The spatial distribution of yellow perch (Perca flavescens), white sucker (Catostomus commersoni), smelt (Osmerus mordax), chub spp. (Coregonus spp.) and alewife (Alosa pseudoharengus) caught in gill nets fished in South Bay of Lake Huron is described. The vertical distribution was essentially the same for all catches examined, the fish being concentrated towards the bottom of the net. The lateral distribution varied with species, mesh size and setting. Three types of lateral distribution were recognized, namely random, dispersed and bunched. Possible reasons for these different types and the relation between the distribution of fish in the net and in the water are discussed.
