The first is the impact that the fishing has on these other species which inhabit the rays ecosystem is when rays are caught intentionally they are typically caught by <a href="/wiki/Longline_fishing" title="Longline fishing">longline fishing</a>. Longline fishing involves thousands of baited hooks on one very long fishing line close to the ocean's surface.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> These hooks draw many species including birds, marine mammals, fish, sharks, and rays. The second impact of stingray fishing and population decline is an ecological effect. The stingrays are keystone predators in coral reef environments, when these species are declined the other reef species are effected through trophic factors, for instance predator populations decrease therefore prey populations increase, and risk effects. Risk effects are the behavioral mannerisms that prey learn to avoid predators, such as where or when to feed without becoming a meal for a predator.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> Without predators such as stingrays, the behavior of prey species is altered. </p> <div class="mw-heading mw-heading2"><h2 id="Legislation">Legislation</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gill_plate_trade&action=edit&section=6" title="Edit section: Legislation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>It is currently illegal to trade <a href="/wiki/Manta_ray" title="Manta ray">manta</a> and <a href="/wiki/Mobula" title="Mobula">mobula</a> ray species without proper documentation that it is <a href="/wiki/Sustainability" title="Sustainability">sustainable</a> trade due to these species having been added to the <a href="/wiki/CITES" title="CITES">CITES</a> list.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> Once a species has been added to the CITES list it is internationally protected in legal trade;
