Last month's latest attack on trucks carrying farmed salmon has once again brought the struggle for indigenous rights into sharp focus, and left the industry at a loss for how to approach the movement.

The Chilean salmon industry was collateral damage in a long-running conflict over indigenous land rights in Chile during a recent upsurge in violence in Chile's southern central La Araucania region.

The incident and others like it prompted strong condemnation from the Chile Salmon Council trade group whose members -- Chile-based AquaChile and Salmones Aysen, Norway's Mowi and Mitsubishi-owned Cermaq -- account for around half of the country's production.
