The vast majority of farmed salmon on the market is Atlantic salmon raised in net pens in the ocean, these are raised in both Pacific and Atlantic waters. A small number of operators also grow Chinook in net pens.
Many of the environmental concerns with farmed salmon stem from the use of net pens where farmed fish, waste, and chemicals or antibiotics used are in direct contact with the marine ecosystem. The need for salmon to eat more wild fish in their feed than can be produced as farmed fish is an additional concern because of the drain on global fisheries resources.
Update September 2013: SeaChoice currently only refers to the worldwide science assessment of open net-pen farmed salmon, which states that all regions are ranked red and receive an avoid recommendation. SeaChoice does not acknowledge the individual producer report for “Verlasso” farmed Atlantic salmon. SeaChoice applies the precautionary principle to individual producer assessments. Therefore, as open-net pen salmon farming exhibits inherent variability to a number of environmental factors (such as disease outbreaks, escapes, antibiotic/chemical reliance, etc), obtaining a sufficient time-series data set that includes full production cycle data over a number of cycles is crucial in determining accurate statistical trends in order to provide full data confidence.
