Elevated temperature during rearing diminishes swimming and disturbs the metabolism of yellow perch larvae.

ABSTRACT: Temperate waters, such as the Great Lakes, are predicted to increase in temperature by 1°C every decade. Many poikilothermic fish thermoregulate behaviourally, moving to more suitable thermal environments. Embryos are incapable of locomotion and may be exposed to non-optimal temperatures during development. Previous work has suggested that temperature increases during embryogenesis can alter growth rates in fish. However, less is known of whether these early-life exposures to elevated temperatures can impart alterations to the phenotypic plasticity of performance traits, particularly in temperate species. We hypothesized that increased embryonic incubation temperature would diminish the larval performance of yellow perch (Perca flavescens), a critical cultural and ecological species of fis
