“…It is, therefore, surprising to note that these parasites can withstand the muscular activity in the intestine of the host and are not voided along with the faeces. F. plicatus is the specialist parasite for X. gladius (Garcia et al 2010) and as documented in this study, has shown high prevalence and intensity in the swordfish from the Atlantic Ocean (Hogans and Hurley 1986;Garcia et al 2010). Similar to the findings in the present study, Hogans and Hurley (1986) had documented the variations in the morphology of scoleces of F. plicatus collected from the northwest Atlantic Ocean.…”

“…The swordfish (Xiphias gladius Linnaeus, 1758) and long snouted lancetfish (Alepisaurus ferox Lowe, 1833) are two important large pelagic predators inhabiting the tropical, temperate, and sometimes cold waters of the world oceans (Froese and Pauly 2011). Parasite fauna of these fishes is fairly well documented in the Atlantic and the Pacific Oceans (Monticelli 1889 ;Nigrelli 1938;Yamaguti 1959;Gibson and Bray 1977;Hogans et al 1983;Scholz et al 1998;Castro-Pampillon et al 2002;Garcia et al 2010). However, the metazoan parasites of these predators in the Indian Ocean are poorly studied.…”

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.

Infection levels and diversity of anisakid nematodes in blackspot seabream, Pagellus bogaraveo, from Portuguese waters

et al. 2011

The blackspot seabream, Pagellus bogaraveo, is a sparid fish of great economic importance in the northeast Atlantic. The main aim of this work was to assess the infection levels and diversity of anisakid nematodes parasitizing P. bogaraveo from Portuguese waters. The anisakid larvae were identified by polymerase chain reaction-restriction fragment length polymorphism analysis and ten different patterns were observed, four of which were not previously reported in the literature. Moreover, several species were detected for the first time in this host: Anisakis simplex × Anisakis pegreffii hybrids, Anisakis ziphidarum, Anisakis typica, Anisakis physeteris, as well as three undescribed anisakids Anisakis sp. PB-2009, Anisakis sp. PB-2010, and Contracaecum sp. PB-2010. The ITS1-5.8S-ITS2 region was sequenced and analyzed phylogenetically, revealing that our anisakids were distributed by the two distinct clades reported previously, corresponding to the two recognized larval morphotypes. Moreover, a group of organisms, including our specimens from Madeira and the previously reported Anisakis sp. HC-2005, cluster together and seem to belong to clade I. A certain degree of intraspecific diversity was also detected. Samples from mainland waters had the highest infection levels and were dominated by A. pegreffii. Madeira had the highest diversity overall, dominated by Anisakis sp. PB-2010. Fish from the Azores had the lowest infection levels, and the species with the highest relative abundance was A. physeteris. The anisakid nematode communities were relatively similar in mainland waters but very distinct in both the Azores and Madeira islands, suggesting the existence of at least three different stocks of P. bogaraveo in the northeast Atlantic.

“…Such use of Ansakis spp. as biological indicator for host fish stocks identification have been used particularly for Atlantic horse mackerel [21,15,16], Jack mackerel (Trachurus symmetricus murphyi) [102], European hake (Merluccius merluccius) [14,15], swordfish (Xiphias gladius) [15,20], and herring (Clupea harengus) [18]. Other metazoan parasites, apart from Anisakis, have also been reported as possible use to distinguish fish stocks of rough scad (Trachurus lathami) [19] and herring [18].…”

Journal of Coastal Zone Management AbstractCheap protein sources from fishery products come from both capture fishery and aquaculture industries. Despite the available technologies that help increase wild catch and aquaculture production, our food security is being threatened by several factors including parasitic infections. Zoonotic parasites infecting our fishery products are one of the several concerns for our food safety. Among these include the infections with the nematode Anisakis in marine fishes and cephalopods causing human anisakiasis and/or allergy-associated health risks, the nematode Gnathostoma causing gnathostomiasis, and food poisoning due to the myxozoan infection of the genus Kudoa. On the other hand, the increasing human population, dwindling fish catch from the wild, degradation of aquatic environment, and declining or slow growth of aquaculture sector due to parasitic diseases are all posing global threats to the security and sustainability of fish supplies. The wild fish populations are affected by the parasitic diseases that directly and indirectly affect fish reproduction, growth, and survival, whereas intensifications of aquaculture operations cause fish health problems associated to parasitic diseases resulting to decline in production. Despite these negative impacts of parasites, there are several parasite groups that are used as biological indicators for food chain structure, heavy metal contamination, environmental pollutions and fish stock assessment (i.e., nematodes Anisakis, Hysterothylacium, Anguillicola, Spirophilometra, Raphidascaris, and Philometra; acanthocephalans Pomphorhynchus, Serrasentis, and Acanthocephalus; cestodes Bothriocephalus, Monobothrium, and Ligula; monogenean Pseudorhabdosynochus; and digenean Didymodiclinus), as well as reducer of heavy metal accumulation in the body of their host fish (i.e., acanthocephalans Pomphorhynchus and Acanthocephalus). The use of these parasites for proper management of fishery resources can be of help in addressing food safety, fish security, and food sustainability, while at the same time managing our fishery resources. As we are addressing these global issues, these parasites that we are considering as threats can be of useful value to attain sustainable development.
