Reviving Ashtamudi: Early Signs of Clam Recovery Spark Hope

The ICAR–Central Marine Fisheries Research Institute's initiative in Ashtamudi Lake shows early signs of success with recovery of the short-neck clam population. Hatchery-produced seeds have led to increased spatfall and stock, prompting the institute to recommend a three-month fishery closure from December to ensure further growth and sustainability.

One year into the stock enhancement programme by the ICAR–Central Marine Fisheries Research Institute, Ashtamudi Lake's short-neck clam population is showing promising signs of recovery. Recent field monitoring data indicates evidence of spatfall and a slight increase in standing stock, offering hope for future revival.

In light of these encouraging developments, CMFRI has advised a three-month fishery closure starting December 1. This decision is aimed at safeguarding the spawning and early growth phases of the clams, crucial for their continued survival and prosperity.

Under the leadership of Dr. M K Anil, the institute introduced three million hatchery-produced clam seeds into the lake last year. The results have been significant, demonstrating the potential of hatchery-based stock enhancement as a sustainable management measure. However, environmental challenges like unscientific sediment extraction remain threats that need to be managed carefully.
