Current Management OBJECTIVE Create a tool to help the GNP evaluate the health of the fishery and design a management plan that is science-based and resource efficient. MOTIVATION Current Management 4 Months 46 Tons
Potential for Data-Limited Assessment OBJECTIVE Create a tool to help the GNP evaluate the health of the fishery and design a management plan that is science-based and resource efficient. MOTIVATION Data Limited Assessment Cost effective Easy to use Efficient data collection Annual evaluation
Capacity Building Timeline Phase 1: GROUNDWORK June 2011 - April 2013 Phase 2: IMPLEMENTATION April 2013 December 2014 Phase 3: REEVALUATION & CONTINUED SUPPORT January 2015 - Present
Capacity Building: Phase 1 GROUNDWORK Relationship with Conservation International & Stakeholders Proposal suggestions 3 Trips to Galápagos Collection of existing data
Capacity Building: Phase 2 IMPLEMENTATION Team of 5 scientists to Galápagos for 7 weeks Stakeholder engagement Compilation of new & existing data Tool design
Methods: Data Poor Assessments 12 Poten1al DLAs Criteria Reliability Biases Inputs Cost Output LBSPR LBAR Catch Curve Applied Various Databases Ran in R and Excel Compared Fishery Indicators (F/M, F, SPR) Catch Curve
Results: Data Limited Assessment Outputs F/M: Males Only 2.5 120000 2 100000 F/M 1.5 1 80000 60000 40000 Landings (MT) Catch Curve Landings 0.5 20000 0 0 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 Year

Control Rule
Capacity Building: Phase 2 IMPLEMENTATION Training workshop with stakeholders Control rule development for management Sampling protocol designed for management objectives
Sampling Protocol Better Data Collection Standardization Randomization Sample size 2000 lobsters per island Better bookkeeping Export, gifts, sold locally Zero tolerance 26 cm minimum
Capacity Building: Phase 3 REEVALUATION & CONTINUED SUPPORT Political turnover Retraining of new staff Additional workshop (Summer 2015) Analysis of sampling protocol success & failures Potential application to other fisheries
ASSESSMENT TOOL Historical insights Future trends CAPACITY BUILDING Start basic Time & stakeholder engagement SAMPLING PROTOCOL Quality over quantity
