This study seeks to analyse the degree of infection of a euryhaline fish with the parasitic copepod Thersitina gasterostei in an extensive brackish‐water system. For this purpose, a survey of the occurrence of the parasite on three‐spined sticklebacks in the Norfolk Broads was conducted in Spring 1969. An attempt was made to correlate the incidence levels of T. gasterostei with variations in salinity. In addition, observations were made upon the location of the parasite on its host, the changes in maturation of the parasite during the sampling period and the differences in infection between three‐ and nine‐spined sticklebacks.
