Tridge summary

Thailand has caught over 1.3 million kilograms of the invasive blackchin tilapia fish, found in 19 provinces, as it poses a threat to ecosystems and the fish-farming industry. Originally from West Africa, the fish were first discovered in Thailand in 2010 and have spread to the US and the Philippines. The Thai government has declared the eradication of the species a national priority, encouraging people to consume it and offering payment for catching it. Authorities are also releasing predator species to control the population and developing genetically modified tilapia to produce sterile offspring. The UN has warned about the rapid spread of alien species, causing significant damages and lost income.

Fishing authorities caught 1,332,000kg of blackchin tilapia from February to Wednesday last week, said Nattacha Boonchaiinsawat, vice president of a parliamentary committee set up to tackle the spread of the fish. “We talked to local residents and found out that the spread of tilapia has got worse — they found them in small canals, which was not the case before,” Nattacha said.
