Gyrodactylidae ve Dacylogyridae (Monogeneanlar) ve Bunların Akuakültürdeki Önemi

Abstract

Monogeneans are parasitic worms, primarily on fishes, including, the Agnatha, the Chondrichthyes, and Osteichthyes. The monogenea includes at least two super-genera (.Dactylogyrus and Gyrodactylus) each of which has hundreds of species, possible reason for this include their high host specificity and short generation time. They are widespread throughout freshwater and marine habitats and about 4000 species have been described so far. Usually little or no harm is done to the host, but on occasion these flukes contribute to disease of the host in artificial system where fish are subject to number of stress factors. Besides being long recognized parasites, potentially severe pathogens have appeared, quite recently such as Gyrodactylus salaris which has destroyed salmon population in Norway. As more species of fishes became cultivable with the development of aquaculture, the chances of fish losses caused by monogeneans will increase.
