Skippers have confirmed that the bycatch, as well as the fuel consumption, have significantly decreased while maintaining the same catch rate.<\/p>\n<p>The device is a modified 8m shrimp beam trawl, in which the heavy bobbin rope has been replaced with 12 lightweight electrodes. A harmless, low-intensity electric field close to the seafloor selectively provokes a startle response in brown shrimp.<\/p>\n<p>The elevated footrope lets non-target species escape underneath the hovering trawl and collects the shrimp that jump up into the water column. This technique reduces bycatch volume by 35% and decreases seafloor contact by 75%. It has implications for a large number of shrimp fisheries around the world where bycatch is the biggest issue the industry faces.<\/p>\n<p>The principle has potential advantages in selectivity, \u2018green\u2019 fishing and fuel savings in bottom trawling.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In cooperation with the Belgian Institute for Agricultural and Fisheries Research (ILVO), MARELEC has successfully designed and installed its HV1 \u2018Hovercran\u2019 electronic fishing gear on multiple shrimp beam trawlers.<\/p>\n","protected":false},"author":2,"featured_media":811,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[8,15],"tags":[],"sponsor":[],"class_list":["post-810","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-electronics-communications","category-fishing-gear"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/810","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/comments?post=810"}],"version-history":[{"count":1,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/810\/revisions"}],"predecessor-version":[{"id":812,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/posts\/810\/revisions\/812"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/media\/811"}],"wp:attachment":[{"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/media?parent=810"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/categories?post=810"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/tags?post=810"},{"taxonomy":"sponsor","embeddable":true,"href":"https:\/\/www.worldfishing.net\/icefish-conference\/wp-json\/wp\/v2\/sponsor?post=810"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
