A spatial dynamic multistock production model

We developed a generalized spatial dynamic age-structured multistock produc tion model by linking bioenergetic principles of physiology, population eco logy, and community trophodynamics to a two-dimensional finite-element hydr odynamic circulation model. Animal movement is based on a search of an envi ronmental-habitat feature vector that maximizes cohort production dynamics. We implemented a numerical version of the model and used scientific data v isualization to display real-time results. As a proxy for larger regional-s cale dynamics, we applied the model to study the space-time behavior of rec ruitment and predator-prey production dynamics for cohorts of spotted seatr out (Cynoscion nebulosus) and pink shrimp (Penaeus duorarum) in the tropica l waters of Biscayne Bay, Florida.
