Blood viscosity in arctic fishes
Abstract The blood viscosity of arctic char, Salvelinus alpinus , and shorthorn sculpin, Myoxocephalus scorpius , from the arctic (74° 42′N) was measured with a cone‐plate viscometer. Blood viscosity of the two arctic species was considerably lower, less shear rate dependent, and less temperature de...

| Summary: | Abstract The blood viscosity of arctic char, Salvelinus alpinus , and shorthorn sculpin, Myoxocephalus scorpius , from the arctic (74° 42′N) was measured with a cone‐plate viscometer. Blood viscosity of the two arctic species was considerably lower, less shear rate dependent, and less temperature dependent than the blood of winter flounder ( Pseudopleuronectes americanus ) from more temperate waters. The rheological properties of the arctic fish blood would minimize blood flow resistance and thus be advantageous at the low temperatures (0°C) characterizing their environment. |
