"This strategic alliance to sell Chilean salmon in the United States and Canada, seeks to achieve sales volumes big enough to supply salmon to the big retail and food service chains, which you can only sell to with significant salmon volume levels," said Blumar in a statement.

Under the agreement, Ventisqueros will take a 50 percent stake in Blumar's U.S.-based merchandising unit. The transaction is expected to be completed in October.

The terms of the agreement were not disclosed.

Chile is the world's second-largest salmon producer.
