Spatial and temporal distributions of larval sealworm (Pseudoterranova decipiens, Nematoda: Anisakinae), inHippoglossoides platessoides (Pleuronectidae) in eastern Canada from 1980 to 1990

Molecular studies on larvae of Pseudoterranova parasite of Trichiurus lepturus Linnaeus, 1758 and Pomatomus saltatrix (Linnaeus, 1766) off Brazilian waters

“…The oceanic habitat of the definitive hosts may probably influence the prevalence of parasitism, reducing the chances of infection in the coastal regions. Similar conclusions have been shown by McClelland et al (2000) that found significant differences comparing infection of larvae of P. decipiens in Gadus morhua from Canada where the populations of cod inhabiting areas near breeding sites of seals had infection levels significantly higher. This is the first attempt to identify genetically the larvae of Pseudoterranova sp.…”

Use of parasite tags in delineating stocks of white hake (Urophycis tenuis) from the southern Gulf of St. Lawrence and Cape Breton Shelf

“…Given the frequency of stomach eversion in specimens obtained from deep water and the fact that analyses of parasite prevalences and abundances in 2001 samples indicated that useful marker species were lacking among parasites from stomachs and pyloric caecae, the latter organs were not inspected in hake sampled in 2002 and 2003. Fillets were removed and sliced into thin sections (McClelland et al, 2000) for detection of nematodes. Smears of the gall and swim bladders were stained with Giemsa's and examined under high dry magnification for the presence of micro parasites.…”

Use of parasites as tags in delineating stocks of Atlantic cod (Gadus morhua) from the southern Gulf of St. Lawrence and the Cape Breton Shelf

“…A dissecting microscope was used to examine gills and viscera for protozoan and metazoan parasites. The skeletal musculature was removed and sliced into thin sections for detection of nematodes and other parasites, free or encapsulated in the flesh (McClelland et al, 2000).…”
