VANCOUVER — Black bears need access to different species of salmon rather than huge numbers of a single variety in order to be healthy, a new study by Canadian researchers indicates.
Lead author Christina Service said if bears have access to a “portfolio of different salmon species,” then the animals have access to more food for a greater part of the year.
“It is the equivalent of humans going to an all-you-can-eat buffet for just a couple of days versus having one good meal a day for many months,” said the PhD candidate from the University of Victoria, adding that different species of the fish have different run timings and use different habitat.
