Abstract The peritoneal exudates of seabream and sea bass consist of granulocytes, lymphocytes and macrophages. These cells show conspicuous ultrastructural differences from the same cell-types of blood and head-kidney, which have not been reported previously. Peritoneal exudate granulocytes differ from their corresponding circulating or head-kidney forms in the following way: (a) they are larger in size, and (b) their abundant cytoplasmic granules have some new ultrastructural features, and a new granule population might also be present. Likewise, lymphocytes also show a noticeable difference; they contain a sparse population of small dense cytoplasmic granules. Monocytes, macrophages, and transitional forms between these two cell-types, are also found. The percentage of peritoneal exudate cell-types is different in seabream and sea bass. Macrophages in sea bass represent the most abundant peritoneal exudate cell-type. However, seabream shows lower percentages of macrophages than granulocytes.
