K. BUCHMANN Department of Hygiene and Microbiology, Royal Veterinary and Agricultural University, 13 Biilowsvej, DK-1870 Frederiksberg C., Denmark (Received 26 May 1989, Accepted4 July 1989) Key words: Pseudodactylogyrus; eels; infection level; host size In ecological studies of monogenean infestations of fish little attention has been paid to the importance of the host size. However, Frankland (1955) and Paperna et al. (1984) provided evidence of a positive correlation between host size and monogenean parasitization level, and the present paper reports on this subject in Anguilla anguilla infected by the gillparasitic monogeneans Pseudodactylogyrus spp. The study was conducted in the commercial eel-culture system described by Buchmann (1988~).On two occasions (experiments 1 and 2) small pigmented eels (total length 74-12.5 cm) parasitized only by adult parasites (prevalence 50%, abundance 1-1) were placed for 7 days in a fish tank with oncomiracidia present, after which 27 of the eels in each experiment were examined for post-larvae of Pseudodactylogyrus spp. as described by Buchmann (1988~). The relationships between body length of eels and number of postlarvae recorded on the gills is shown in Fig. I(a), (b). On a third occasion larger eels (total length 164-25.5 cm) infected only by adult parasites (prevalence 45%,
