Shipping is recognized as a major vector for the global transfer of non-indigenous marine species (NIMS). As a major transshipment port, Singapore can minimize the risk of NIMS transfer by implementing pragmatic management strategies, such as using vessel movement information to assess the risk of NIMS transfer. Findings from vessel movement information in a major port terminal in Singapore showed that vessel residence time is short, with >92% of vessels spending seven days or less. There was little variation in vessel residence time to vessel arrival numbers, while the top three last ports of call were found to be from regional ports. Using two key features obtained from vessel movement records, 1) vessel residence time and 2) biogeographic origin of the vessels' last port of call, a simple risk assessment matrix was constructed and applied to assess the level of risk of NIMS transfer by transiting vessels.
航运被公认为非本地海洋物种（NIMS）全球转移的主要载体。作为一个主要的转运港口，新加坡可以通过实施务实的管理策略来将 NIMS 转移的风险降到最低，例如利用船舶移动信息来评估 NIMS 转移的风险。从新加坡一个主要港口码头的船舶移动信息中发现，船舶停留时间很短，超过 92%的船舶停留时间不超过七天。船舶停留时间与船舶到达数量的变化很小，而前三个最近的停靠港口均来自区域港口。利用从船舶移动记录中获得的两个关键特征，1）船舶停留时间和 2）船舶最近停靠港的生物地理起源，构建了一个简单的风险评估矩阵，并应用于评估过境船舶 NIMS 转移的风险水平。
