Technology for studying the marine environment has been rapidly diversifying over the past few decades. These technologies can be applied to a wide range of marine environments and are relevant to many of the contemporary challenges facing decision makers with managing commercial fisheries or ecosystems. The Florida Fish and Wildlife Conservation Commission has been studying reef fish spawning aggregations in the Florida Keys for over a decade using many different technologies; some with more success than others. Here we discuss lessons learned from many different partnerships using diverse approaches such as: split beam surveys, diver surveys, stereo cameras, ROVs, wave gliders, and acoustic telemetry. We explore what tools were more effective for informing management and ideas for introducing new technology in future research. This overview provides insight into the important role that technology plays in the research and management of marine fisheries with emphasis on snapper and grouper fisheries.
