Abstract
Background and Objective: The growth of freshwater fish is influenced by several ecological and environmental factors. So the present study was aimed to provide baseline data on the length-weight relationship and condition factor of fish after changes in the hydrological regime of Lake Buyo. Materials and Methods: A total of 4696 individuals belonging to 13 families and 24 species were collected by using gill nets and traps, measured and weighed between June 2018 and May 2019. Length-weight relationship (LWR), Fulton’s condition (K) and relative condition (Kn) factors were analyzed from Standard Length (SL) and body weight (W). Results: Specimens exhibited length and weights varying between 2.4 and 53.6 cm (mean = 14.88±11.85) and 0.5-1278.0 g (mean = 177.18±311.70), respectively and the slope b value ranged between 2.149 and 3.341. Among all species, sixteen species showed negative allometric growth (Student’s t test, b<3), four species, isometric growth (b = 3) and four species, positive allometric growth (b>3). Condition factor K varied between 0.79±0.06 and 4.44±0.65 while Kn, between 0.49±0.08 and 3.47±0.43 and the majority of fish species (83%) had K>1.4, reflecting good condition in the study area. Conclusion: There was a significant relationship between length with weight and both condition factor for all species. Analysis of size structure indicated a reduction in the length of populations tested and among them, the growth type of seven species was changed compared to previous studies. It was concluded that changes in the hydrological regime would have an impact on the length and growth parameters of most fish.
