Abstract

A total of 300 freshwater mussels Lamellidens marginaliswere sampled from the Ratargul Freshwater Swamp between December 2020 and November 2021 to investigate the relationships between length, weight, soft tissue wet parameters, sex ratio, condition indices, gonadal histology, and hydrological features of swamp forest habitat. The shell length and shell weight varied between 5.00 and 9.50 cm and 12.26–78.96 g respectively. The length at maturity Lm was recorded as 5.98 cm and the calculated value of χ2 suggested a dominant female stock at the study site (P < 0.05). The relationship between different morphometrics ofLamellidens marginalisand environmental parameters exhibits a very weak regression coefficient value (P < 0.05), suggesting a weak effect of seasonality on the growth metrics. Previtellogenic and vitellogenic oocytes were observed in the ovary, and mature spermatids were found in the testes in samples collected in the rainy season.
