Abstract
Length- weight relationships parameters are useful in fisheries science to estimate weight of individual fish from its length. It can always be used for determination of condition indices and to compare life history and morphology of populations of given species. Parambassis ranga commonly called Indian glassy fish was investigated for the study of length-weight relationships (LWRs) from Ujani wetland, a dam constructed on Bhima river of Maharashtra state of India. During the study period of November 2021 to October 2022, total of 300 samples were collected from local fishermen and length-weight parameters were recorded in laboratory at Modern College, Ganeshkhind, Pune. The present study shows intercept (a value) of 0.0089. Slope (b value) was 3.2303 which lie in expected range of 2.5 to 3.5. The slope value was more than 3 i.e. above isometric growth value that indicates positive allometric growth of fish.
