The trade in marine ornamental fishes includes over 1800 species and is regarded as an introduction source for non-native fishes. Given this large pool of potential invaders, a targeted approach that evaluates risk for groups of fishes with demonstrated invasion history is both practical and feasible. In this way, proactive risk management frameworks can be used to identify risky species prior to introduction. Though the establishment of introduced marine ornamental species is uncommon, the invasion of Pterois volitans and P. miles in the western Atlantic Ocean has demonstrated the risks associated with the marine ornamental industry. These species, along with several other lionfishes, are regularly imported into the United States. We used the Aquatic Species Invasiveness Screening Kit to evaluate the risk of invasion for 14 species of traded lionfishes in the genera Pterois, Dendrochirus, and Parapterois for southeastern United States coastal waters of the Gulf of Mexico and Atlantic Ocean. The lionfish invasion is widely considered to be one of the worst marine invasions to date. Despite this, risk associated with the trade of lionfishes was estimated to be low, with notable exceptions. We identify Pterois russelii, Pterois lunulata, and Dendrochirus brachypterus as species with potentially elevated invasion risk. State and federal management agencies within the western Atlantic, Gulf of Mexico, and Caribbean should consider a detailed evaluation of these species to inform management action. This study is the one of the largest risk screening application of marine fishes to date and demonstrates the utility of prioritizing risk assessment of taxa found in pathways with related or otherwise similar species with previous invasion history.

海洋观赏鱼贸易包括1800多种，被视为非本地鱼类的引进来源。鉴于潜在的入侵者数量庞大，一种有针对性的方法来评估具有明确入侵历史的鱼类群体的风险既实用又可行。通过这种方式，可以在引入之前使用主动风险管理框架来识别风险物种。虽然建立引进海水观赏物种是少见，入侵蓑鮋属volitans和P.英里在西大西洋，已经证明了与海洋观赏业相关的风险。这些种类以及其他几种l鱼定期进口到美国。我们使用了水生生物入侵筛选工具包来评估美国东南沿海墨西哥湾和大西洋中Pterois，Dendrochirus和Parapterois属中14种贸易狮子鱼的入侵风险。ion鱼入侵被广泛认为是迄今为止最严重的海洋入侵之一。尽管如此，除显着例外外，与estimated鱼贸易有关的风险估计较低。我们确定蓑鮋属russelii，蓑鮋属lunulata，以及树突棘属（Bendrochirus brachypterus）作为具有潜在升高的入侵风险的物种。西大西洋，墨西哥湾和加勒比海地区的州和联邦管理机构应考虑对这些物种进行详细评估，以告知管理行动。这项研究是迄今为止最大的海水鱼类风险筛查应用之一，它证明了优先考虑在具有相关入侵史的相关或其他相似物种的途径中发现的分类单元的风险评估的实用性。
