Endangered Oysters Plundered in Chicalim Bay

The endangered windowpane oyster, locally known as 'menddio', has reappeared in Chicalim bay after several years, bringing renewed hope to the community. However, this resurgence is shadowed by concerns over rampant, unregulated harvesting by individuals from distant areas, who are reportedly gathering vast quantities of the delicacy. This overexploitation poses a significant threat to the species' status as a vital brood stock in the bay, which is a key breeding site for various shellfish along India's west coast.

Conservation efforts, including guidelines issued by the Goa State Biodiversity Board (GSBB) in September 2022, aim for sustainable extraction. These guidelines advocate for restricted collection by locals within a 5-km radius, using traditional hand-picking methods, and imposing a closed season from July to October for breeding. However, local reports suggest these measures are being undermined, with harvesting activities described as "loot and plunder."

The Chicalim biodiversity management committee (BMC) is reportedly struggling to manage the influx of hundreds of collectors, especially on Sundays. Despite a request to the Vasco police for assistance in crowd control, their presence at the site has not materialized. Scientists have warned that the habitat faces threats not only from overexploitation but also from metal pollution and destruction, with an estimated 10,000 windowpane oysters harvested daily in Chicalim bay.

Community members and conservationists are advocating for stricter measures, including the establishment of 'no-take zones', to preserve the germ plasm of Goa's shellfish species. Locals have petitioned the government for a heritage tag for Chicalim village, believing it will bolster protection for this important bivalve habitat. The need for conservation is critical to ensure the rejuvenation of the broodstock and the overall biodiversity of the region.
