Abstract
We report on twelve larval fish taxa, plankton vol- ume, and total larvae caught in monthly ichthyoplankton tows in King harbor, Redondo Beach from 1974–2009. Plankton volume, total larvae, and all but three taxa sig- nificantly declined throughout this study. larval declines were primarily correlated with plankton volume and negatively correlated with a rise in sea surface temper- ature (sst).taxa that did not decline were gobies and Hypsypops rubicundus. localized processes, red tides, and other episodic events appeared to be associated with annual failures in larval production.With the exception ofnegativecorrelationswithsst,oceanographicmetrics (mei, PDo, nPGo, nPi, and CUi) were not correlated with larval catch for individual taxa. instead, sst, CUi, and mei may be explanatory for the decline in plankton volume. Plankton volume was a potential major driver in the overall decline in ichthyoplankton observed dur- ing this study.
