Why we should be worried about 'Frankenfish' in south-east Asia

Unlike GM salmon, hybrid grouper gets little attention but they potentially pose a greater threat to marine ecosystems 

The fast-growing super salmon produced by American biotech company Aquabounty Technologies are poised to become the first genetically modified animals to hit food markets in the US, with approval from authorities widely expected later this year. But AquAdvantage® salmonhas made headlines because of the potential risks to wild stocks in the Atlantic should they escape and breed.

Hybrid grouper, on the other hand, gets almost no media attention, yet they potentially pose a greater threat to marine ecosystems because they’re farmed at sea, not inland like salmon. Hybridisation through in-vitro fertilisation is big in south east Asia, where aquaculture businesses are interbreeding valuable grouper species in a bid to create a fast-growing super fish.

Live grouper and other reef predators are highly-prized food in Hong Kong, Mainland China, Taiwan and other parts of south-east Asia. They crowd tanks in seafood restaurants and are ubiquitous at Chinese wedding banquets and other formal occasions, where tradition demands they are served. Grouper can sell for well over US$100 (£59) a kilo, with very large or rare specimens selling for much more.
