Abstract Conservation efforts have raised awareness about the impact of small-scale fisheries on distribution seagrass plants. The patterns recovery Zostera noltei and commercial bivalves Cerastoderma edule , Ruditapes decussatus philippinarum after shellfish harvesting were studied in a field experiment bed NW Spain. Sample plots subjected to single disturbance two types treatments three zones characterized by different frequency density. photosynthetic efficiency (F v /F m ), shoot density, leaf length carbohydrate content Z. monitored every months during one year, C N leaves biomass plants measured year disturbance. abundance adults, juveniles recruits condition index adult quantified experimental harvesting. Shoot density remained low ten but recovered control values year. Carbohydrate contents apical rhizomes lower disturbed (treated) plots, whereas no effect was observed F . Denser more complex patches faster. below size while adults size, did not vary, indicating that hampered pressure. findings also suggest meadows can recover within if areas are rotated dense preserved.
