Assessment of resistance to amoebic gill disease in the Tasmanian Atlantic salmon selective breeding population ...
The main priority in the breeding goal of the recently established Tasmanian Atlantic salmon selective breeding program is for resistance to amoebic gill disease (AGD), which is caused by the marine ectoparasite Neoparamoeba perurans and is characterised by hyperplastic changes to the gill tissue.
