EPIDEMIOLOGY AND CONTROL OF PSEUDODACTYLOGYRUS INFECTIONS IN INTENSIVE EEL CULTURE SYSTEMS - RECENT TRENDS

The research efforts conducted to elucidate the epidemiology of Pseudodactylogyrus infections in the European eel Anguilla anguilla are described. Subjects as temperature dependent reproduction of gill monogeneans, biotic factors influencing the infection level, the microhabitats of the congeneric parasites, the relation between host size and parasite load and the development of host responses to infection are considered. In addition the investigations performed in the laboratory and in the eel farm in order to develop an effective anthelmintic treatment for control of Pseudodactylogyrus infections are presented.
