Haematology and clinical blood chemistry in harbour porpoises ( Phocoena phocoena ) from the inner Danish waters
Harbour porpoises (Phocoena phocoena) in the Baltic Sea are under increasing pressure from anthropogenic activities, which affect the overall health of populations. Individuals’ haematologic and biochemistry parameters are known to be linked to a population's health status and are therefore use...

Harbour porpoises (Phocoena phocoena) in the Baltic Sea are under increasing pressure from anthropogenic activities, which affect the overall health of populations.
