Abstract

In a factorial crossing experiment with individually reared lake trout Salvelinus numaycush eggs, genetic effects explained only a little of the total phenotypic variance in hatching time and alevin size, whereas environmental and maternal effects explained a much larger proportion of variation. Larger eggs produced larger hatchlings, but survival was independent of egg size. (C) 2002 The Fisheries Society of the British Isles.
