Annotation	We tested different sampling methods to reduce fright bias in age-0 fish. Experiments using video recordings demonstrated that efficiency was 13% for extension pole electrofishing (EPE), 47% for thrown anode electrofishing (TAE), and 100% for pre-positioned anode electrofishing (PAnE). A modified PAnE sampling design was tested against EPE, TAE, and fine-mesh seine netting (SN). We found that PAnE sampled significantly more species and individuals than EPE and TAE. Assemblage structure sampled by PAnE differed significantly from that sampled by EPE, TAE, and SN; the difference was more substantial relative to SN than to EPE or TAE. Although the modified PAnE design demonstrated significantly reduced time consumption, it was still more time consuming than the other sampling methods. The apparent advantages of PAnE were its high relative efficiency and its minimization of the bias and selectivity caused by the investigator’s presence or action.
