Some Relations of Land Drainage, Nutrients, Particulate Material, and Fish Catch in Two Eastern Canadian Bays

Abstract

A year's record of the carbon content of living and of carbon and nitrogen content of nonliving suspended particulate material from St. Margaret's Bay, Nova Scotia, is presented. From considerations of carbon/nitrogen ratios and nutrient data from other sources, the nitrogen budget is briefly considered. The possible importance of land drainage into the bay leads to some positive correlations between runoff and catch of four commercially important species in the Gulf of St. Lawrence.
