The anadromous sockeye salmon (Oncorhynchus nerka) spends at least its first year of life in lakes where it exists as a schooling pelagic species and feeds almost exclusively on entomostracan zooplankton. In this respect, BabiBe Lake and Nilkitkwa Lake (Fig. 1) are the principal nursery lakes for sockeye salmon of the Skeena River system in north central British Columbia. Initial survey study of the Babine Lake system was undertaken by the present author in 1955; and, in 1956, intensive studies of the ecology of young sockeye salmon during their period of lake residence were inaugurated and continued through 1963. An important part of these studies was quantitative study of the pelagic entomostracan zooplankton which was carried on throughout this period. The purpose of this report is to give a record of the station positions, to describe the methods of collection and analysis~ and to present the basic data for most of the samples taken. It is intended to be of use to investigators in future research on these lakes, as well as to be a source of the original data which is impossible to reproduce in its entirety in publications in the open literature,
