1.33 to 1.39. The present research is beneficial as it offers pertinent data for studying fish biology, assessing the condition of fish in their habitat, and evaluating parameters about population dynamics
