LSG can trace its operations to 1899 when fisherman-farmer Ole Mikkel Lerøen started selling live fish at the fish market in Bergen, Norway. Since 1999, LSG has acquired substantial interests in various domestic and international enterprises. Today LSG is the leading exporter of seafood from Norway, and distributes over 3 million seafood meals around the world every day.

LSG aims to be the leading supplier of sustainable, quality seafood.
