When water temperatures get too hot, fish can become stressed or even die. In rivers, Atlantic salmon and other cold-water species sometimes escape the heat by flocking to cooler areas, which often arise near groundwater springs or relatively cool tributaries.<\/p>\n<p>Lots of work has been done to preserve and augment these naturally occurring refuges, said Smith, of Dalhousie University in Halifax, Canada, \u201cbut there hasn\u2019t really been an emphasis or focus on if we can create cold-water habitat.\u201d So she and her colleagues pumped groundwater that was about 9\u00b0 Celsius (or about 48\u00b0 Fahrenheit) from a nearby well into the river, manifesting an artificial plume of water that could be as much as 20 degrees Celsius cooler than the surrounding water.<\/p>\n<p>The plume attracted several hundred fish of varying life stages and species, including Atlantic salmon and brown trout. Most were alevins \u2014 juvenile fish still attached to yolk sacs \u2014 that occupied the plume throughout the tests. But when a heat wave brought on maximum water temperatures of about 30\u00b0 C, more mature fish also took shelter in the plume. For a pump-free approach, the team also rerouted some water from the river into an underground trench, where it cooled before reentering the river. Though this method lowered the water temperature by only a few degrees Celsius, fish were observed frequenting the passively cooled flow throughout the summer.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.sciencenews.org\/article\/cold-water-river-salmon-fish-climate\">Science News<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/pumping-cold-water-into-rivers-could-act-as-air-conditioning-for-fish\/\">Pumping cold water into rivers could act as \u2018air conditioning\u2019 for fish<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[11992,575,1130,3229,11993],"class_list":["post-117945","post","type-post","status-publish","format-standard","hentry","category-news","tag-cold-water","tag-environmental-news-en","tag-fish","tag-salmon","tag-trout"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/117945","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=117945"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/117945\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=117945"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=117945"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=117945"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
