Abstract

After 36% of hepatic mass removal , rainbow trout recovered its initial liver weight in 20-030 days, i.e., with a regeneration rate clearly lower than in mammals.During early regeneration process hematocrit index and hemoglobin content were slightly decreased, but both parameters rapidly reached their normal values.The evolution of both glycaemia and hepatic glycogen content supported the idea of the existence of a late regeneration wave, which, in this case, could begin at about the 20th post-operative day.
