The low-frequency variability of small pelagic fish abundance is one of the most emblematic and best-documented cases of fish population fluctuations not explained wholly by fishing effort. Over the last 25 years, diverse observations have been integrated into several hypotheses; however, due to limited-duration time series, hypothesis testing has proven extremely difficult with the available statistical and empirical tools. As a result, the mechanistic basis for how the physics, biogeochemistry, and biology interact to result in the various patterns of synchronous variability across widely separated systems remains unknown. Identification of these mechanisms is necessary in order to explore projections and to build scenarios of the amplitude and timing of stock fluctuations, and their responses to human interactions (fisheries) and climate change. The workshop aims to bring and compare state-of-the-art modeling tools and discuss on expertise to tackle this important scientific and environmental problem.

The workshop will likely produce a review paper on state-of-art models for coupled physical and biological (including higher trophic level) systems. It is also expected that papers presented at the workshop will be submitted for publication in the Symposium volume.
