The non-linear response of plankton to wind mixing events — implications for survival of larval northern anchovy

Received on January 1, 1986; accepted on September 1, 1986 A one-dimensionsal (z, t) plankton model incorporating mixed layer dynamics suggests die following: wind events can be detrimental to larval northern anchovy, Engraulis mordax, which need to feed on concentrations of plankton localized within the water column. Wind mixing dissipates vertical structure in prey distributions. Interacting biological and physical processes determine the time interval before high concentrations of prey are re-established, i.e. the starvation period endured by the anchovy larvae. Phytoplankton growth, herbivore grazing and reproduction, and plankton vertical migration govern the rate of re-establishment of vertical structure in plankton distributions, once wind conditions allow turbulence in the upper water column to dissipate. If there is a net nutrient flux into the euphotic zone, local concentrations of prey after the wind event may be higher than before the event. This may enhance larval anchovy survival, providing the starvation period is not too long.
