Of 128 burbot, Lota lota, collected from the Ford River in August 1983, 1984, November 1984, and May 1985, 121 were infected with at least one of the following parasites: Azygia sp., Crepidostomum farionis, Posthodiplostomum sp., Cystidicoloides tenuissima, Haplonema hamulatum, Raphidascaris acus, N...

Description
Summary:Of 128 burbot, Lota lota, collected from the Ford River in August 1983, 1984, November 1984, and May 1985, 121 were infected with at least one of the following parasites: Azygia sp., Crepidostomum farionis, Posthodiplostomum sp., Cystidicoloides tenuissima, Haplonema hamulatum, Raphidascaris acus, Neoechinorhynchus pungitius, Neoechinorhynchus saginatus, Myzobdella lugubris, Elliptis sp., Epistylis sp., Myxobolus sp., and Trichodina sp. Of the helminths found, R. acus and H. hamulatum had the highest prevalence and mean intensity, respectively. The prevalence of Myxobolus sp. decreased with burbot age. The prevalence of Epistylis sp. and Elliptis sp. and the prevalence and mean intensity of H. hamulatum and R. acus increased with burbot age. Taxonomically, the helminth fauna consisted of 263 (24%) trematodes, 741 (67%) nematodes, and 96 (9%) acanthocephalans. Using Brillouin's index, the mean diversity value ± 1 SD of counted helminths in infected burbot was 0.302 ± 0.333; the mean evenness was 0.303 ± 0.295.
