An ecological study of Cottus cognatus Richardson in Northern Saskatchewan

Abstract

The slimy sculpin, Cottus cognatus Richardson, is a widely distributed yet little known species of fish occurring in Northern Saskatchewan. This project was undertaken in an attempt to broaden our knowledge of its ecology and behavior. A wealth of other publications exist on various aspects of classification, distribution, ecology or behavior of particular species in the genus.

The nature of the investigation was primarily an exploratory field study. In addition certain supplementary laboratory investigations bearing on reproduction, feeding and fighting behaviour and tolerance to high temperatures were carried out.
