Summary
Biochemical reference intervals for harp seals (Phoca groenlandica) vary by age and whether the animal was sampled live or postmortem. These factors are crucial for accurate health assessments in wild and captive populations.
Area of Science:
- Marine Mammal Health
- Wildlife Physiology
- Ecosystem Health
Background:
- Harp seals (Phoca groenlandica) are key predators in the Northeastern Atlantic.
- Establishing biochemical reference intervals is vital for assessing harp seal health in captivity and wild populations facing environmental changes.
Purpose of the Study:
- To determine serum biochemical reference values for wild adult harp seals.
- Utilize current, readily available methods for biochemical analysis.
Main Methods:
- Collected blood samples from adult female harp seals and pups in the Greenland Sea.
- Analyzed serum electrolytes, substrates, end products, and proteins using a Technicon Axon analyzer.
- Compared results between live-sampled and postmortem-sampled seals, and between adults and pups.
Main Results:
- Serum glucose and triglycerides were lower, while urea was higher in postmortem-sampled seals compared to live-sampled seals.
- Seven of seventeen serum parameters differed significantly between adult harp seals and pups.
- Separate reference intervals were established for adult seals and seal pups.
Conclusions:
- Sampling method (live vs. postmortem) impacts serum biochemical values.
- Age significantly influences serum biochemical parameters in harp seals.
- Consideration of both sampling method and age is essential for accurate health evaluations in harp seals.
