The lizards were relocated to Thailand's Khaoson Wildlife Breeding Centre.
Villagers in Thailand's Samut Songkhram Amphawa district had a heap of trouble on their hands as Asian water monitors (Varanus salvator), a protected species in the country, set upon local fish farms, raiding the farms of the fish, according to a report in the Bangkok Post. In an effort to mitigate the losses and to reduce their numbers in the area, the government captured 641 of the lizards during a roundup this week. According to the report, the lizards raided fish from farms in 20 villages in the district and eight area townships.
The lizards were taken to the Khaoson Wildlife Breeding Centre in Ratchaburi's Chom Bung district and will be released.
