Mechanisms underlying thermally induced growth plasticity in juvenile Pacific halibut.

ABSTRACT: Growth plasticity in aquatic ectothermic vertebrates is an important factor driving somatic growth variation in natural populations in response to environmental change. In fish, growth plasticity is primarily due to changes in skeletal muscle growth, as this tissue is a major component of the body mass, with water temperature being a primary abiotic factor affecting growth. Investigating skeletal muscle growth plasticity is therefore key for understanding somatic growth variation. The Pacific halibut (Hippoglossus stenolepis) is an important fish species in the North Pacific Ocean ecosystem that has experienced marked changes in size-at-age over the last 100 years. Here, we investigated the molecular basis of growth plasticity in juvenile Pacific halibut acclimated to different temperature
