Forty-seven taxa of zooplankton were identified from collections taken during larval fish tows in the Tuktoyaktuk region. The zooplankton fauna consists of three components: a small number of common species characteristic of brackish water and a large number of rare species of either freshwater or marine affinities. Eurytemora gracilicauda Akatova l949, E. raboti Richard 1897, and E. richingsi Heron &Damkaer 1976 are newly recorded from Canada.
