Invasive non-indigenous species (NIS) are a threat to marine biodiversity and marine reliant industries. Recreational vessels are recognised as an important vector of NIS translocation, particularly domestically. This paper reports on a novel application of multilevel modelling and multiple imputation in order to quantify the relationship between biofouling biomass (wet weight) and the vessel-level characteristics of recreational and fishing vessels. It was found that the number of days since the vessel was last cleaned strongly related to the biofouling biomass, yet differed dependent on vessel type. Similarly, the median number of trips undertaken was related to the biofouling biomass, and varied according to the type of antifouling paint (AF) used. No relationship was found between vessel size and biofouling biomass per sample unit. To reduce the spread of NIS, vessel owners should use an AF paint suitable to their vessel's operational profile, and follow a maintenance schedule according to the paint manufacturer's specifications.
入侵性非本地物种（NIS）对海洋生物多样性和海洋依赖型产业构成威胁。休闲船只被认为是 NIS 转移的一个重要载体，尤其是在国内。本文报告了一种新的多层次建模和多重插补的应用，以量化生物污垢生物量（湿重）与休闲和渔船船舶水平特征之间的关系。研究发现，船只上次清洁后的天数与生物污垢生物量密切相关，但取决于船只类型。同样，船只进行的平均航次数与生物污垢生物量有关，并且根据使用的防污漆（AF）类型而有所不同。在样本单位中，没有发现船只大小与生物污垢生物量之间的关系。为了减少 NIS 的传播，船东应根据其船只的操作情况选择合适的 AF 涂料，并按照涂料制造商的规格制定维护计划。
