Hematology of free-ranging, lactating northern fur seals, Callorhinus ursinus.

Abstract

Thirteen standard hematology values were determined for a healthy and growing population of free-ranging, lactating northern fur seals (Callorhinus ursinus) from Lovushki Island in the Kuril Islands of far-east Russia. Results are presented from 24 females sampled between June and August during the 3-yr period of 2006-08. Hematologic values have been made available for future comparisons with the declining population of northern fur seals on the Pribilof Islands, Alaska, and are compared with published values for other otariid species.
