Rheological properties of rainbow trout blood

The effects of shear rate and red cell concentration on the viscosity of rainbow trout (Salmo gairdneri) blood were evaluated at 0 and 15 °C using a cone-plate viscometer. The viscosity of blood was shear dependent at both temperatures, with the highest values occurring at the lower temperature and...

Viscosity of blood increased in a linear fashion between hematocrits of 0 and 40%.
