Distribution and structure of lesions in the gills of Atlantic salmon, Salmo salar L., affected with amoebic gill disease
Gills of Atlantic salmon, Salmo salar L., with amoebic gill disease (AGD), were analysed by routine histology to identify lesion morphology and distribution patterns. Numbers of lesions occurring dorsally, medially and ventrally in the gill filaments were recorded as was lesion size, proximity to th...
