MARGOLIS, L., AND J. R. ARTHUR. 1979. Synopsis of the parasites of fishes of Canada. Bull. Fish. Res. Board Can. 199: 269 p. Published information on the parasites of Canadian fishes is assembled in two lists, Parasite- Host and Host—Parasite. Eight hundred and thirty named species of the following taxa have been reported: Protozoa (77 species), Myxosporida (92), Turbellaria (1), Monogenea (163), Trematoda (179), Cestoidea (93), Nematoda (58), Acanthocephala (26), Hirudinoidea (21), Mollusca (3), Branchiura (10), Copepoda (104), and Isopoda (3). Additionally there are many records of parasites not identified 10 species level, including two species of Acarina. The Parasite—Host list is organized on a taxonomic basis and identifies for each parasite species its habitat (freshwater, marine, or brackish), site of occurrence (location) within the host, species of host(s), known geographic distribution in Canadian waters, and the published source of each host and locality record. The Host—Parasite list is organized according to taxonomy of the hosts and is accompanied by data on known distribution of the parasites. In addition to listing the cited references, a supplementary list of references is included to cover other Canadian literature on fish parasites. The work concludes with an index to parasites and hosts. Although taxonomie revision is not the aim of the synopsis, notes on taxonomy and nomenclature are included when appropriate and, of necessity, several new combinations and one new synonym are proposed. They are Prosorhyn- choides basargini (Layman, 1930) n.comb. for Bucephalopsis b.; Prosorhynchoides ozakii (Nagaty, 1937) n.comb. for Bucephalopsis o.; Prosorhynchoides pusilla (Stafford, 1904) n.comb. for Bucepha- lopsis p.,.

Résumé

MARGOLIS, L., AND J. R. ARTHUR. 1979. Synopsis of the parasites of fishes of Canada. Bull. Fish. Res. Board Can. 199: 269 p. Les auteurs assemblent en deux listes, une des parasites—hôtes et l'autre, des hôtes—parasites, les renseignements publiés sur les parasites des poissons canadiens. On y donne 830 espèces nommées, appartenant aux taxa suivants: Protozoa (77 espèces), Myxosporida (92), Turbellaria (1), Monogenea (163), Trematoda (179), Cestoidea (93), Nematoda (58), Acanthocephala (26), Hirudinoidea (21), Mollusca (3), Branchiura (10), Copepoda (104) et Isopoda (3). On y rapporte aussi plusieurs signalements de parasites non identifiés au niveau de l'espèce, dont deux Acarina. La liste des parasites—hôtes est structurée sur base taxonomique et, pour chaque espèce parasite, indique l'habitat (eau douce, eau salée, eau saumâtre), la site d'occurrence (position) au sein de l'hôte, la ou les espèces d'hôtes, la répartition géographique connue dans les eaux canadiennes et la source imprimée pour chaque donnée de localité de chaque hôte. La liste des hôtes—parasites est ordonnée suivant la taxonomie des hôtes et accompagnée de données sur la répartition connue des parasites. En plus d'établir la liste des références citées, on donne une liste supplémentaire de la documentation canadienne sur les parasites des poissons. L'ouvrage se termine par un index des parasites et des hôtes. Bien que ce synopsis nt vise pas à une révision taxonomique, il inclut des notes sur la taxonomie et une nomenclature quand la chose semble appropriée, et a dû proposer plusieurs nouvelles combinaisons et un nouveau synonyme. Ce sont : Prosorhynchoides basargini (Layman, 1930) n.comb. pour Bucephalopsis b.; Prosorhynchoides ozakii (Nagaty, 1937) n.comb. pour Bucephalopsis o.; Prosorhynchoides pusilla (Stafford, 1904) n.comb. pour Bucepha- lopsis p.; Thynnascaris brachyura (Ward et Magath, 1917 sensu Van Cleave et Mueller, 1934) n.comb. pour Contracaecum brachyurum; Thynnascaris magna (Smedley, 1934) n.comb. pour Contracaecum mg.; Thynnascaris melanogrammi (Smedley, 1934) n.comb. pour Contracaecum ml.; et Echinorhynchus ekbaumi Golvan, 1969, nouveau synonyme de E. gadi Zoega dans O.
