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.
