Specifically, observations on behavioral characteristics of various stages and species of zooplankton and fish larvae are needed, including daily ambits (range of operation) of respective species and vertical distributions of zooplankton, their food and their predators over time. Variability of these should be investigated in conjunction with physical variables such as temperature; this would include species- and stage-specific aggregation dynamics.
To develop models, functional relationships for zooplankton behavior, shear and turbulence have to be obtained; and real-world small structure and small-scale processes have to be adequately addressed in such models. It is at these scales that the interactions between the various components of the plankton occur. It is also these scales about which our knowledge is severely limited. An understanding of mechanisms governing animal's existence at small scales, as mentioned earlier, is essential to comprehend processes on much larger scales.
