ABSTRACT
The length-weight relationship of freshwater pearl mussel, Lamellidens marginalis (Lamarck, 1819) were collected and analyzed during the sampling months July 2020 to June 2021 from the River Burhi Gandak. The collected mussel specimens (n = 995) were found to be in the 30 to 80 mm shell length, and 3.1 to 36.7 g shell weight. The results length-weight relationship W= 0.495L2.504 and the calculated R2 value was 0.731. The growth pattern of freshwater mussel was found to be (b = 2.504) negatively allometric. The findings of the present study will provide a baseline data for the effective and efficient management of the freshwater mussel resources along the River Burhi Gandak, North Bihar, India.
