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

• Baja vs. S. California lobster (biology constant,
  mgt. Different), Maine/Florida?
• Within Baja one fishery vs. another (hold mgt
  constant and letting biology vary)

Information gaps

• Flows in sources and sinks of production/recruitme
  nt.
• 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,
