The fish can be up to a meter in length, but is rarely recognisable when served up. It makes up over 70% of the American canned tuna market (often called chunk light). Tuna chunks and flakes in brine or oil, on a sandwich, baked potato, or pizza? Safe bet its skipjack.<\/p>\n<p>It&#8217;s a pretty abundant species, but there are still issues around how it is fished. In particular, fishing methods indiscriminately harm other species, which end up as bycatch.<\/p>\n<p>Most skipjack is caught using large purse-seine nets. When these are set around <a href=\"https:\/\/www.youtube.com\/watch?v=VVbp7PijR6Y\"><span style=\"text-decoration: underline;\">Fish-Aggregation-Devices<\/span><\/a> (or FADs, which are really<\/p>\n<p>just floating structures that act like fish magnets) they result in <a href=\"http:\/\/vimeo.com\/18620636\"><span style=\"text-decoration: underline;\">huge amounts of bycatch<\/span><\/a> of other fish, as well as sharks, rays, even seaturtles, and, occasionally, whales or dolphins. Using FADs has been shown to increase the amount of bycatch tenfold.<\/p>\n<p>The famous dolphin safe logo on tuna may tell you that its not caught in a way that <i>deliberately<\/i> catches or sets nets around dolphins, but its no guarantee. And of course, &#8216;dolphin safe&#8217; tells you nothing about impacts on other species.<\/p>\n<p><div id=\"attachment_22184\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.greenpeace.org\/static\/planet4-usa-stateless\/2024\/11\/6e4d9b88-purseseiner1.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-22184\" class=\"size-full wp-image-22184\" src=\"https:\/\/www.greenpeace.org\/static\/planet4-usa-stateless\/2024\/11\/6e4d9b88-purseseiner1.jpg\" alt=\"A net bulging with tuna and bycatch on the Ecuadorean purse seiner 'Ocean Lady', which was spotted by Greenpeace in the vicinity of the northern Galapagos Islands while using fishing aggregating devices (FADs).\" width=\"600\" height=\"400\" \/><\/a><\/p>\n<p id=\"caption-attachment-22184\" class=\"wp-caption-text\">A net bulging with tuna and bycatch on the Ecuadorean purse seiner &#8216;Ocean Lady&#8217;, which was spotted by Greenpeace in the vicinity of the northern Galapagos Islands while using fishing aggregating devices (FADs).<\/p>\n<\/div>\n<p>Sadly, many of the species caught and killed as bycatch are endangered including several species of <a href=\"http:\/\/www.iucn.org\/?3362\/Third-of-open-ocean-sharks-threatened-with-extinction\"><span style=\"text-decoration: underline;\">open ocean sharks<\/span><\/a> and <a href=\"http:\/\/www.seeturtles.org\/1127\/turtle-threats.html\"><span style=\"text-decoration: underline;\">sea turtles<\/span><\/a>.

The package should tell you what species it is (if it doesnt, dont buy it!).<\/p>\n<p>Like skipjack, yellowfin are caught with purse seines, and when FADs are used the vast majority are young yellowfin that never get a chance to breed. Another method of catching them is using longlines: lines of baited hooks that can be many miles long. This method of fishing can be very indiscriminate and responsible for lots of bycatch sharks, swordfish, turtles, <span style=\"text-decoration: underline;\">and seabirds <\/span>can all fall victim to the baited hooks.
