US land-based salmon producer AquaBounty is casting doubt on its own future as it calls on shareholders to approve a "reverse stock split" of the company's common stock in a bid to boost the share price and minimize the risk of being delisted from the Nasdaq Capital Market.

A potential delisting would materially adversely affect AquaBounty's ability to raise capital or pursue strategic restructuring, refinancing or other transactions on acceptable terms, or at all, the company warned in a stock filing.
