“…Indeed, the last authors have found that a significant sub-structuring was reported between mtDNA cox2 sequences data sets of the western and eastern populations of A. pegreffii of the Pacific Ocean, obtained from sequences deposited in Genbank, with respect to population of the same species collected by those authors from the Adriatic Sea. On the contrary, the same authors (Blažeković, et al, 2015) did not report significant genetic sub-structuring between Adriatic Sea and other Mediterranean populations of A. pegreffii; this last finding seems to be congruent with the low level of genetic differentiation here estimated at the SSRs level, between the populations of the Adriatic and Tyrrhenian Sea waters. The finding of a genetic substructuring of A. pegreffii from Austral and Boreal regions suggests that geographic distance would restrict the gene flow between "antipodean" populations of this parasite species.…”

The species of Anisakis constitute one of the most widespread groups of ascaridoid nematodes in the marine ecosystem. Three closely related taxa are recognised in the A. simplex (s. l.) complex, i.e. A. pegreffii, A. simplex (s. s.) and A. berlandi. They are distributed in populations of their intermediate/paratenic (fish and squids) and definitive (cetaceans) hosts. A panel of seven microsatellite loci (Anisl 05784, Anisl 08059, Anisl 00875, Anisl 07132, Anisl 00314, Anisl 10535 and Anisl 00185), were developed and validated on a total of N = 943 specimens of A. pegreffii and A. simplex (s. s.), collected in fish and cetacean hosts from allopatric areas within the range of distribution of these parasite species. In addition, the locus Anisl 7, previously detected in those Anisakis spp., was investigated. The parasites were first identified by sequence analysis of the EF1 α-1 nDNA. The panel of the microsatellites loci here developed have allowed to: (i) detect diagnostic microsatellite loci between the two species; (ii) identify specimens of the two species A. pegreffii, A. simplex (s. s.) in a multi-marker nuclear genotyping approach; (iii) discover two sex-linked loci in both Anisakis species and (iv) estimate levels of genetic differentiation at both the inter- and intra-specific level.

“…Since then, new collections with genetically identified worms have originated from teleosts already stated in Kuhn et al (2013) (Anshary et al 2014, Bak et al 2014, Mladineo & Poljak 2014, Chen & Shih 2015, Cipriani et al 2015, or from mammalian definitive hosts (i.e. Shamsi 2014, Blažeković et al 2015. With 53 Anisakis-hosting fish species presented in this study, about one-quarter of the worldwide known Anisakis fish host species and one-third of the worldwide hosts of genetically identified Anisakis genotypes have been reported from Indonesia, even though this country is comparatively understudied, considering its high biodiversity.…”

“…simplex larvae from all three fishing grounds shared the same (most abundant) haplotype. The generally low nucleotide diversity (0.007) was slightly lower in comparison with nematode larvae isolated from sardines from the California current (0.018) [ 29 ], the same as in Adriatic fish populations (0.007) [ 70 ], and higher than in cetacean hosts in the Adriatic population (0.0045) [ 71 ]. High haplotype and low nucleotide diversity stems mainly from single nucleotide mutations.…”

Parasites as Biological Tags for Stock Discrimination of Beaked Redfish (Sebastes mentella): Parasite Infra-Communities vs. Limited Resolution of Cytochrome Markers

et al. 2016

View full text Add to dashboard Cite

The use of parasites as biological tags for discrimination of fish stocks has become a commonly used approach in fisheries management. Metazoan parasite community analysis and anisakid nematode population genetics based on a mitochondrial cytochrome marker were applied in order to assess the usefulness of the two parasitological methods for stock discrimination of beaked redfish Sebastes mentella of three fishing grounds in the North East Atlantic. Multivariate, model-based approaches demonstrated that the metazoan parasite fauna of beaked redfish from East Greenland differed from Tampen, northern North Sea, and Bear Island, Barents Sea. A joint model (latent variable model) was used to estimate the effects of covariates on parasite species and identified four parasite species as main source of differences among fishing grounds; namely Chondracanthus nodosus, Anisakis simplex s.s., Hysterothylacium aduncum, and Bothriocephalus scorpii. Due to its high abundance and differences between fishing grounds, Anisakis simplex s.s. was considered as a major biological tag for host stock differentiation. Whilst the sole examination of Anisakis simplex s.s. on a population genetic level is only of limited use, anisakid nematodes (in particular, A. simplex s.s.) can serve as biological tags on a parasite community level. This study confirmed the use of multivariate analyses as a tool to evaluate parasite infra-communities and to identify parasite species that might serve as biological tags. The present study suggests that S. mentella in the northern North Sea and Barents Sea is not sub-structured.
