Summary, etc. <p>Seagrass ecosystems are lost due to habitat disturbance, coastal development or human activities. We report for the first time the impacts of boat anchors from traditional fishing and recreational activities on the seagrass <em>Halophila ovalis</em> from India. <em>H. ovalis</em> density, biomass, morphometrics, canopy height and percentage cover were estimated from two sites of Govind Nagar beach of Andaman and Nicobar Islands. <em>H. ovalis</em> shoot density was reduced by physical damage caused by boat anchors. <em>H. ovalis</em> morphometrics, such as number of leaves per ramet, leaf length, width and horizontal rhizome length were significantly reduced when impacted by boat anchors. Seagrass canopy height and percentage cover was reduced. Though the impact of boat anchors reported here is on small-scale, it may impact feeding grounds of locally endangered dugongs. Therefore, proper management and preventive measures should be implemented to prevent the loss of dugong grass habitats from tourism, recreational and fishing activities.</p>
