Mowi's $1.3 million (€1 million) settlement to get rid of a class action lawsuit alleging misleading marketing seems like a relatively tidy way to make a pesky lawsuit disappear.

But take a step back, and the salmon farming giant may have inadvertently opened up the floodgates for similar suits, not just against its own products but those of the broader seafood industry -- wild and farmed -- as well.

A million-dollar fine is small change for Mowi, the world's most valuable seafood company.
