Intestinal helminth fauna of the shortfin mako Isurus oxyrinchus (Elasmobranchii: Lamnidae) in the northeast Atlantic Ocean.

Large oceanic sharks represent a suitable model to investigate the influence of a host's oceanic conditions on the structure of its helminth communities. In this study, we describe the intestinal helminth fauna, and investigate determinants of infracommunity structure, in 39 specimens of shortfin mako Isurus oxyrinchus collected in the NE Atlantic. Six cestode species were found in the spiral valve of makos: 3 are typical from lamnid sharks, namely, gravid specimens of Clistobothrium montaukensis, Gymnorhynchus isuri and Ceratobothrium xanthocephalum, and 3 are immature specimens of cestode species common to several elasmobranchs, namely, Dinobothrium septaria, Nybelinia lingualis, and Phyllobothrium cf. lactuca. In addition, L3 larvae of Anisakis sp. type I were detected. Infracommunities were species poor and had low total helminth abundance. The result of Schluter's variance ratio test was compatible with the hypothesis of independent colonization of helminth taxa. These results conform to previous studies on oceanic predators that have hypothesized that these hosts should have depauperate and unpredictable helminth infracommunities because oceanic conditions hamper parasite transmission. However, mean species richness and mean total abundance of cestodes of shortfin mako and other oceanic sharks did not significantly differ from those of elasmobranchs from other habitats. This suggests that the large body size and prey consumption rates of oceanic sharks offset the negative 'dilution' effect of oceanic habitat on transmission rates. Additionally, or alternatively, parasites of oceanic sharks may have expanded the use of intermediate hosts through the trophic web to spread out the risk of failure to complete their life cycles.

Notes on metazoan parasites of Alepisaurus ferox and Xiphias gladius of the eastern Arabian Sea

Documentation of fish parasites is important in describing the biodiversity of a given water body. In this study, the first record of metazoan parasite fauna of long snouted lancetfish (Alepisaurus ferox) and swordfish (Xiphias gladius) of the eastern Arabian Sea is presented. Three cestodes (Pelichnibothrium speciosum, Tentacularia coryphaenae and Hepatoxylon trichiuri) and one trematode (Botulus microporus) were collected from the lancetfish. Parasite prevalence was 98.04 % and the average intensity was 9.58. In the swordfish, all the samples were infected, and the average parasite intensity was 51.4. Five cestodes (Hepatoxylon trichiuri, Fistulicola plicatus, Nybelinia bisulcata, Nybelinia lingualis and Tentacularia coryphaenae), at least two species of nematodes (Hysterothylacium incurvum and unidentified nematodes), one species of copepode (Pennella instructa), and a trematode (Hirudinella ventricosa) were collected from the swordfish.

Endoparasites of <i>Trachurus picturatus</i> (Pisces: Carangidae) from the Madeira and Canary Islands: Selecting parasites for use as tags

In order to evaluate the use of parasites as biological tags to identify populations of the oceanic horse mackerel, Trachurus picturatus , two samples of 100 fish each, caught off the Madeira and Canary Islands from January to June 2009, were examined for the presence of anisakids, trypanorhynchs, acanthocephalans and liver coccidians. In T. picturatus from Madeira, prevalence of the coccidian Goussia cruciata reached 82%, whereas prevalence of the nematode Anisakis sp., the acanthocephalan Rhadinorhynchus cadenati and the trypanorhynch Nybelinia lingualis were 12.0%, 8.9% and 7.0%, respectively. In samples from the Canary Islands, prevalence of G. cruciata was 8.0%, Anisakis sp. and R. cadenati reached 5.0% and 42.0% respectively, and N. lingualis was not recovered. The absence of N. lingualis and the lower prevalence of Anisakis sp. appear to be related to the smaller size of the oceanic horse mackerels examined from the Canary Islands. Although significant differences in prevalence of two parasites, G. cruciata and R. cadenati , were found between the two regions investigated (χ 2 =125.13, df=1, p=0.000 and χ 2 =40.77, df=1, p=0.000), only G. cruciata was considered useful as a biological tag for the identification of populations of T. picturatus . In order to reach sound conclusions, an expansion of the temporal and spatial sampling strategy is recommended.

