. The cellular response of whiting, Merlangius merlangus (L.), to Contracaecum and Anisakis larvae parasitic in the liver was characterized by the presence of neutrophils, macrophages and proliferating fibroblasts. A capsule formed around the larvae after the removal of all necrotic debris by phagocytic cells. Melanin granules were deposited around the capsule. Four types of blood leucocytes were identified; thrombocytes, lymphocytes, monocytes and neutrophils. Phagocytic activity of the neutrophils and macrophages was suggested by the presence of dark stained bodies within them.
