Hvor mye antibiotika bruker havbruksn\u00e6ringen?<\/h1>\n

Havbruksn\u00e6ringen har v\u00e6rt gjennom en enorm utviklingen siden 80-tallet. I 1987 ble det brukt nesten 50 tonn antibiotika for \u00e5 produsere rundt 60 000 tonn fisk, og noe m\u00e5tte gj\u00f8res. Prosjektet \u201cFrisk Fisk\u201d startet, og 30 \u00e5r senere er bruken av antibiotika redusert med 99 prosent. Mindre enn \u00e9n prosent av laksen er n\u00e5 behandlet med antibiotika.<\/p>\n

En viktig grunn til nedgangen i antibiotikabruk er at vi har utviklet effektive vaksiner, som alle laks f\u00e5r n\u00e5r de er sm\u00e5. Norge har i dag noen av de viktigste fagmilj\u00f8ene i verden for utvikling av fiskevaksiner, og er et foregangsland med tanke p\u00e5 \u00e5 utvikle og ta i bruk vaksiner til fisk. Det utvikles stadig mer avanserte vaksiner. I 2017 tok Alsaker, som f\u00f8rste selskap i Norge, i bruk en DNA-vaksine mot pankreassykdom (PD) p\u00e5 Fjon Bruk i Sveio. Vaksinen gj\u00f8r at fisken selv lager antigen mot PD-viruset.<\/p>\n

Et annet bidrag for \u00e5 f\u00e5 ned antibiotikabruken er det systematiske arbeidet med avl. Det er avlet frem fisk som er mer motstandsdyktig mot sykdom og parasitter. Ogs\u00e5 rutiner og hygiene p\u00e5 havbruksanleggene har blitt bedre, og er med p\u00e5 \u00e5 holde medisinbruken lav.<\/p>\n
