Abstract：In order to understand the reproductive biology of clam Potamocorbula laevis as an ecologically and economically important forage bivalve species found in intertidal zones and shallow marine mudflats in China, the condition index (CI), gonadal developmental histology, and sex ratio were investigated in the clam P. laevis collected monthly from in the Liaohe Estuary(E 121.857 4°,N 40.785 1°)from April to October 2023, and environmental factors including water temperature, salinity, and chlorophyll a concentration were monitored to analyze their relationships with the reproductive cycle. The results showed that the population had a single annual reproductive period, with spawning peak from late July to the end of September and concentrated and prolonged gamete release. The condition index was shown to be strongly correlated with gonadal developmental stages, and was used as an effective indicator of gonadal maturity. Water temperature and chlorophyll a concentration were identified as key environmental factors influencing gonadal development and reproductive strategy, with the expected sex ratio (1.00∶1.12) of 1∶1 ratio (P>0.05). The finding provided the first systematic report on the reproductive biology of P. laevis in the Liaohe Estuary, and scientific basis for its resource conservation and artificial breeding.
