ABSTRACT
The present study illustrates the inclusive information of morphological relationships, including morphometric parameters, meristic count, length-length relationships (LLRs), length-weight relationship (LWRs) and feeding biology of two threatened freshwater fish species, Glossogobius giuris and Nandus nandus from Sessa River, Dibrugarh, Assam. All the morphometric parameters revealed a proportional change with the increase in total length of the fish species. The growth coefficient ‘b’ in the LWR for both the fish speciesG. giurisand N. nandus exhibited values 0.900 and positively correlated with TL. The value of RLG for both the species was <1 which indicates the carnivorous nature of the fishes.
