Study shows black bears need a variety of salmon species
VANCOUVER — A new study by Canadian researchers shows that black bears need different species of salmon rather than huge numbers of them in a short period to be healthy.
Lead author Christina Service says it is the equivalent of humans going to an all-you-caneat buffet for just a couple of days versus having one good meal a day for many months. The PhD candidate from the University of Victoria says if bears have access to a portfolio of different salmon species, then they have access to more and better food for a longer period of the year.
The team of researchers used chemical techniques on hair samples from black bears to estimate their salmon consumption, which showed population productivity and health.
