Sample Notes
; Most evident on a few of the fish were large black spot trematode metacercaria. It appeared some of the fish were clearing these (host tissue rejecting the parasite). Several fish had large Ligula plerocercoids in body cavities. 1 Fish had a Diplostomum in eye. Several fish had Myxidium sp in gall bladders and 1 fish had Chloromyxum in gall bladder. There was a lack of intestinal parasites probably because of capture and holding (possible purging of systems). Several fish had very small trematode metacercaria in mesentery, 1 fish had Posthodiplostomum minimum in mesentery. ; ; Disease Signs: A few of the fish had very large black cysts evident in tissue.
