ABSTRACT: The African grey bichir Polypterus senegalus is a popular ornamental fish in Indonesia. Pet trade with this species is increasing, and aquaculture production is well established. Here we present a detailed market survey and volume of domestic trade, export and import between January 2018 and February 2021. Climate similarity between the native range of P. senegalus and Indonesia was analysed by the MaxEnt algorithm. A significant number of areas of numerous Indonesian islands were identified as suitable for survival and establishment of this fish. This was confirmed by the records of 3 likely established populations in rivers in Java and Sumatra, where both wild type and albino juveniles were captured. The occurrence of more feral populations was suggested by local fishermen in Kalimantan, Java, and Lombok islands; however, verification via future field trips is required. The culture of P. senegalus is unregulated in Indonesia, and the potential risk of establishment of this predatory fish and its potential spread in this Southeast Asian country is alarming for wildlife managers. Although a total ban seems the best solution, an alternative risk mitigation strategy with minimal negative effects on the socio-economic situation in local communities is more feasible. The albino phenotype of P. senegalus is probably less of a risk because of its easier detection by predators, higher sensitivity to disease and stress, and disrupted social behaviour. Since albinos are popular in Indonesia, replacing the wild phenotype with this potentially less invasive phenotype could be a recommendation after experimental confirmation of the lower invasiveness of albinos.

印度尼西亚塞内加卢蛉的养殖、贸易和建立，首次记录到野生种群

摘要： 非洲灰比奇鱼Polypterus senegalus是印度尼西亚流行的观赏鱼。与该物种的宠物贸易正在增加，水产养殖生产也很成熟。在这里，我们提供了详细的市场调查和 2018 年 1 月至 2021 年 2 月期间的国内贸易、出口和进口量。塞内加卢斯印度尼西亚采用 MaxEnt 算法进行分析。许多印度尼西亚岛屿的大量区域被确定为适合这种鱼的生存和建立。爪哇和苏门答腊河流中 3 个可能已建立的种群的记录证实了这一点，野生型和白化幼体均被捕获。加里曼丹岛、爪哇岛和龙目岛的当地渔民建议出现更多的野生种群；但是，需要通过未来的实地考察进行验证。P的文化。塞内加卢斯在印度尼西亚不受监管，这种掠食性鱼类的潜在风险及其在这个东南亚国家的潜在传播令野生动物管理者感到担忧。尽管全面禁止似乎是最佳解决方案，但对当地社区的社会经济状况负面影响最小的替代风险缓解策略更为可行。P的白化病表型。塞内加尔的风险可能较小，因为它更容易被捕食者发现，对疾病和压力的敏感性更高，并且社会行为受到干扰。由于白化病在印度尼西亚很流行，在实验证实白化病的较低侵袭性后，建议用这种潜在的侵入性较小的表型替换野生表型。
