Acidification has led to the extirpation of many fish populations from lakes in Europe and North America (Sevaldrud et al. 1980; Kelso et al. 1990; Berquist 1991). Numerous lakes around Sudbury, Ontario, Canada, have been acidified by the atmospheric

Temperature-sensing ultrasonic transmitters were used to monitor the behavior of eight individual lake trout Salvelinus namaycush in two lakes: a shallow lake that becomes isothermal (15–20°C) during late summer and a typical dimictic lake with a

Models of potential brood predators placed near the nest were used to elicit defence behaviour in male smallmouth bass (Micropterus dolomieui) in the field. The three predator models represented a conspecific, a species found in the lake (yellow perc

A matched-planting experiment was conducted to determine the most suitable salmonid genotype for stocking in former lake trout lakes that currently are too acidic to support lake trout reproduction. Hatchery-reared lake trout Salvelinus namaycush, br

We assessed redd characteristics of brook trout in a lake and a stream and alevin emergence in the lake. Both populations spawned over upwelling groundwater. In the lake site fish deposited eggs 7–19 cm in the sediment in an egg pocket that contain

We measured survival of caged overwintering young-of-the-year and introduced, free-swimming adult smallmouth bass Micropterus dolomieui in five Ontario lakes that varied in pH from 4.9 to 5.9 (winter values). No hatchery-reared young survived in lake

Year-class strength in northern populations of smallmouth bass is strongly influenced by winter starvation of young-of-the-year. We examined starvation among young bass under both winter and summer light and temperature conditions. During starvation,
