UBC scientists want to see if orcas’ dinner plate is empty or full -Vancouver Sun


More research coming on chinook and their relationship to Orcas.

UBC researchers will track chinook salmon as they navigate the summer feeding grounds of the southern resident killer whales, to see if the whales’ dinner plate is empty or full. About 100 mature wild chinook are being fitted with high-tech acoustic tags near Port Renfrew on the west coast of Vancouver Island to see how they behave in the presence of the salmon-eating orcas, and hopefully determine why the whales appear malnourished. Is there a shortage of chinook — their preferred food — or is noise from freighters and oil tankers interfering with the whales’ ability to catch enough fish to feed themselves? Randy Shore reports.
