Cymothoa borbonica prevalence in the buccal cavity of Trachinotus botla was high, with 45 % of all fish sampled being infected. Smaller fish were more susceptible to infection with no parasites found in fish over 400 mm FL. The detrimental effects of parasite infection on their hosts include basihyal (the bone commonly known as the “tongue”) damage, a loss in buccal cavity volume as a result of female parasite attachment, and a severe impact on host growth. By combining short-term dietary… 
Parasitic Isopod Cymothoa eremita (Brünnich 1783) (Isopoda: Cymothoidae) Affects the Growth of Black Pomfret Parastromateus niger (Bloch 1795) in the Southeast Coast of India
The diet composition examination was a small indication to suggest a change in either feeding habits or diet of fish where parasitized and non-parasitized fish occupied the similar tropic niche, and due to an infestation of C. eremita in P. niger, the relative condition factor was found to be lower than that of the uninfested fish.
Cymothoa indica Schioedte and Meinert, 1884 (Crustacea: Isopoda: Cymothoidae) infestation in cage-cultured Asian seabass Lates calcarifer (Bloch, 1790) from the south-west coast of India
Infestation of the isopod parasite Cymothoa indica  in Asian seabass Lates calcarifer (Bloch, 1790) fingerlings stocked in low volume cages in Ashtamudi Lake, Kerala, south-west India is reported here.

It is found that the isopod can stay over three years in the buccal cavity of yellowback sea-bream and that isopods parasitized smaller than those examined and grew steadily as their hosts grew.
Effects of the parasitic isopod Ichthyoxenus japonensis Richardson, 1913 (Isopoda, Cymothoidae) on the growth and gonad development of the goldfish Carassius auratus Linnaeus, 1758
The results suggest that the reproductive ability of the host was severely reduced by infection of the isopod, but that the gonads of the castrated fish could recover after the loss of theIsopods.
Understanding growth relationships of African cymothoid fish parasitic isopods using specimens from museum and field collections
The status of Florida pompano, Trachinotus carolinus , as a commercially ready species for U.S. marine aquaculture
Owing to their high value, in the 1950s researchers and commercial ventures began investigating the potential of Florida pompano, Trachinotus carolinus , for aquaculture; however, initial efforts did
Indo-West Pacific species of Trachinotus with spots on their sides as adults, with description of a new species endemic to the Marquesas Islands (Teleostei: Carangidae).
A new species, Trachinotus macrospilus, is described from the Marquesas Islands where it is endemic and the only species of the genus present.
Evolutionary History of Crustaceans as Parasites
This chapter summarizes the modern aspects, evolutionary history and fossil record of parasitic crustacean groups with emphasis on their fossil record to improve the understanding of parasitism in general.
The Ecological Significance of Parasitic Crustaceans
This chapter should demonstrate to readers that there are still far more questions than answers about the role of parasitic Crustacea in aquatic systems, but based on what the authors know today, they can say they are likely one of the most critical players in aquatic ecosystem dynamics.
Host-dependent differences in resource use associated with Anilocra spp. parasitism in two coral reef fishes, as revealed by stable carbon and nitrogen isotope analyses
This is the first study to use stable carbon and nitrogen isotope analyses to examine differences in resource use by Caribbean coral reef fishes associated with parasitism and to evaluate how closely related parasites might have host-dependent effects on host trophic ecology.


Livoneca sp. (Flabellifera: Cymothoidae), an isopod parasite in the oral and branchial cavities of the Red Sea silverside Atherinomorus lacunosus (Perciformes, Atherinidae)
This host-parasite relationship appears to be species-specific and has all the characteristics of an evolutionary process of adaptive strategy, as it clearly enables the host to maintain its feeding ability while the parasite grows to sexual maturity.
Occurrence and effect of the parasitic isopod, Lironeca ovalis (Isopoda: Cymothoidae), on young-of-the-year bluefish, Pomatomus saltatrix (Pisces: Pomatomidae).
The physiological cost associated with infection appears to be small and probably does not constitute a serious threat to individual bluefish survival, and the host-parasite relationship between P. saltatrix and L. ovalis is still unclear.
Elthusa alvaradoensis Rocha-Ramírez, Chávez-López & Bruce, 2005 (Isopoda, Cymothoidae) parasitizing the inshore lizardfish, Synodus foetens (Linnaeus, 1766) on the continental shelf off central Veracruz, Mexico
The prevalence, fecundity, and size distribution of the isopod, Elthusa alvaradoensis, parasitizing the inshore lizardfish, Synodus foetens on the continental shelf off central Veracruz, Mexico, were studied and male parasites exhibit a positive allometric growth, while this is negative for females.
Results indicate that Glossobius hemiramphi is a protandric hermaphrodite with an annual life cycle, and it cannot exclude the possibility that infested fish have a higher mortality rate than uninfested fish, at least temporarily.
Host-parasite relationships: occurrence and effect of the parasitic isopod Mothocya epimerica on sand smelt Atherina boyeri in the Mesolongi and Etolikon Lagoons (W. Greece).
The physiological cost resulting from this infection seems to be little and probably does not constitute a serious threat for individual host survival, and infections did not have a significant effect on the host's body condition, such as length-weight relationship, gonadosomatic index, hepatosomatic index and relative condition factor.
Cymothoid isopod parasites in aquaculture: a review and case study of a Turkish sea bass (Dicentrarchus labrax) and sea bream (Sparus auratus) farm.
The first case of infection by a cymothoid isopod (Ceratothoa oestroides) in Turkish aquaculture is reported, and its effects on sea bass Dicentrarchus labrax are analyzed.
Cymothoa hermani sp. nov. (Isopoda, Cymothoidae, Crustacea), a parasitic isopod, collected off the Zanzibar coast, Tanzania from the mouth of a parrotfish (Scaridae)
Cymothoa hermani sp. nov., a buccal fish-parasitic isopod is described from off Unguja Island, Zanzibar, from the buccal cavity of the marbled parrotfish, Leptoscarus vaigiensis. Cymothoa hermani sp.
Studies on the ichthyo‐fauna in Plover Cove Reservoir, Hong Kong: feeding and food relations
The food spectra of various fish species were analysed and compared and the results indicated that S. mossambicus played an important role in the ecology of this reservoir since all major food sources were exploited.
