Extract

An increasing interest has been generated in the potential use of oral vaccines in the prevention of diseases of farmed fish (Ellis, 1985; Manning & Tatner, 1985). As part of an investigation of the fate of ingested antigenic material in fish we have in previous studies (Hart, Wrathmell & Harris, 1986 a, b) examined the ontogeny and morphology of GALT in the common dogfish at the light-microscopic level. GALT was shown to occupy three niches throughout the gut: as accumulations of leucocytes in the lamina propria and as individual cells in the lamina propria and epithelium.
