This short paper, prepared after the second year of the Fish Survey Project, overviews the RDT and the more quantitative Stationary Sampling Technique. The advantages to the REEF RDT are discussed, including the information provided on fisheries-independent species and its simplicity. The author concludes that both methods can be used to answer a wide variety of monitoring and scientific questions, although each has advantages and disadvantages. Summary posted online at
