Summary

Hovedformålet med kontrollerede forsøg med pereddikesyre vandbehandling har været at videreudvikle en effektiv vandbehandlingspraksis, der ikke påfører fiskene unødigt stress. Vandbehandling med pereddikesyre (PES) fører ofte til kortvarige adfærdsændringer hos fiskene, og det er velkendt i erhvervet, at fiskene skal ”vænne sig til stoffet”. Der foreligger ingen undersøgelser, der har belyst effekten af PES på fiskenes velfærd ud fra mål for fysiologisk stress, ligesom effekten af doseringsformen er ukendt. Derfor blev der igangsat en undersøgelse med det formål at undersøge effekten af PES dosering på regnbueørreder.

Summary translation

The main objective with controlled studies with peracetic acid water treatment was to identify efficient water treatment practices that do not cause unnecessary stress to the fish. Water treatment with peracetic acid (PAA) often leads to short-term behavioral changes in fish, and it is well known within the industry that the fish need to acclimatize or get used to the chemical.
Studies investigating the effect of PAA on fish welfare from stress response perspective are needed, as well as studies on the effect of the dosage regimen (short term high dose vs. long term low dose). A study was conducted to investigate the effect of PAA dosage on rainbow trout under controlled experimental conditions.
