The detected levels are highly variable, with very frequent co-contaminations. <\/strong><\/p>\n<p>Beyond their presence, the review lists the differentiated biological effects according to the mycotoxins:<\/p>\n<ul>\n<li>Deoxynivalenol (DON): mainly associated with a decrease in feed intake and a reduction in growth (up to 20\u201330%). It also disrupts intestinal integrity and induces an inflammatory response. <\/li>\n<li>Fumonisins (FB): involved in metabolic disorders and liver lesions. They affect lipid metabolism and can impair growth and feed efficiency. <\/li>\n<li>Zearalenone (ZEN): known for its endocrine effects, it disrupts reproductive functions and can alter hormonal balances, with potential impacts on reproduction and development.<\/li>\n<li>Zearalenone (ZEN): known for its endocrine effects, it disrupts reproductive functions and can alter hormonal balances, with potential impacts on reproduction and development.<\/li>\n<\/ul>\n<p>Transversally, several of these toxins contribute to immunosuppression (decreased lysozyme, complement alteration), an increase in oxidative stress, and increased susceptibility to diseases. The co-occurrence of mycotoxins amplifies these effects. <\/p>\n<p>Conclusion: the combination of high occurrence and specific effects depending on the mycotoxins makes their management a central issue in aquaculture. Even at low doses, their impact on fish growth, health, and robustness is significant. <\/p>\n<p>&nbsp;<\/p>\n<p><em>Reference : Bittner, Miko\u0142aj, Pawe\u0142 Brzuzan, and Maciej Wo\u017any. &#8220;Occurrence of mycotoxins in fish feed and its consequences for aquaculture with special regard to the role of insect products.&#8221; Mycotoxin Research 42.1 (2026): 20.  <\/em><\/p>\n<\/div>\n<div id=\"fws_66d8668cdd08c\" class=\"wpb_row vc_row-fluid vc_row inner_row\" data-midnight=\"\" data-column-margin=\"default\">\n<p>&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This paper, published at the beginning of 2026, confirms a high prevalence of mycotoxins in complete fish feeds: 70 to 90% of the samples analyzed contain at least one toxin,&#8230;<\/p>\n","protected":false},"author":3,"featured_media":17186,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[55,54,56,57,53],"tags":[],"class_list":["post-17191","post","type-post","status-publish","format-standard","has-post-thumbnail","category-fr-en","category-myco-news-en","category-myco-news-en-2","category-myco-news-en-3","category-myconews-en"],"_links":{"self":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts\/17191","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/comments?post=17191"}],"version-history":[{"count":0,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts\/17191\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/media\/17186"}],"wp:attachment":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/media?parent=17191"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/categories?post=17191"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/tags?post=17191"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
