In 1896, the population of this species peaked. In a single night, thirty boats brought in almost 3 tonnes of F\u00e9ra. Unfortunately, the intensive fishing that followed led to a fall in its value. At the markets in Lausanne, because there were no buyers and they could not be preserved, the F\u00e9ras were thrown in baskets into the sewers. <\/p>\n\n\n\n<p>10 years later, the population collapsed, with fishermen catching only one sixth of the previous quantities. This was due to overfishing, exacerbated by an epizootic (animal epidemic).<br>Despite a Franco-Swiss agreement set up to protect the F\u00e9ra, it disappeared in the 1920s. Frying then began using non-native whitefish (born elsewhere than in Lake Geneva) from North America, Russia, Scandinavia and Estonia. But it was the fry and eggs from the Pal\u00e9es, from Lake Neuch\u00e2tel, that were the most widely introduced into Lake Geneva.<br>Today's F\u00e9ra has morphological and genetic similarities with the one from Neuch\u00e2tel.<br>Shouldn't this F\u00e9ra be called something else?<\/p>\n\n\n\n<p>Information taken from the book 1000 ans de p\u00eache en Suisse romande.<\/p>","protected":false},"featured_media":4138,"template":"","mots-cles":[],"class_list":["post-4813","60_secondes","type-60_secondes","status-publish","has-post-thumbnail","hentry"],"acf":[],"ase":null,"_links":{"self":[{"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/60_secondes\/4813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/60_secondes"}],"about":[{"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/types\/60_secondes"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/media\/4138"}],"wp:attachment":[{"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/media?parent=4813"}],"wp:term":[{"taxonomy":"mots-cles","embeddable":true,"href":"https:\/\/asleman.org\/en\/wp-json\/wp\/v2\/mots-cles?post=4813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