Helminth parasites of the oceanic horse mackerelTrachurus picturatusBowdich 1825 (Pisces: Carangidae) from Madeira Island, Atlantic Ocean, Portugal

The helminth parasite fauna of the oceanic horse mackerel Trachurus picturatus Bowdich 1825, caught off the Madeira Islands was composed of six different taxa. Prevalence and abundance of larval Anisakis sp. (Nematoda: Anisakidae) and Nybelinia lingualis (Trypanorhyncha: Tentaculariidae), the most common parasite taxa, were 24.3%, 0.9 and 37.9%, 0.7, respectively. Bolbosoma vasculosum (Acanthocephala: Polymorphidae) and the monogeneans Heteraxinoides atlanticus (Monogenea: Heteraxinidae) and Pseudaxine trachuri (Monogenea: Gastrocotylidae) were comparatively rare. The depauperate helminth fauna of the oceanic horse mackerel at Madeira compared to other geographical regions of the north-eastern Atlantic, namely the Azores banks and the West African coast, may be attributed to the paucity of nutrients off oceanic islands and to a low density of the fish population.

Aggregation patterns of macroendoparasites in phylogenetically related fish hosts

Macroparasites are generally aggregated within their hosts with infection and aggregation levels resulting from a continuous arms race between maintaining high mating probability and host mortality low for which host and environmentally related factors contribute to some extent. Here, infection and aggregation patterns of the macroendoparasites infecting the flatfish Citharus linguatula, Arnoglossus laterna, Lepidorhombus boscii, Scophthalmus rhombus and Platichthys flesus in 3 areas along the Portuguese coast were analysed. Of the 21 macroendoparasite species found only 1 infected all hosts and most were host or area exclusive. For each host-parasite system, values of the indices varied between areas and macroendoparasites were not always aggregated; in fact, some macroendoparasites were generally uniformly distributed, which can be related to specific density-dependent regulation mechanisms. No general pattern was found for infection or aggregation levels of the 3 species infecting more than 2 hosts along the Portuguese coast, i.e. Lecithochirium rufoviride, Nybelinia lingualis and Anisakis simplex s.l., suggesting that regulation mechanisms are not species specific but are locally determined, with host ecology playing a significant role.

A total of 36 specimens with lengths between 39.1 and 52.2 cm were sampled, which had taken 14 different prey items belonging to 4 major taxonomic groups (Chaetognatha, Crustacea, Mollusca and Teleostei). The most abundant prey organisms were Myctophidae and Euphausiacea, followed by Copepoda (Calanoida), Decapoda, Chaetognatha and Cephalopoda. Fishes were also the dominant prey in terms of biomass. Cannibalism was observed in 7 specimens of subadult L. caudatus. A total of 11 parasite species were identified in/on L. caudatus. We established 9 new host and 8 new locality records. Infestation rates were congruent with diet composition, indicating that parasites were ingested via mesopelagic prey organisms serving as intermediate hosts. The rich parasite fauna in L. caudatus reflects a high diversity of mesopelagic species at the GMS, providing niches for parasites and their intermediate hosts. While several species such as Paradiplectanotrema lepidopi (Monogenea) and Nybelinia lingualis (Cestoda) are typical parasites of L. caudatus, other species such as Sphyriocephalus tergestinus (Cestoda), Anisakis simplex (Nematoda) and Bolbosoma vasculosum (Acanthocephala) seem to be transferred by hosts migrating into the area, indicating an important role of the GMS in the transoceanic distribution patterns of such parasites.

