Description:Since 2010, SERFS videos are read using the MeanCount approach described by Schobernd et al. (2014). MeanCount is used to index the relative abundance of approximately 100 priority species that are high priorities for management. Beginning in 2015, an additional component was added to video reading, which was noting the presence or absence of nearly all fish taxa over the entire 20-minute interval of time within which MeanCount occurs. This additional presence-absence video reading component has been extremely useful and has resulted in new knowledge of reef fish in the region (e.g., Bacheler 2019, 2022). However, SERFS typically records much more bottom footage than is currently read.
