Dropline

<h2 id="conservation-impacts">Conservation impacts</h2>
A concern for <a href="/facts/Marine_conservation/1YmDrFwq">marine conservation</a> is that droplines are able to access areas that are otherwise natural fish refuges, such as <a href="/facts/Deep_sea_canyon/GptxqPlX">deep sea canyons</a> and <a href="/facts/Seamount/jR3XQv2E">seamounts</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1">1</a>
The <a href="/facts/Australian_Marine_Conservation_Society/TmPnPVPV">Australian Marine Conservation Society</a> rates dropline fishing as having a "moderate impact" on wildlife and a "low impact" on marine habitats.<a class="footnote-ref" id="fnref:2" href="#fn:2">2</a>
Droplines have the potential to interact with <a href="/facts/Orca/AaDEqz8T">orcas</a> (killer whales). There is predation by orcas on commercial longline and dropline fish catches, including around <a href="/facts/Tasmania/q3dubPTt">Tasmania</a>,<a class="footnote-ref" id="fnref:3" href="#fn:3">3</a> <a href="/facts/Bering_Sea/xE9Gzouv">Bering Sea</a> and <a href="/facts/Prince_William_Sound/r1ChjsCX">Prince William Sound</a> areas,<a class="footnote-ref" id="fnref:4" href="#fn:4">4</a> causing significant financial loss to commercial fishers, and threat to orcas, which can become caught or entangled, exposed to ship strikes when moving or migrating, or suffer retaliation from fishers. Retaliation in response to predation on fish catches in previous decades has included shooting and harpooning of orcas.<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a><a class="footnote-ref" id="fnref:6" href="#fn:6">6</a>
