Study shows black bears need a va­ri­ety of salmon species

The Western Star - - CANADA -

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.
