Length–weight relationships of four small indigenous freshwater fishes from the subtropical Ganga River, India

Abstract

The basic informations on length-weight relationships for a number of small indigenous tropical freshwater species of fish are still scanty or not available on the FishBase. Present investigation reports the weight –length relationships of four teleost species from the river Gang in India. A total of 795 fresh fish specimens belonging to four species were collected from the four different locations along the stretches of the River Ganga from June 2017 to August 2018. The r2 and b values for the four fish species ranged from 0.949 to 0.998 and 2.55 to 2.849, respectively. For three of these species, length-weight relationships data represent the first information
