Some Copepod and Isopod Parasites of Bermuda Marine Fishes
Journal of Aquatic Animal Health, 1994Abstract Three species are added to the depauperate parasite fauna of Bermuda: Caligus balistae, Lernanthropus talipes, and Alcirona insularis. The latter, normally a rare associate, seems to thrive on groupers (Serranidae) in captivity. An offshore record for Nerocila lanceolata on ocean triggerfish Canthidermis sufflamen contrasts with its known ...

Parasitic isopods associated with sea turtles nesting in Brazil
Journal of the Marine Biological Association of the United Kingdom, 2014Studies of sea turtle epibiosis have focused on the diversity and ecology of facultative commensalisms and less attention has been given to parasitic associations, in which the epibiont species derives nutrients from the tissue of the host turtle. We present the first description and quantitative survey of the parasitic isopodsExcorallana costata ...

Flabelliferan isopods (Crustacea) parasitic on freshwater fishes of Thailand
Systematic Parasitology, 1992Two species of flabelliferan isopods are described based on specimens found in the gill cavities and/or body surfaces of 13 species of Thai inland fishes. They are: Alitropus typus Milne-Edwards, 1840 (Aegidae) from Belodontichthys dinema, Cirrhinus jullieni, Cyclocheilichthys enoplos, Cynoglossus microplepis, Hampala macrolepidota, Kryptopterus ...

Host preference of an obligate fish parasitic isopod, Mothocya parvostis
Parasitology InternationalThe ability to recognize and successfully infest an appropriate host during its early life is under strong natural selection in parasitic organisms, as it directly affects the parasite's fitness. Although many cymothoid isopods that parasitize fishes exhibit high host specificity at the species level, it remains unclear whether the manca (i.e ...

Effects of River Hydrology and Physicochemistry on Anchovy Abundance and Cymothoid Isopod Parasitism
Journal of Parasitology, 2019The flow regime of a river is an important driver of many ecosystem components. However, few studies explore how differences in flow rates and water chemistry can influence communities of parasites and their hosts. Here, we investigate the impact of dissolved oxygen, pH, salinity, water temperature, and river flow on the abundance and prevalence of ...

Ecology of parasitic and micropredatory isopods on coral reefs [PDF]
Arthropod parasites and micropredators, such as ticks and mosquitoes, influence terrestrial ecosystems and harm their hosts directly and indirectly by vectoring micro-organisms. Whether micropredators similarly affect marine ecosystems and hosts is not well understood.

Veterinary Parasitology
The infestation of crustacean parasites affects the freshwater and marine fishes, causing retarded growth rate, reduced production, low reproduction, and mass mortality. Fish parasites from the isopod family Aegidae, in recent years, have received increased global attention due to their serious socio-economic, ecological, and welfare consequences in ...

Finding a balance: Reproductive trade-offs in parasitic isopods of the family Cymothoidae
Parasitology ResearchIn this study conducted along the coast of Odisha, India, reproductive trade-offs in isopods of the family Cymothoidae were investigated, focusing on the relationship between the number vs. volume of eggs and the percentage of brood to body volume. Ovigerous females from species with substantial sample sizes (n > 30) were analyzed to understand their ...

Invertebrate Systematics
Species in the parasitic isopod family Cabiropidae are known to utilise various isopods as hosts but there are currently no records of members parasitising anthuroid hosts. We describe Anthuroniscusgen. nov. for three new cabiropid species, Anthuroniscus shimomuraisp. nov., Anthuroniscus dentatussp. nov. and Anthuroniscus latussp.

A remarkable occurrence of isopod parasitism on an armoured catfish, Microlepidogaster maculipinnis
Journal of Fish Biology, 1993Numerous specimens of the armoured catfish species, Microlepidogaster maculipinnis collected in 1979 from four sites in Paraguay, were found to be parasitized by two species of cymothoid isopods, Artystone minima and Nerocila armata. The small size differential between isopods and host catfish, high incidence of infestation, pathology and details on ...
