What strategies has Thailand implemented to control the invasive fish species?

Question

Accepted Answer

Thailand has used public campaigns, predator releases, and genetically modified sterile fish to control the invasive blackchin tilapia
Thailand has implemented multiple strategies to control the invasive blackchin tilapia as it spreads through its waterways and affects 17 provinces. The government has encouraged public participation in fish-catching campaigns, introduced natural predators such as Asian seabass and long-whiskered catfish, and is developing genetically modified sterile blackchin tilapia for release by the end of the year. A parliamentary investigation is also underway to determine the cause of the outbreak and identify those responsible.
Public-led fish-catching campaigns to help remove the tilapia
One control approach involves encouraging public participation in fish-catching campaigns aimed at reducing the number of blackchin tilapia in local waterways. This strategy is part of the broader set of measures the government has put in place to combat continued spread.
Natural predator releases including Asian seabass and long-whiskered catfish
Authorities have also introduced the blackchin tilapia’s natural predators to control its population. Reported examples include Asian seabass and long-whiskered catfish, which are intended to prey on the invasive fish in affected areas.
Genetically modified sterile tilapia planned for release by year-end
In addition to predator-based controls, Thailand is developing genetically modified sterile blackchin tilapia to curb population growth. The plan is to release these sterile fish by the end of the year to reduce breeding and limit the tilapia’s ability to multiply.
Parliamentary investigation to determine how the outbreak started
Alongside these efforts, a parliamentary investigation is being conducted to determine the cause of the outbreak and identify those responsible for the spread. The origin remains unclear, with the government suspecting a laboratory experiment involving Charoen Pokphand Food (CPF), which has denied involvement and threatened legal action.
