KEYS to NEMATODA

The following keys are designed to aid identification of larval and/or adult nematodes recovered from Canadian fishes from any aquatic environment, be it fresh water, brackish water or marine. The keys may be unsuitable for identifying material from other areas.

A single asterisk (*) preceding a nematode’s scientific name denotes that the taxon has been recorded only in its larval stage in given fish host(s), a double asterisk (**) denotes records of both larvae and adults in given host(s), whilst an unadorned taxon denotes records of only adults in given host(s).
