Simple Indicators for Sustainable Fisheries

  1. 1. Start-up Meeting Presentations Before and after WP meeting INCOFISH WP 7
  2. 2. Simple Indicators for Sustainable Fisheries Project Objectives INCOFISH WP 7
  3. 3. 3 Outline • WP Goal • List of WP members • Brief introduction to indicators concept • WP objectives and deliverables • WP milestones and time table • Open discussion
  4. 4. 4 WP 7 Goal Identify, apply, and evaluate the use of indicators that have the potential to end overfishing
  5. 5. 5 WP 7 Members are: • Joe Ryan • Mauricio Castrejón • Graham Watkins • Birane Samb • Rainer Froese • Amanda Stern-Pirlot • Michael Ballón • Carlos Benites-Rodriguez • Lynne Shannon • Vachira Lheknim • Graham Pierce • Cristina Pita CABAL S.A., Nicaragua CDF CDF CRODT, Senegal IfM-GEOMAR IfM-GEOMAR IMARPE, Peru IMARPE MCM DEAT, So. Africa PSU, Thailand UNIABDN, Scotland UNIABDN
  6. 6. 6 Simple indicators Fisheries management is not working: • Top-down control • Informed solely by info. from fisheries biology • Complex, costly, largely incomprehensible Simple indicators: • Reflect condition of fishery • Rely on low-cost observations • Can be accepted and applied by stakeholders and public • Conform to “Pressure, State, Response” framework
  7. 7. 7 “Let them spawn!” • Indicator: Percentage of mature fish in catch (target = 100%) • Response: Fish ruler demarcating minimum length for mature fish
  8. 8. 8 PSR Framework PRESSURE Recruitment Overfishing (the taking of immature fish) STATE Percent mature fish in catch tool: fish-ruler RESPONSE “Let Them Spawn!” awareness campaign Tool: fish-ruler
  9. 9. 9 WP 7 Objectives • Identify suitable indicators • Establish parameters needed for indicators for all relevant species/fisheries • Test management by indicators with stakeholders and public • Analyze progress and problems
  10. 10. 10 WP 7 Deliverables • Review of existing indicators and selection of suitable, simple indicators (Month 7) • Database to make available the parameters needed for application of indicators (Month 13) • Web-tool to assist in the application of indicators (Month 19) • Test of indicators with real-world fisheries and stakeholders—final report (Month 34) • The Big 5
  11. 11. 11 WP 7 Milestones • 1st Workshop (now) • 2nd Workshop (Month 20)
  12. 12. WP7 Meeting Outcomes
  13. 13. 13 In attendance: Mauricio Castrejón, CDF Vachira Lheknim, PSU Christina Pita, UNIABDN Graham Pierce, UNIABDN Henn Ojaveer, MEI Carlos Benites, IMARPE Michael Ballón, IMARPE Rainer Froese, IfM-GEOMAR Amanda Stern-Pirlot, IfM-GEOMAR
  14. 14. 14 Agreed-upon criteria Indicators should be: 1. Observable by stakeholders, either directly or through a transparent process 2. Understandable 3. Acceptable by fishers and public at large 4. Efficient and within economic resources for research on a sustained basis 5. Related to management and have responding management measures (PSR framework) 6. Valid—e.g. accurately reflecting the state of the resource
  15. 15. 15 Selected Indicators: Indicator Required Data Possible responses 1 % of mature fish in catch (goal 100%) Mean length in pop. or mixed fishery Lm (also eventually length where 90-100% are mature) length frequency of catch Promote capture of mature fish through Fish ruler and info sheet for fish traders 2 % of ‘optimum’ size in catch (goal 100%) Length-frequencies from catch or surveys Length-weight relationship for species Same as above 3 % “mega spawners” in catch (% size above optimum length plus 10%) (goal 0%) Mean max. length in pop or mixed fishery Length-frequencies from catch and surveys MPAs Campaign “Let Megaspawners live” Only catch cohorts after 1st and before 2nd spawning 4 % Bycatch in total catch Possibly “charismatic” spp. in bycatch Bycatch biomass by fishery Awareness/ “propaganda” campaign
  16. 16. 16 Probable target fisheries: Galapagos: Lobsters, Sea Cucumbers Peru Hake, Lumptail Searobin, Peruvian Rock Seabass, Peruvian Banded Croaker Scotland Haddock, Whiting, Nephrops, Squid, Some Portuguese species? Thailand Prawns, some fish Nicaragua Littoral demersals, Lobsters? Baltic Maybe Zander, Perch, Herring?
  17. 17. 17 Next Steps: • Each member to assemble data necessary to apply indicators to his/her fisheries for web portal (L-F, maturity, bycatch) Deadline: Month 13 (Next March/April) • Start thinking about response implementation • Keep in touch with other WPs re their indicators—can we draw correlations?
  18. 18. 18 General Remarks Easy part is first: The harder part is in implementation– most of the concerns among WP members and others concerned approaches to using indicators in mgmt. We will mostly collaborate with other WP indicator- related objectives in relation to and combination with our selected indicators and overfishing– we’re not an indicator clearinghouse.
