The skin monogenean parasite, Entobdella hippoglossi Muller 1776 (family Capsalidae) has been found to commonly occur on broodstock halibut during the development of the culture of Atlantic halibut, Hippoglossus hippoglossus L., 1758. Due to the lack of information relating to its host’s ecology and recent establishment of the halibut farming industry, research on E. hippoglossi is lacking. This study, therefore, was carried out to investigate the biological and pathological aspects of E. hippoglossi, on the skin of Atlantic halibut under culture conditions.
A comparison of the parasite populations from two different sites, Machrihanish and Ardtoe, showed that the parasite burden from Machrihanish was twice that of the parasite population on Ardtoe halibut (641 ± 233.3 and 307 ± 276.6, respectively). The mean length of parasites, however, from the Ardtoe halibut was longer than those collected from the Machrihanish halibut (10.6 ± 3.3 mm and 6.0 ± 2.4 mm, respectively) (P
