Rating summary

Atlantic salmon are farmed in open net pens in the sea. Producing fish in open systems can cause environmental impacts. The GLOBALG.A.P. standard mitigates many areas of environmental concern, including discharge of effluents, use of chemicals, escapes, disease and parasite interactions. However, lethal control of predators is permitted. The GLOBALG.A.P. standard has criteria in place for welfare and humane slaughter. The GLOBALG.A.P. feed standard has criteria that requires reporting on the amount of responsibly sourced ingredients but no requirement for their percentage inclusion.  Due to the lack of data in relation to some of the environmental impacts of salmon farming, MCS is advocating a halt in industry expansion using existing practices until more evidence is available.This rating is based on full compliance with certification requirements. Commercial buyers should therefore ensure that full compliance has been achieved in order for this rating to be applicable. Rating last updated April 2023.
