Three Chilean salmon farming companies have topped a list of the 20 most profitable Chilean shares in 2018.

The Chilean producer aims to raise the number of smolts it puts to sea by nearly one million a year.

The Chilean Service of Fisheries and Aquaculture (Sernapesca) has confiscated 200,000 tonnes of fishmeal - from Marfood, Fiordo Austral and Blumar - in the Biobio region, as part of an investigation carried out on processing plants in the area.

Blumar has been the first salmon producing company listed on the Santiago stock exchange to report Q3 results, showing losses in the period despite improved ex-cage costs.
