Scientists are unsure what is causing the extremely low return rates and uncertainty surrounds the tracking and whereabouts of the rest of the fingerlings from recent years. But on Thursday November, 5 2009 Prime Minister Harper announced the start of a judicial inquiry to look at the declines.

The inquiry will be headed by B.C. Supreme Court Justice Bruce Cohen who will examine the cause of the collapse looking at everything from human error and fish farming standards, to environmental disaster. He will report back with recommendations by May 1 2011.
