          Abstract

          This paper provides the first report of the invasive Asian fish tapeworm, Bothriocephalus acheilognathi Yamaguti, 1934, in Honduras. The cestode was found in Profundulus portillorum (Cyprinodontiformes: Profundulidae), which represents a new host record, and which is a member of a genus faced with a variety of conservation challenges, now potentially complicated by the presence of this pathogenic cestode. Nearly complete sequence data from the ITS-1 5.8S and ITS-2 regions corroborate the determination based on morphological characteristics. Several species of carp were introduced to Honduras for aquaculture purposes in the early 1980s and the presence of the Asian fish tapeworm in Honduras may be related to these introductions. In addition, this report documents the currently known geographical distribution of this parasite in Central America, first recorded from Panamá and now from Honduras.

          Cet article présente la première mention du cestode de poissons invasif asiatique Bothriocephalus acheilognathi Yamaguti, 1934 au Honduras. Le cestode a été trouvé chez Profundulus portillorum (Cyprinodontiformes: Profundulidae), un nouvel hôte, qui est membre d’un genre auquel se posent de nombreux problèmes de conservation, désormais potentiellement compliqués par la présence de ce cestode pathogène. Les données des séquences presque complètes des régions ITS-1 5.8S et ITS-2 corroborent la détermination sur la base de caractéristiques morphologiques. Plusieurs espèces de carpes ont été introduites au Honduras à des fins d’aquaculture dans le début des années 1980 et la présence du cestode de poissons asiatique au Honduras pourrait être liée à ces introductions. En outre, cet article rapporte la répartition géographique actuelle connue de ce parasite en Amérique centrale, d’abord signalé au Panama et maintenant au Honduras.

          Helminth parasites of native Hawaiian freshwater fishes: an example of extreme ecological isolation.

           C Tate,  F Font (1994)
          The Hawaiian Islands harbor a depauperate native freshwater fish fauna comprised of 4 endemic gobies (Gobiidae) and 1 endemic sleeper (Eleotridae). We hypothesized that the natural helminth parasite community of these stream fishes would be depauperate because of colonizing constraints. In the absence of exotic fishes, native fishes in streams of Hanakapi'ai and Nu'alolo valleys harbored no adult helminth parasites. In Hakalau Stream on Hawai'i and Wainiha River on Kaua'i, we found introduced swordtails and guppies (Poeciliidae); here, the native gobioid fishes shared species of helminths with poeciliids. They were the nematode Camallanus cotti, the Asian tapeworm Bothriocephalus acheilognathi, and the leech Myzobdella lugubris. Such parasitological data should be incorporated into management plans for the conservation of native Hawaiian stream fishes as these parasites have been previously demonstrated to cause disease.

            Parasites in paradise: patterns of helminth distribution in hawaiian stream fishes

             Davinia Font (1998)
            Of the 13 species of helminths that parasitize stream fishes in Hawai'i, seven species are considered to be native to the archipelago and the remaining six species to be introduced by man. Sources of colonization for native species are piscivorous birds for three species, and marine fishes for four species. Non-native helminths have been brought to Hawai'i in association with the importation of parasitized exotic species of poeciliids introduced into streams for mosquito control and as aquarium releases. Many of these introduced parasites have broad host specificity and now infect the five species of native gobioid stream fishes. Exotic parasites, including a roundworm Camallanus cotti, a tapeworm Bothriocephalus acheilognathi and a leech Myzobdella lugubris, are more widely distributed among Hawaiian streams than are native species.

              Host specificity and population structure of two exotic helminths, Camallanus cotti (Nematoda) and Bothriocephalus acheilognathi (Cestoda), parasitizing exotic fishes in Waianu Stream, O'ahu, Hawai'i.

              Introduction of exotic fishes into Hawai'ian streams has resulted in the simultaneous introduction of exotic parasites. Camallanus corti (Nematoda) and Bothricephalus acheilognathi (Cestoda) are the most prevalent and abundant fish helminths in Hawai'ian streams. The population structure and host specificity of C. cotti and B. acheilognathi in exotic poeciliids were examined during May and June 1995 in Waianu Stream, O'ahu, Hawai'i. Prevalence and mean abundance of C. cotti were significantly different among Poecilia reticulata (65.2%, 1.05), Poecilia mexicana (49.0%, 0.87), and Xiphophorus helleri (32.3%, 0.44). Prevalence of B. acheilognathi was significantly higher in P. mexicana (6.1%) than in P. reticulata (2.1%) and X. helleri (1.6%). However, tapeworm differences in mean abundance were not significant among P. mexicana (0.08), P. reticulata (0.04), or X. helleri (0.03). Nematode and tapeworm prevalence and mean abundance were not significantly different with regard to fish sex. Camallanus cotti prevalence and mean abundance increased as P. mexicana body size increased (r2 = 0.84 and r2 = 0.72, respectively), whereas B. acheilognathi displayed no significant trend with respect to poeciliid body size.
