Description

Abstract: Ocean recreational fishing in the United States is monitored less rigorously than commercial fisheries. Video technology has been shown to be an effective tool for monitoring many commercial fisheries; it increases monitoring coverage, improves catch accounting, and can substantially reduce monitoring costs. This study investigated video monitoring as a tool to improve recreational fisheries effort estimates and reduce monitoring costs for management. Three cameras linked to a digital video recorder were used to monitor ocean recreational boats departing from Newport, Oregon. No statistical difference was found between the video method and the traditional sampler method for counting departing boats from dawn to 10:00 AM. However, a significant difference was found between the methods for estimating total daily boat effort. The traditional method of expanding sampler counts for unmonitored times underestimated daily boat effort in 89% of the cases relative to the 24 hour video monitoring census. These findings imply that the difference between effort estimation results was the expansion methodology. A cost-benefit projection showed video monitoring could provide significant savings. The annual cost to video monitor boat effort in one port was estimated to be 63% less than the traditional method. This study showed that video monitoring can increase the accuracy of the daily effort estimates and, at the same time, reduce program costs over the long term.
