Combining seabird diet, acoustics and ecosystem surveys to assess temporal variability and occurrence of forage fish

The abundance and distribution of Northern anchovy (Engraulis mordax) and young of the year (YOY) rockfish (Sebastes spp.) are critical for the survival and reproduction of seabirds, mammals, and predatory fish within the California Current Ecosystem. Traditional detection and quantification of forage fish by trawling can be time consuming and expensive, and may not provide the spatio-temporal resolution needed to examine ecological...
