Description cont’d Markets Social organization & history
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.
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.
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.
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)
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,
