Oslo-based Bluefront Equity has taken a 52 percent stake in Norwegian aquatech company Redox.

Averoy, Norway-based Redox was established in 2004 to develop new and environmentally friendly technologies for fish welfare and biosafety in aquaculture operations.

On its website, the company says it has traditionally worked with vessels, but in recent years it has also "moved ashore" to implement new uses for its technology.
