A total of 1509 specimens of flounder Platichthys flesus (L.) were sampled in the period from April 1998 to March 2000 from the Gulf of Gdańsk. The seasonal occurrence of all parasite species was calculated. The results indicated that some parasite species occur seasonally (Diplostomum sp., Raphidascaris acus, Dichelyne minutus, Echinorhynchus gadi and Pomphorhynchus laevis), while others do not (Trichodina borealis, Hysterothylacium aduncum, Cucullanus heterochrous). Since some parasites occurred year-round at low levels of infection, it was difficult to determine if they exhibited seasonality or not (Glugea anomala, Gyrodactylus unicopula, Diplostomum mergi, Bothriocephalus scorpii and Lampetra sp.). Gyrodactylus flesi was noted occasionally.

Flounder Platichthys flesus (L.) (1509 specimens) was sampled randomly between April 1998 and March 2000 in the Gulf of Gdańsk. The sex, age, and parasites were determined. The prevalence, intensity, mean intensity, and relative density of the infection of the detected parasites were calculated according to host sex and age. Susceptibility to infection was related to host age. Each parasite species had its own host sex preferences. The results indicated that host age and sex could play a major role in the determination of parasitic infection in flounder.
