Abstract

Composition for treatment of mucus on fish gills for a therapeutic or a prophylactic treatment of an amoebic gill disease in fish, where the composition comprises an extruded fish feed supplemented with arginine; said fish feed comprising protein, binder, fat, vitamins and minerals; and a total arginine content of the fish feed is at least 3.0% (wt/wt) of a total feed weight.

1 . A composition for treatment of mucus on fish gills for a therapeutic or a prophylactic treatment of an amoebic gill disease in fish, characterised in that the composition comprises an extruded fish feed supplemented with arginine; said fish feed comprising protein, binder, fat, vitamins and minerals; and a total arginine content of the fish feed is at least 3.0% (wt/wt) of a total feed weight. 
     
     
         2 . The composition for use according to  claim 1 , where the treatment of the mucus comprises an increase of a viscosity of the mucus. 
     
     
         3 . The composition for use according to  claim 1 , where the treatment of the mucus comprises an increase of a content of a polysaccharide in the mucus. 
     
     
         4 . The composition for use according to  claim 1 , where the amoebic gill disease is caused by a marine amoeba. 
     
     
         5 . The composition for use according to  claim 1 , where the fish is a salmonoid fish. 
     
     
         6 . The composition for use according to  claim 1 , where the amoebic gill disease is caused by an infection of at least one of the amoebae  Paramoeba perurans  syn.  Neoaramoeba perurans  and  Paramoeba pemaquidensis , syn.  Neoparamoeba pemaquidensis.
