Better tools for field studies

How can marine mammals under human care improve studies in the field?

Conserving and managing species in the wild requires the proper tools and data interpretation. Studies with our animals in the lab allow us to develop new technologies (FatMeter, QFASA) and properly interpret data collected from the field (diet determination, blood and hormone values, behaviour). We also assess possible impacts of field research on study animals (anesthesia effects, tag drag).
