Assessing body fat percentage of grizzly bear

Field personnel use bioelectrical impedance to assess body fat percentage of captured bears.  The procedure is similar to how body fat is measured in humans and is based on the resistance of body tissues to the flow of a small, harmless electrical signal.  The electrical current is impeded more by fat tissues compared with tissues that are composed mostly of water, thus
