Effects of seasonal variations in temperature and transport stressor on blood protein and glucose concentrations in wild teleosts of marbled sole(Limanda yokohamae) and greenling(Hexagrammos otakii)

The seasonal trends of plasma protein and glucose concentrations in marbled soles(Limanda yokohamae) and greenlings(Hexagrammos otakii), and the influence of transport stressor on those levels were investigated. Total plasma protein levels of marbled soles and greenlings in late spring and summer were significantly higher than those in winter(January). Plasma glucose levels were consistently increased according to elevation of water temperature both in marbled soles and greenlings. Transport stressor gave rise to decrease of plasma protein levels and increase of blood glucose levels.
