Abstract

Concentration of zooplankton in a holding zone near the shore during onshore winds may be explained hypothetically by the built-in behaviourial responses of planktonic organisms (particularly crustacean larvae) to landwash vibrations. These responses initiate vertical or other migrations which take advantage of compensatory outward currents and keep the plankton from drifting ashore. Lagoon or estuary entrances change the "noise" pattern and the plankton (especially penaeid shrimp or crab larvae) enter the estuary at the deepest part of such channels with inward tidal flows.
