<h4>Introduction to Turtle Excluder Devices (TEDs)</h4><p><strong>Turtle Excluder Devices (TEDs)</strong> are specialized mechanisms designed to prevent the accidental capture and drowning of sea turtles in fishing nets, particularly <strong>trawls</strong>.</p><div class='info-box'><p>A <strong>trawl</strong> is a large, cone-shaped fishing net that is towed by a boat through the water, primarily used for catching fish.</p></div><h4>Mandate in Odisha for Turtle Protection</h4><p>The state of <strong>Odisha</strong> in India has taken a significant step by mandating the use of <strong>TEDs</strong> in all fishing <strong>trawls</strong> operating in its coastal waters.</p><p>This mandate aims to reduce the accidental deaths of sea turtles, especially the endangered <strong>Olive Ridley turtles</strong>, which are known to nest along the Odisha coast.</p><div class='key-point-box'><p>The implementation of <strong>TEDs</strong> is crucial for mitigating <strong>bycatch</strong>, which refers to the incidental capture of non-target species during fishing operations.</p></div><h4>Turtle Tagging for Conservation Research</h4><p>In addition to <strong>TEDs</strong>, conservation efforts include the <strong>tagging</strong> of sea turtles, particularly <strong>Olive Ridley turtles</strong>.</p><ul><li>These tags are made of <strong>non-corrosive metal</strong> to ensure durability in marine environments.</li><li>The primary purpose of <strong>tagging</strong> is to <strong>track their movements</strong> and to <strong>safeguard their habitats</strong>, providing vital data for conservation strategies.</li></ul><h4>Rushikulya River: A Critical Olive Ridley Nesting Site</h4><p>The <strong>Rushikulya River</strong> plays a pivotal role in the life cycle of <strong>Olive Ridley turtles</strong>, serving as one of the largest mass nesting sites globally.</p><div class='info-box'><ul><li><strong>Origin:</strong> <strong>Rushyamala hills</strong> in the <strong>Eastern Ghats</strong>, <strong>Kandhamal district</strong>, <strong>Odisha</strong>.</li><li><strong>Flow:</strong> Southeast, discharging into the <strong>Bay of Bengal</strong>.</li><li><strong>Tributaries:</strong> Includes <strong>Padma</strong>, <strong>Boringanalla</strong>, <strong>Joro</strong>, <strong>Badanadi</strong>, <strong>Baghua</strong>, <strong>Dhanei</strong>, and <strong>Ghodhado</strong>.</li><li><strong>Delta:</strong> Notably, the river <strong>has no delta at its mouth</strong>.</li></ul></div><div class='exam-tip-box'><p>Understanding the geography of key nesting sites like <strong>Rushikulya</strong> is important for questions related to biodiversity hotspots and conservation efforts in <strong>UPSC Prelims Geography</strong> and <strong>Environment</strong> sections.</p></div><h4>Global Recognition for Indian Turtle Conservation</h4><p>Indian biologist <strong>Shailendra Singh</strong> received the prestigious <strong>Behler Turtle Conservation Award</strong>, often referred to as the <strong>“Nobel Prize” of turtle conservation</strong>.</p><p>This award acknowledges his exceptional efforts in saving three critically endangered turtle species from extinction:</p><ul><li><strong>Northern River Terrapin</strong></li><li><strong>Red-crowned Roofed Turtle</strong></li><li><strong>Black Softshell Turtle</strong></li></ul><div class='key-point-box'><p>This recognition highlights India's significant contributions to global turtle conservation and the dedication of its wildlife biologists.</p></div>