Macroparasites of five species of ray (genus Raja) on the northwest coast of Spain

A parasitological study of rays captured on the Atlantic continental shelf off the estuary Muros-Noia in NW Spain (42 degrees 35' to 42 degrees 41' N, 9 degrees 2' to 9 degrees 10' W; mean capture depth 11.6 +/- 4.1 m) was performed. A total of 128 rays were examined: 52 specimens of Raja microocellata, 60 of R. brachyura, 6 of R. montagui, 3 of R. undulata and 7 of an unidentified Raja species, known locally as 'fancheca'. A total of 23 macroparasite species were detected: 5 monogeneans (Acanthocotyle sp., Calicotyle kroyeri, Empruthotrema raiae, Merizocotyle undulata, Rajonchocotyle emarginata), 11 cestodes (Acanthobothrium sp., Crossobothrium sp., Echeneibothrium sp., Echinobothrium brachysoma, Grillotia erinaceus, Grillotia sp., Lecanicephalum sp., Nybelinia lingualis, Onchobothrium uncinatum, Phyllobothrium lactuca, Tritaphros retzii), 6 nematodes (Anisakis simplex, Hysterothylacium sp., Histodytes microocellatus, Piscicapillaria freemani, Proleptus sp., Pseudanisakis baylisi) and a copepod (Holobomolochus sp.). All parasite species were present in several ray species, except for Acanthocotyle sp. and G. erinaceus (detected only in R. brachyura), H. microocellatus (detected only in R. microocellata) and T. retzii (detected only in R. montagui). Three species (C. kroyeri, M. undulata, E. brachysoma) have not been reported previously from Spain. The host with the highest parasite species richness was R. brachyura (18 species), followed by R. microocellata (17) and the unidentified Raja species (14). The parasite with the highest prevalence in R. microocellata was M. undulata, followed by R. emarginata, Acanthobothrium sp. and Echeneibothrium sp. The species with the highest prevalence in R. brachyura was R. emarginata, followed by C. kroyeri and P. baylisi. Some differences in parasite prevalence were detected between sexes and among size classes in both R. brachyura and R. microocellata.

Taxonomic reports of Homeacanthoidea (Eucestoda: Trypanorhyncha) in Lamnid and Sphyrnid elasmobranchs collected off the coast of Santa Catarina, Brazil

Elasmobranch specimens of lamnid and sphyrnid captured in 1999 in the State of Santa Catarina, Brazil, were parasitized with homeacanthoid trypanorhynch cestodes: Isurus oxyrinchus Rafinesque, 1810 with Nybelinia lingualis (Cuvier, 1817) Dollfus, 1929; Sphyrna zygaena (Linnaeus, 1758) with Heteronybelinia rougetcampanae (Dollfus, 1960) Palm, 1999. New details of internal morphology and/or scolex and/or proglottid surface ultrastructure are given. Adults of N. lingualis are reported for the first time in the Brazilian coast.

Larval trypanorhynchs (Platyhelminthes: Eucestoda: Trypanorhyncha) from black-scabbard fish, Aphanopus carbo and oceanic horse mackerel, Trachurus picturatus in Madeira (Portugal).

Four different types of trypanorhynch postlarvae were found attached to the stomach mucosa, external stomach wall or free in the body cavity of two marine fishes from Madeira, namely blackscabbard fish, Aphanopus carbo and oceanic horse mackerel, Trachurus picturatus. Morphological features shown by SEM indicated that the postlarvae belonged to the species Tentacularia coryphaenae, Sphyriocephalus tergestinus, Nybelinia lingualis and possibly N. yamaguitii. Prevalence [mean intensity (range)] of T. coryphaenae, S. tergestinus and Nybelinia spp. in A. carbo (n = 135) was 12.6% [1.65 +/- 1.27(1-6)], 5.9% [1.57 +/- 0.79 (1-3)] and 2.2% [1.33 +/- 0.58 (1-2)] respectively. The prevalence of T. coryphaenae and S. tergestinus showed some seasonality, with a rise in prevalence of T. coryphaenae corresponding to a decrease in prevalence of S. tergestinus. However these differences were not significant. In T. picturatus (n = 304) only N. lingualis was found at a prevalence of 9.6%. Both S. tergestinus and N. lingualis were recovered only from the stomach mucosa or external stomach wall, while T. coryphaenae was observed either attached to the stomach mucosa or free in the visceral cavity of the fish. The paper presents the first scanning electron micrographs (SEM) of Sphyriocephalus tergestinus and a new geographical record of N. lingualis in T. picturatus.

