Past research on similar species leads one to surmise that fluid motion is likely to have profound influence over virtually all aspects of their life histories. However, the flow biology of many invertebrates of biochemical interest is completely unknown. This research is to develop a system that is capable of detecting sensitivity and dependency on flow in benthic marine invertebrates currently in aquacultural development. This technology will be used in commercial aquaculture development as a tool for bringing new benthic invertebrate species into culture, and for defining flow conditions of optimal biomass and natural product yield in aquaculture.
