Invertebrate fisheries have become increasingly important, economically and ecologically, in world fisheries. Because of unique and often complex life histories and management regulations, the assessment and management of invertebrate species are usually more challenging than those of finfish species. The main objective of this proposed symposium is to provide a platform for overview and discussion of fisheries ecology, assessment methods and management strategies for various invertebrate species (e.g., lobster, crab, shrimp, sea urchin, scallop and so on). Speakers who study different invertebrate species in a wide range of geographic areas from east and west coast US, Hawaii, South America, and Australia have been invited to present their work. The last effort to summarize these issues was at the AFS 2005 annual meeting in Anchorage, AK and focused on crabs only. AFS members and participants will benefit greatly from the discussion of the advanced knowledge in fisheries ecology, stock assessment and management of a diverse array of invertebrate species.
