The Chile Salmon Council, representing more half of the South American nation's salmon production, is calling for dialogue to create the conditions in which to build sustainable economic and social progress in the sector.

This comes after Sunday's referendum that saw Chile's electorate convincingly reject a new constitution that would for the first time have embedded rights of indigenous groups into law.

In recent years, the salmon farming industry has become unwittingly ensnared in the fight for indigenous land rights, suffering sporadic attacks on installations and vehicles transporting fish.
