Uncovering the presence, movements and interactions of aquatic species using new manual and video-based techniques of observation.
Tracking the presence, movements and interactions of aquatic species can not always be done manually by a snorkeller or SCUBA diver. In some settings, it may be unsafe for a human observers to be underwater for long periods of time. Alternatively, the species of interest may be elusive, or the activity may be too quick for the human eye to record. In these circumstances we can turn to digital video technology. In this project we are hoping to explore the effectiveness of underwater video technology for observing aquatic species relative to more traditional techniques. Some recent examples of this can be seen in our surveys of the threatened Murray River crayfish (Fulton et al. 2012, see video) and stream fauna within thick tropical rainforest (Ebner et al. 2014).