Prevalência e intensidade de infecção de cestóides Trypanorhyncha de elasmobrânquios nos estados do Paraná e Santa Catarina, Brasil

Twenty-nine specimes (32.2%) of elasmobranch fishes, out of 90 captured in the south coast of Brazil in the States of Parana and Santa Catarina, represented by six families, seven genera and nine species, were parasitized with cestodes of the order Trypanorhyncha: Heptranchias perlo and Squalus sp. parasitized with Progrillotia dollfusi; Isurus oxyrinchus with Nybelinia lingualis and Gymnorhynchus isuri; Prionace glauca with Tentacularia coryphaenae, Hepatoxylon trichiuri, Molicola horridus, Floriceps saccatus and Callitetrarhynchus gracilis; Carcharhinus signatus with Heteronybelinia yamagutii, H. nipponica and P. dollfusi; C. longimanus and C. obscurus with T. coryphaenae; Sphyrna zygaena with Heteronybelinia rougetcampanae and Callitetrarhynchus speciosus; Dipturus trachydermus with Mixonybelinia beveridgei. Prevalences and intensities of infection are presented as well as the analysis of the hosts sex-related parasitism, in single or concomitant infections. Data are discussed and compared with previous available reports on these hosts, mainly those referring to the species I. oxyrinchus, P. glauca and C. longimanus

Biotic relationships of Illex coindetii and Todaropsis eblanae (Cephalopoda, Ommastrephidae) in the Northeast Atlantic: Evidence from parasites

Abstract Parasites were collected from 1,200 short-finned squid (Illex coindetii, Todaropsis eblanae) caught as bycatch in a multispecies trawling fishery in the northwest Spanish Atlantic waters in 1992-1993. Parasites found included six species of helminths, threetetraphyllidean cestodes (Phyllobothrium sp., Pelichnibothrium speeiosum, Dinohothrium sp.), two trypanorhynchidean cestodes (Nybelinia yamagutii, Nybelinia lingualis), and one ascaridoid nematode (Anisakis simplex B). Two of these parasites (Phyllobothrium sp., A. simplex B), which could be recognised as component species, were used in analyses of host-parasite relationships. Levels of infection varied significantly with host size or stage of maturation for both squid species. Regional variation in infection level seems attributable to geographical variation in availability of prey, discreteness and movements of host populations and to size or age-related changes in the prey selection oftheir host. Parasite evidences suggest that both ommastre...

Study on the cestodes in Theragra chalcrogamma

This study was performed to investigate the intestinal parasites (especially cestoda) in the guts of Theragra chalcogramma in Korea. The cestode larvae collected were morphologically observed and measured, and at the same time, microscopical study was done with the section slides of the cestode larvae. They were identified on the basis of the descriptions by Schmidt and Yamaguti. The results obtained in this study are as follows: The cestode larvae were identified as Khawia sinesis, Eulacistorhynchus chiloscyllius, Tentacularia coryphaenea, Pseudonybelinia odontacantha and Nybelinia lingualis. These are new species reported in Korea. The characteristics of Khawia sinesis are its scolex lacking loculi and broad, flat and fimbriate shape. Its neck is not separated from the body but a little constricted. Eulacistorhynchus chiloscyllius is characterized by fairly long and acraspedote scolex. The bulbs are long; retractor muscles are attached to bases of the bulbs. The two bothridia are oval or round in shape and lacking posterior notch. The tentacles are long and poeciloacanthus; double chainette present. Tentacularia coryphaenea is characterized by its long craspedote and subcylindrical scolex. The bothridia are separated, without free borders and spinous. The tentacles are short, slender, armed with solid hooks in spirals, similar except the base of tentacle. The tentacle sheaths are not twisted. The bulbs are ellipsoidal. Pseudonybelinia odontacantha is characterized by its craspedote scolex. The tentacles are inserted near anterior margin of bothridia and armed with hooks in spirals ascending left to right. The hooks are similar, throughout tentacle, with feeble curve and provided with a tooth-like protuberance on the ventral side. The bulbs are three times longer than its width. The posterior margins of bothridia have a pair of eversible ciliated pits; or fossettes. Nybelinia lingualis is characterized by its short and craspedote scolex. The bothridia are separated, with free boarders. The tentacles are cylindrical, armed with solid and similar hooks in quincunxes.
