Charoen Pokphand Foods (CPF), a leading agribusiness in Thailand, has initiated a defamation lawsuit against Witoon Lianchamroon, head of the BIOTHAI Foundation, after he alleged that the company is responsible for an outbreak of the invasive blackchin tilapia in Thailand's waterways. This species has been detrimental to local ecosystems and the livelihoods of farmers, as it outcompetes native fish. The lawsuit, which seeks 200 million baht in damages, has been labeled a SLAPP (strategic lawsuit against public participation) aimed at intimidating critics. Observers argue that this legal action distracts from the urgent need to address the invasive species crisis. The case coincides with ongoing discussions in Thailand regarding new anti-SLAPP regulations intended to protect public interest statements. Farmers and environmental activists have rallied for accountability and compensation for those affected by the fish invasion, which threatens to spread further across the country.
