Session 8
Interactions between gadoids and crustaceans: The roles of climate, predation, and fisheries


AnneDorte Burmeister (Greenland )
Earl Dawe (Canada)
Franz J. Mueter (USA)
Olafur Palsson (Iceland)

Invited Speakers:

Patrick Ouellet (Canada) - presents on May 24, Plenary Session
José M. (Lobo) Orensanz (Argentina) - presents on May 24, Plenary Session

In this session we seek papers that document and investigate the processes that lead to shifts between demersal fish, especially gadoids such as cod and pollock, and crustaceans, such as shrimp and crabs. What role does gadoid predation play on the dynamics of shrimp and crabs? How does this compare to the influence of climate regimes or the effects of industrialized fishing? How does the spatial overlap between gadoids and crustaceans change seasonally and annually? Papers that address these questions either within a single ecosystem or compare different sub-Arctic regions are sought.
