Host Response of Atlantic Salmon ( Salmo salar) to Infection by Sea Lice ( Caligus elongatus)
Atlantic salmon (Salmo salar), naturally infected with Caligus elongatus in seapen cages in Brandy Cove, St. Andrews, N.B., were examined histologically and ultrastructurally for signs of pathology associated with the attached chalimus larvae. Naturally -infected fish and fish that had never been ex...
