Corroborating effort and catch from an integrated survey design for a boat-based recreational fishery in Western Australia

•an off-site recreational fishing survey was tested with a corroboration study.•data and estimates were compared with concurrent on-site survey and remote camera.•distributions of catch raw data were similar among surveys.•estimates of effort and catch of most demersal and nearshore species were comparable.•effort data from remote camera mitigated measurement bias from on-site survey.
