Treatment

* Contracaecum osculatum (Rudolphi, 1802) Baylis, 1920 (sensu lato)

Includes: * C. osculatum A auct.; * C. osculatum B auct.; and * C. osculatum C auct.

Description (after J. W. Smith & Wootten 1984c, and Moravec 2013). NB: the following description applies also to

* Phocascaris sp. and/or * Contracaecum sp. (see below). Greenish brown in colour, sometimes tinged with red, L3

about 7 to 30 long, lying coiled in capsules of irregular shape ( J. W. Smith & Wootten 1984c). Mouth, lips, boring

tooth, and excretory pore similar to those of Anisakis simplex L3 (see Fig. 73 View FIGURE 73 A,B,C).

According to Moravec (2013), L3 are 3.81–22.00 long, maximum width 0.15–0.53. Oesophagus 0.55–1.71 long,

ventricular appendix 0.54–1.58, and intestinal caecum 0.20–0.89. Single excretory cell extends posteriorly to mid-

body region. Tail 0.09–0.21 long, narrows rapidly to a point lacking a mucron. Anterior and posterior ends of an L3

shown diagrammatically in Fig. 75 View FIGURE 75 A,B.

Sites: intestinal lumen, mesenteries, musculature, viscera

Hosts: Boreogadus saida (13); Gadus macrocephalus (11); Gadus morhua (1, 4, 5, 7, 8, 9, 10, 14, 16); Glyptocephalus cynoglossus (1); Hippoglossoides platessoides (10); Hippoglossus hippoglossus (11); Mallotus villosus (10); Myoxocephalus scorpius (10); Oncorhynchus mykiss (6); Oncorhynchus tshawytscha (12); Pseudopleuronectes americanus (10); Theragra chalcogramma (11); Urophycis tenuis (5, 15); unspecified “fish” (2, 3)

Distribution: Atlantic, Nunavut, Pacific
