Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport in the estuary were assembled. The three-dimensional model was used to simulate the transport of weekly larval cohorts. Different larval directed motion hypotheses were tested beginning with the simplest assumption of no directed motion through to larval directed motion into the instantaneous current with larval swimming speed as a function of larval length or age. The latter hypothesis gave the best comparison between the independent model computed results and the observed densities.
