| Abstract: | The seasonality and abundance patterns of ichthyoplankton were investigated during 1985–1986 in Great South Bay, New York, USA. Eggs representing 17 species and larvae representing 23 species of fish were identified. Bay anchovy, Anchoa mitchilli, was the most abundant ichthyoplankter, comprising >96% of the eggs and >69% of the larvae collected. Bay anchovy spawned throughout the bay from late May through August, with peak baywide densities of >200 eggs and 6 larvae m?3. Eggs of windowpane flounder (Scophthalmus aquosus) ranked second in abundance and were present in both spring and fall. Other dominant larvae were winter flounder (Pleuronectes americanus) and American sand lance (Ammodytes americanus). Their combined density reached 8 m?3 and accounted for the winter peak in larvae. The seasonality of abundance of larval fish was strongly correlated with reported densities of copepod nauplii prey. |
