| Abstract | Wedge clams in the genus Donax are crucial bivalves in the sandy beach ecosystem. They play a vital role in the local food chain and provide a source of income for coastal communities. This research aimed to estimate the direct income value and potential harvesting value of wedge clams. Economic data for direct income were collected through interviews with local harvesters, while potential value was assessed using biological surveys during spring and neap tides. The results identified three species: Donax faba, D. cuneatus, and D. incarnatus. Locals typically harvested clams based on size rather than species. The net income from harvesting amounted to 154,359.38 baht/year (averaging 9,079.96 baht/person/year). Regarding potential quantity, average densities during spring tide for D. faba and D. incarnatus were 11.6 ± 1.85 and 6.0 ± 1.21 ind/m2, respectively. During neap tide, densities were 2.13 ± 0.76 for D. cuneatus and 0.67 ± 0.28 for D. incarnatus. The estimated annual potential harvesting value for this beach area was 716,420.94 baht/year or 247.05 baht/m2/year. These findings highlight the importance of wedge clams to coastal communities and the necessity of their conservation for sustainable utilization. |
