The General Department of Customs in Vietnam is taking action to protect the environment and agricultural production by cracking down on the import of crayfish. Recent reports of smuggled crayfish products in the Vietnamese market have prompted the department to request local customs officials to increase control and inspection measures. The department has referred to laws and decrees that prohibit the import of invasive alien species, including crayfish (Procambarus clarki). This species is not allowed to be traded in Vietnam, as it is on a list of alien species that pose a risk of invasion.
