Camallanus cotti (Nematoda: Camallanidae), an introduced parasite of fishes in New Caledonia

Abstract

Abstract.A pathogenic Asian nematode species of Camallanus, C. cotti Fujita, 1927, was found in New Caledonia, South Pacific, for the first time; it was recorded from two native fishes, Awaous guamensis (Valenciennes) (Gobiidae) (prevalence 51%, intensity 1-25) and Kuhlia marginata (Cuvier) (Kuhliidae) (a single specimen found

Rhabdochona (Rhabdochona) keralaensis sp. nov. (Rhabdochonidae) and some other nematodes in the Indian mottled eel Anguilla bengalensis bengalensis from India

“…Site Comments: The general morphology and measurements of nematodes of the present material are in agreement with those of C. cotti, as redescribed, e.g., by Yamaguti (1941), Moravec and Sey (1988), Moravec and Nagasawa (1989), Rigby et al (1997) and Moravec and Justine (2006) and, consequently, it is apparent that they belong to this species. Camallanus cotti was originally described by Fujita (1927a, b) from fishes of Lakes Biwa and Tazawa in Japan; later it was redescribed based on specimens collected from different Japanese fishes by Yamaguti (1935Yamaguti ( , 1941 and Moravec and Nagasawa (1989).…”

“…Species of cyprinids are the most frequent fish hosts of C. cotti (see Justine 2006, Wu et al 2007). According to Moravec and Justine (2006), C. cotti seems to be originally distributed in eastern, south-eastern and southern Asia, from where it has been recorded from Japan, China, eastern Russia (Amur River basin), Korea, Vietnam, Singapore and India. It also occurs in the cultures of aquarium fishes in Europe, North America (Canada), South America (Brazil), West Indies (Puerto Rico) and Australia, where this pathogenic parasite is being brought in along with exotic fishes, imported mainly from Singapore (e.g., Schubert 1972, Stump 1975, Campana-Rouget et al 1976, Levsen 2001, Menezes et al 2006.…”

It has also been reported from native and introduced fishes in some streams in Hawaii and New Caledonia, where it was apparently brought in along with the introduction of some fishes, mainly poeciliids (e.g., Font and Tate 1994, Font 2003, Moravec and Justine 2006.…”

New data on the morphology of Procamallanus (Procamallanus) annulatus and Procamallanus (Spirocamallanus) monotaxis (Nematoda: Camallanidae) from marine fishes off New Caledonia

“…It is remarkable that the tail tip of first-stage larvae of P. annulatus from uterus is provided with several digit-like processes. Similar caudal processes in first-stage larvae have hitherto been reported only for two species of the camallanid genus Camallanus Railliet et Henry 1915 (see Moravec and Justine, 2006) and recently also for the African species P. laeviconchus (Wedl, 1862) (Mašová et al, 2010). It has been mentioned above that P. annulatus was previously reported from off Indonesia and Sri Lanka (Yamaguti, 1955;Parukhin, 1971Parukhin, , 1976 (Machida & Taki, 1985;Moravec et al, 2004).…”

“…from Epinephelus cyanopodus (Richardson). Two other species of camallanids, Camallanus cotti Fujita, 1927 and Procamallanus (Procamallanus) pacificus Moravec, Justine, Würtz, Taraschewski et Sasal, 2006 were reported from New Caledonian freshwater fishes (Moravec & Justine, 2006;Moravec et al, 2006b). Parasitological examinations of marine fishes off the coast of New Caledonia yielded, among other helminths, two intestinal camallanid species of Procamallanus Baylis, 1923 parasitizing the golden-lined spinefoot Siganus lineatus (Valenciennes) (Siganidae), the longspine emperor Lethrinus genivittatus Valenciennes and the slender emperor Lethrinus variegatus Valenciennes (both Lethrinidae), that were not previously reported from this region.…”
