Peredikksyre som behandling av amøbegjellesykdom (AGD) i laks (PERAGILL) / Peracetic acid as a potential treatment for amoebic gill disease (AGD) in Atlantic salmon
AGD is a significant health and disease problem in Atlantic salmon aquaculture. Since the first documented case of AGD in Norway, the threats have been quite persistent and the number of reported cases is showing an upward trajectory trend. The industry must be kept abreast with sustainable treatment options to combat this emerging threat. The use of freshwater and oxidative disinfectant bathing are the two strategies being applied in commercial production. Peracetic acid (PAA), an organic peroxide, is being considered as a more sustainable disinfectant in aquaculture compared with other conventional disinfectants. PAA offers some advantages that may address the challenges in the currently available treatments for AGD. Given the escalating threat that AGD is posing to the Norwegian salmon aquaculture industry, there is indeed a big challenge to develop alternative methods that have the potential in addressing issues on efficacy, practicality and most importantly, sustainability. The documented features of PAA make it a good candidate to be explored as a treatment for AGD. The exploration of this potential must be provided with a complementary toolbox that will assess treatment impacts and success through insights from different biological perspectives.
• To assess the impact of PAA treatment on fish health and welfare (WP1).
• To determine the potential environmental risk of PAA treatment (WP2).
• To develop integrative assessment toolbox to evaluate treatment impacts and efficacy (WP3).
• To compare conventional AGD treatments with PAA application (WP5).
Dissemination of project results
The results of the study will be made available through print and online communication channels. All peer-reviewed publications will be distributed under Open Access scheme. Popular science articles, both in Norwegian and English, will be published in communication media that are highly relevant to the industry. The dissemination and communication channels of Nofima and of the partner institutions will be maximised.
The results are expected to be presented at national and international conferences/symposia as poster and/or oral presentations. Conferences organised by FHF and the Research Council of Norway (e.g., Havbruk and Friskfisk) are excellent opportunities to establish the credential of the project at a national level. At the international scene, conferences with close connection with the industry (i.e., Aquaculture Europe, World Aquaculture) are priorities for result dissemination.
