Functional diets improve survival and physiological response of Atlantic salmon (<scp> Salmo salar </scp>) to amoebic gill disease
Abstract Amoebic gill disease (AGD) is a major challenge for the marine salmonid farming industry. This disease is caused by Paramoeba perurans , which is a parasitic amoeba that affects fish growth and survival. The present work aimed at improving Atlantic salmon ( Salmo salar ) diet formulation as...

Abstract Amoebic gill disease (AGD) is a major challenge for the marine salmonid farming industry.
