Fisheries impact on forage fish. Forage fish impact on the primary fisheries.

Benguela Current upwelling (Anchovy collapse)
Discussion of: Prey switching impact?
Wasp-waist ecosystems
Ecopath/ecosim vs Atlantis
Questions:
Can we identify the nature of control?
Importance of wasp-waist control.
regime switching
Negative impact of forage fish on ground fish. e.g. Iceland appearance of mackerel in their waters. Can they fish it as an invasive
Groundfish, like cod, can eat primarily forage fish, or invertebrates
Big gaps:
- modeling tools, non-equilibrium.
- examples where forage fish collapse
- variability, impact of variability.
- Where the heck are the innate oscillations.
