Hobart-based salmon farmer Tassal announced on Friday that three directors on its board had resigned in a group departure the company's chairman acknowledges as somewhat unusual.
Tassal chairman Allan McCallum said in a statement to the Australian Securities Exchange that David Groves, Gary Helou and Clive Hooke had quit Tassal's seven-person board.
Mr McCallum thanked each of the directors for their contributions to Tassal and wished them well.
Including the latest resignations, four directors have quit the Tassal board in the past six months.
Jill Monk resigned as a director in late October 2011 after eight years on the Tassal board.
Mr Helou and Mr Hooke had been directors of Tassal since November 2010.
Mr Groves had been on the Tassal board since February 2007.
Mr McCallum told AAP the three directors had quit for "a range of personal issues".
"They vary," he said.
Mr McCallum later said that on Thursday the board had decided to appoint a director with financial experience and expertise.
"He's going through a due diligence process, and we're set to announce that on Wednesday after he's finished that."
Speaking to AAP on Friday, Mr McCallum acknowledged that it seemed odd that three directors would quit at once.
"I accept that" he said.
"Once we put this further announcement out of Wednesday it might become clearer, but up until then that's about as far as I wish to go at this point."
Tassal booked a profit for the first half of the 2011/12 financial year of $12.96 million, down from $14 million in the prior corresponding period.
Shares in Tassal were 0.5 cents lower at $1.31 on Friday.
