  abstract = {{A}ccidental introductions of non-native species into aquatic environments often result in invasive populations that cause substantial conservation concerns. {T}hey account for 8% of all fish introductions and often occur when fish consignments are intentionally released into the wild (stocked') but are unknowingly contaminated with a hitch-hiking' species that is also released.{T}his study tested the efficacy of a fish stocking audit procedure in preventing the introduction of a model hitch-hiking fish ({P}seudorasbora parva) within a batch of model native fish ({R}utilus rutilus). {I}t was tested in relation to different {P}. parva contamination levels (1, 5, 10, 20%), auditor expertise ({E}xpert, {I}ntermediate, {N}ovice) and search effort.{T}here was considerable variability in the detection thresholds among contamination levels, auditor experience and search effort; false-negative recordings reduced as all these parameters increased. {P}robability of {P}. parva detection ({POD}, 0 to 1) showed that at the lowest search effort, {POD} was greater than 0.80 for {E}xpert auditors only when contamination levels exceeded 10%. {A}t the highest search effort, {POD} was greater than 0.80 at the 1% contamination level for {E}xperts, but was at 3 and 8% contamination for {I}ntermediates and {N}ovices.{T}hus, while small non-native fishes are at risk of being accidentally introduced owing to their difficulty of detection in stocking consignments, an effective audit procedure using experienced auditors and high search effort reduces this risk. {I}mplementation should help prevent subsequent invasions, protecting native species from their adverse ecological consequences.},
