Abstract: Electronic monitoring has recently become an important topic in commercial fisheries. While most discussions tend to focus on the hardware and management aspects, it seems easy to overlook a crucial element of any electronic monitoring program: the point at which data are captured during the human conducted review of collected video and sensor data. Specialized software is important for expediting the review of raw video data since the integrated features and efficiency of the software affect the resulting review times, and therefore the cost of review, as well as overall data quality. Pre-analysis review of electronic monitoring data could be improved by further research and development of specialized software, and attempts to solve the already existing problems facing current programs. With these improvements, the review of raw data from electronic monitoring systems may become more efficient, and the resulting data more reliable.
