Seasonal changes in the oocytes of Freshwater Mollusc, Lamellidens corrianus (Lea).
Journal Title: International Journal of Biological Innovations - Year 2021, Vol 3, Issue 1
Abstract
Reproductive phenomenon in freshwater molluscs is less studied in comparison to marine ones. Seasonal changes in the oocytes due to maturation of female gametes and onset of breeding period show some changes. Freshwater bivalve, Lamellidens corrianus showed seasonal gametogenic changes that depend upon external factors like salinity, light, food and temperature. Present study highlights the spawning activity of freshwater bivalve, Lamellidens corrianus in different seasons. In current exploration, specimens were collected in all the three seasons and studied for micrometric analysis of female gonads to find out the seasonal differences. With the observation, the author concluded that in Lamellidens corrianus, environmental factors synchronized the gonadal development at an early stage in the process of adulthood so that spawning can be coordinated to achieve synchronous release of gametes.
