We developed a generalized spatial dynamic age-structured multistock production model by linking bioenergetic principles of physiology, population ecology, and community trophodynamics to a two-dimensional finite-element hydrodynamlc circulation model. Animal movement is based on a search of an environmental-habitat feature vector that maximizes cohort production dynamics. We implemented a numerical version of the model and used scientific data visualization to display real-time results. As a proxy for larger regional-scale dynamics, we applied the model to study the space-time behavior of recruitment and predator-prey production dynamics for cohorts of spotted seatrout (Cynoscion nebulosus) and pink shrimp (Penaeus duorarum) in the tropical waters of Biscayne Bay, Florida.
