All fish stink. Some stink more than others. When it comes to salmon company Tassal, there is a growing band of critics who think the odour is getting worse.

Like its big Tasmanian predecessor Gunns, Tassal is an unusual company because it has an open share register but has been led by the same chairman and CEO for more than a decade. Chairman Allan McCallum lives in Victoria but has been a Tassal director since 2003 and chairman since 2005. Managing director Mark Ryan was a PwC restructuring expert who decided to make his career building Tassal, that is now capitalised at $710 million. He’s been CEO since 2003 and a director since 2005.
