    Notes: Abstract. An outbreak of Dermocystidium infection in cultured eels, Anguilla anguilla L., from Scotland is described. The disease appeared in the winter months but did not cause significant mortalities or adversely affect the growth of the eels. Infected eels had large, elongate white cysts on the gills. The cysts consisted of a homogeneous layer of parasite origin surrounded by a fibrous capsule and hyper-plastic epithelium. Within the cysts were small spherical parasite cells with a densely staining central area and peripheral granular, vacuolated cytoplasm. The cell wall appeared to be broken down in many cases and the cells appeared degenerate. The cysts eventually collapsed and the cavity was filled with epidermal tissue.

    Notes: Abstract The parasite fauna of juvenile Atlantic salmon,Salmo salar L., at a smolt-rearing unit in eastern Scotland was monitored from two weeks after first-feeding until smolting occurred (May 1973–April 1975). A total of 625 fish was examined. Wild salmon from the river supplying the unit with unfiltered water were also examined. The cultured fish yielded eight protozoan and seven metazoan parasite species, all derived from wild fish. The parasite fauna of cultured fish became established quickly, subsequent changes involving loss of some species and increasing abundance of others. The metazoan parasite fauna was restricted to those species with free-swimming infective stages capable of entering the tanks.
