In conclusion, this first record of digenean trematode larvae in the gonad of Megapitaria squalida indicates that these bivalves serve as an intermediate host of the parasite and that high infection density causes parasitic castration, thereby affecting the reproduction of the host.
Parasitic castration is the partial or total inhibition of gametogenesis of a host species due to the activity or physical presence of a parasite (Cheng, 1983).
Models of brood mortality and parasitic castration in crustacean fisheries suggest that adaptive management strategies, such as intensive fishing of both sexes in heavily infected localities, may be able to break the threshold of nemertean transmission without reducing yield to the fishery (Kuris and Lafferty 1992).
The parasitic castration must have some benefit for the parasite, either more growth or success of transmission.
