Chemotherapy of fish parasites

Zeitschrift Für Parasitenkunde (Berlin, Germany), 1989
There are few agents on the market that control fish parasites. These are substances that are mainly used in other hosts; due to the different metabolism of fish, they often have only moderate effects on fish parasites. Therefore, the research and development of fish-specific antiparasitic compounds is needed to avoid the high losses suffered by ...

Parasites in cultured and feral fish

Veterinary Parasitology, 1999
Parasites, causing little apparent damage in feral fish populations, may become causative agents of diseases of great importance in farmed fish, leading to pathological changes, decrease of fitness or reduction of the market value of fish. Despite considerable progress in fish parasitology in the last decades, major gaps still exist in the knowledge of

Fish immunity to scuticociliate parasites

Developmental & Comparative Immunology, 2013
Some species of scuticociliates (Ciliophora) behave as facultative parasites and produce severe mortalities in cultured fish. Pathogenic scuticociliates can cause surface lesions and can also penetrate inside the body, where they feed on tissue and proliferate in the blood and most internal organs, killing the host in a few days.

Overdispersion In Marine Fish Parasites

Journal of Parasitology, 2012
A modification of Taylor's Power law was used to compare the degree of overdispersion in frequency distributions from 38 datasets of marine parasites, data that had originally been collected for fish stock discrimination. The results strongly indicate that the overriding factor contributing to overdispersion in these helminths and crustaceans is the ...

Reprint of “Fish immunity to scuticociliate parasites”
