5 What makes a successful fishery? Georgina: economically profitable, socially beneficial (working together, political.., equity, employment), environmentally healthy (no ecological damage, sustainable,…). Economic: maximizing rents (profits) – could be measured with readily available data. Biological: persistence of population (low extinction risk), contribution to biodiversity/community dynamics Social: employment, income distribution, quality of life, institutions and ability to adapt, can institutions lead to self-governance, level of compliance. Local: high abundance, high catch (relative to recent history) “good season or bad season”, sustained, but may boil down to revenues. Consumer: fresh, high quality product, size might matter.

6 Is the lobster fishery successful? Generally, yes – especially red lobster. –Might be certified by Marine Stewardship Council as green fishery. Possible differences in success along coast. In south, there is a sense that the success is falling.

7 Hypotheses Geographic etc. conditions are relevant to success. Physical conditions (e.g. Remoteness) Social history of community Biological: humans do not know where massive recruitment takes place. Relatively undisturbed. Well-monitored (but enforcement varies along coast) Are feedbacks tight or loose within community? Feeding small lobster with bait. Traps not trawls.

8 Some comparative analyses 1.Baja vs. S. California lobster (biology constant, mgt. Different), Maine/Florida? 2.Within Baja: one fishery vs. another (hold mgt constant and letting biology vary)

9 Information gaps Flows in sources and sinks of production/recruitment. Market structure/outlets History/kinship structure of coops. Operating costs Data on monitoring and enforcement Methods to estimate illegal (unreported) harvest Cooperatives: size, social structure, self- enforcement, labor organization, income,
