Prey Quality

Macroalgal and urchin barren communities are alternately stable and persist in the Aleutians due to sea otter presence and absence. In the early 1990s a rapid otter population decline released urchins from predation and caused a shift to the urchin-dominated state. Despite increases in urchin abundance, otter numbers continued to decline. Although debated, prey quality changes have been implicated in current otter population status. This study examined otter prey abundance, size, biomass, and potential energy density in remnant kelp forest and urchin-dominated communities to determine if alternate stable states affect prey quality. Findings suggest that although urchin barrens provide more abundant urchin prey, individual urchins are smaller and provide lower biomass and potential energy density compared to kelp forests. Shifts to urchin barrens do affect prey quality but changes are likely compensated by increased prey densities and are insufficient in explaining current otter population status in the Aleutians.

Empirical Record

Fisheries provide critical contributions to global food security and are important in the fabric of human societies throughout the world. This chapter provides a brief history of fishery development and the evolution of scientific understanding and approaches so critical to effective fisheries management. It shows how processes at the population, community, and ecosystem levels are manifest in complex ways in even simple descriptors such as catch histories. Although many aspects of conventional fisheries management center on equilibrium concepts, the empirical record suggests a much more complex reality with the possibility of alternate stable states and non-linear dynamics. This chapter provides the motivation for exploring alternative models of fishery dynamics in a broader ecological context. Confronting complexity is essential if we are to move toward operational Ecosystem-based Fishery Management on a global basis.
