Co‐infection patterns of infectious salmon anaemia and sea lice in farmed Atlantic salmon, Salmo salar L., in southern Chile (2007–2009)
Abstract Infectious salmon anaemia virus ( ISAV ) caused a large epidemic in farmed A tlantic salmon in C hile in 2007–2009. Here, we assessed co‐infection patterns of ISAV and sea lice ( SL ) based on surveillance data collected by the fish health authority. ISAV status and SL counts in all Atlanti...
