Etude préliminaire du phytoplancton du lac Saint-Louis, élargissement du fleuve Saint-Laurent près de Montréal, Québec

Abstract

Seventeen samples were collected at regular intervals from September 1970 to December 1971 from four sites on lake St. Louis; these stations received their water either from the St. Lawrence River, the Ottawa River, or both. For each species and sample of the 178 phytoplankton entities found, the number of cells per liter was estimated. A general view of the distribution of plankton organisms at each station is given as well as the seasonal variation of the major systematic groups and the dominant species.
