The extensive utilization of Mud Shells (Anodentia edentula) as a primary dietary source by the inhabitants of Kalangan Village, Central Tapanuli Regency, has led to a notable decline in the population of these shellfish. This decline is evident through the scattered presence of mud shells at research sites, coupled with frequent low tide shell-searching activities conducted by locals. Consequently, there arises a necessity for a scientific investigation to ascertain the density and distribution patterns of Mud Shells, laying the groundwork for potential cultivation initiatives and the sustainable management of Mud Shell germplasm and mangrove ecosystems in the Kalangan area.
The study, undertaken in September 2020, adopted a purposive sampling approach utilizing the 1 x 1 m2 transect method during low tide. Findings revealed a density of 150 ind/m2 at Station I, absence at Station II, and 43 ind/m2 at Station III, with a clustering distribution pattern observed at Station I and a random pattern at Station III. The absence of Mud Shells at Station II, coupled with dissimilar distribution patterns across stations, suggests a decline both quantitatively and qualitatively in the abundance of these shellfish within the ecosystem. As such, urgent conservation and cultivation interventions are warranted to ensure the continued existence of Mud Shells in the future.
