The histopathology associated with the pre‐adult and adult stages of Lepeophtheirus salmonis on the Atlantic salmon, Salmo salar L.
Abstract. Atlantic salmon, Salmo salar L., infected with the pre‐adult and adult stages of Lepeophtheirus salmonis were obtained from sea loch cage sites on the west coast of Scotland, and infection experiments were carried out in the laboratory. The motile parasites were retained at the point of at...
