define sustainable harvest
Define Sustainable Harvest
  • Reproduction and biomass – assure future supply
  • Ecosystem – Beds continue to fulfill their role of habitat, food, competition… even with harvest.
  • Economic – cost and quality
  • Employment – how many jobs? how much income?
case study norwegian laminaria hyperborea
Case Study – Norwegian Laminariahyperborea
  • Started in 1960’s
  • Company initiated plan.
  • Based on understanding biology, ecology, substrate and ecosystem…
  • Pronova (now FMC BioPolymer) is the only harvester.
  • 5 year cycle so 5 zones.

case study norwegian laminaria hyperborea1
Case Study – Norwegian Laminariahyperborea
  • Government approved management plan in 2002.
  • Must stay engaged with politicians and environment/fisheries agencies.
case study chilean sarcothalia crispata
Case Study – Chilean Sarcothaliacrispata
  • When started, in 1970’s, based on collecting beach material.
  • Mature plants, completed life cycle, harvested by wave action.
  • Carrageenan yield and gel strength/viscosity were very attractive.

Case Study – Chilean Sarcothaliacrispata
  • Increased demand led to diver harvesting in 1990’s and more buyers.
  • Removing younger plants and substrate.
  • Lower carrageenan yield and extract quality.
  • Lower populations?
  • Poor post harvest handling.
  • Chile trying community based management plan.

  • Kelp Industries Ltd. is only buyer.
  • Harvested as storm toss on beach.
  • Sustainable since 1976.
summary of case studies
Summary of Case Studies
  • One buyer/harvester with active harvesting (Norway).
  • Many buyers/harvesters with active harvesting (Chile).
  • One buyer/harvester with passive harvesting (Australia).
lessons from fisheries management
Lessons from Fisheries Management
  • One buyer/harvester and passive harvesting are easily sustainable.
  • Numerous buyers/harvesters with active harvesting needs good manageemnt and enforcement. How?
lessons from fisheries management1
Lessons from Fisheries Management
  • Concessions?
  • Education?
  • Buyer based management (diver protocol, fishing season)?
  • Co-Management?
  • Hatchery seeded beds and leasing production areas.
  • Quota?
  • Community based management?
  • Permits?
  • Shares?
  • Purchase right to harvest?
conclusion
Conclusion
  • Ownership = responsibility
  • No shortcuts
  • Corruption attitude leads to shortcuts which ultimately destroy populations and ecosystems.
  • Approach can depend on level of quality governance, cultural attitudes, financial resources…
  • With limited Government resources, probably best to be self policed within biological constraints.
conclusions
Conclusions
  • Learn from other natural resource management plans… not just seaweed.
  • Each situation is unique due to biology, culture of residents, government resources…
  • Need communication and “work in progress” attitude. No one will get all they want and not every initiative will work. But “nothing ventured, nothing gained.”
