Labels are meant to advertise products that go well beyond the legal minimum standard with regard to the conditions of manufacture, for example in terms of fair wages for suppliers, sustainability or animal welfare. The Aquaculture Stewardship Council (ASC)
was founded in 2010 with significant support by the WWF in order to promote "responsible fish farming" by establishing its own label.
However, the responsibility only covered the origin of the fish feed, a ban on genetic alterations in the animals, moderate use of antibiotics and compliance with minimum requirements regarding water quality. Criteria concerning handling and transport or killing of the animals were not taken into account. Information on the adverse effects of fish farming on animal welfare, the ecological consequences and the petition submitted at the end of 2017 can be found here
In its statement, the ASC announced that it would "define scientifically based and species-specific criteria regarding fish welfare", which could later be "coupled with ASC farm standards as an optional module". This is a first big and welcome step in the right direction, even if TIR would prefer to see mandatory standards introduced.
