The nutritive ecology of Lac la Plonge and Canoe Lake
… state to another in the food chain. The physico-chemical features of a lake are important to the extent that they control the supply of nutrients and influence the rate of circulation of food material within the lake. It was felt that the study of the nutritive ecology of Lac la Plonge and Canoe …
