Numerical Analysis for Effective Transplant and Seabed Restoration for Recovery of Pen shell Resources in the Ariake Sea, Japan

T. Tabata, K. Hiramatsu, and M. Harada
Abstract—Numerical simulation was conducted in order to support the recovery of pen shell Atrina pectinata resources in the Ariake Sea, Japan. Larval transport model was used to predict migration of larvae drifting on tidal currents which were calculated using a two-dimensional depth-averaged model. 14 release points were defined as potential new spawning grounds for the pen shell. The number of larvae that migrated from these points to habitable areas for pen shells (depth: 2 < h < 20 m, grain size median diameter: >62.5  μm) was calculated for each release point. Consequently, larvae released from the northeast area (particularly from Point 13, Noku 210) reached the largest habitable area. In addition, most of the larvae ultimately drifted to Isahaya Bay, suggesting that transplanting pen shell in the northeast area and seabed restoration in Isahaya Bay would be the most effective approach to recovery of pen shell resources.
