Serum biochemistry and haematology in wild and captive bearded seals (Erignathus barbatus) from Svalbard, Norway
Background: Health assessment of seals in captivity include haematology and serum biochemistry measurements. Because such parameters differ between species, it is crucial to have species-specific reference values for the interpretation of clinical samples. Furthermore, differences in nutrition and e...
