WWF has drafted new standards for tilapia farming to address the environmental impacts associated with the scaling up of the industry. The first draft of the standards for responsible tilapia aquaculture were released last week as a result of the WWF-initiated Aquaculture Dialogues. Increasing demand for tilapia in developed countries had led to many Asian producers switching from small-scale operations to larger, export-driven enterprises that had thrown up major environmental concerns, WWF argued.

The standards aim to reduce reduce some of the negative environmental impacts of aquaculture such as chemicals and waste contaminating waters and escaping fish having a harmful effect on the marine ecosystem. Although currently only farmed in small quantities in the UK, the fish is thought to have major growth potential here.
