Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Pearl Gourami (Trichopodus leerii) is a species of small freshwater fish native to Southeastern Asia, specifically the Malay Peninsula and the islands of Sumatra and Borneo. It is also considered native to Thailand but is most likely extirpated. It is a very popular fish in the ornamental trade and used as a food source in Malaysia. There is some captive breeding for the ornamental trade. The history of invasiveness is None Documented. There are records of introductions and some resulted in established wild populations. No information on ecological impacts was found. A single record of beneficial economic impact was found. The climate match is low. The entire contiguous United States had a low climate match. However, georeferenced observations were not available for established wild populations in two countries, contributing to uncertainty of the climate match. The certainty of assessment is low because both georeferenced locations and studies of impacts to native species were not found for established populations. The overall risk assessment is uncertain.
