  • 1. The Aquavision concept of organic carp & backyard fish farming With reference to applying a holistic approach to developing aquaculture sustainably Jimmie Hepburn Aquavision
  • 2. What’s on your mind?
  • 3. Or this…….?
  • 4. What’s organic carp or backyard fish farming got to do with saving the planet?
  • 5. The story starts a long time ago…
  • 6. The impact of aquaculture?
  • 7. A whole complex of impacts……
  • 8. MSc in Human Ecology….How canaquaculture inScotlanddevelop towardsustainability?
  • 9. Our remit today is to sketch out a map which could help …….Towards aSustainableFinfishAquacultureIndustry forEngland
  • 10. The “S” word SUSTAINABILITY! We need a direction – we need a map
  • 11. Where will our protein come from in 50 years time? The arrival of the third millennia – when people realised that the world has finite resources and it is our responsibility to manage these resources for future generations We need to avert the collapse of global fisheries through developing a comprehensive sustainable development strategy We will need to develop sustainable aquaculture systems on a massive scale – to feed the world’s population and it’s growing affluence
  • 13. Ecosystem Processes Ecosystem Structure – boundaries & integration Ecosystem Function Cycles and feed back- input / output balance Ecosystem Management within the farm to produce fish products – ecological intensification or diversification
  • 14. Community Processes – how people organise themselves Community processes outside the farm General / global issues on sustainability Sustainability issues Community Specific/ local sustainability processes inside issues the farmPractical The work of sustainable Developing &Solutions development applying theory
  • 15. Intensive or extensive ? Characteristics Extensive Intensive Aquaculture AquacultureInputs Low HighSelf-sufficiency Closed system Open systemWaste Useful - recycled HazardousNo. of Spp. Several OneEnergy input Low HighMarket Near to farm Far away from farmEconomy Subsistence Capital intensiveDiversification Considerable scope Limited scope
  • 16. Semi intensive- the answer?Extensive Semi - intensive Intensive
  • 17. Effective communication We need to speak to the ‘right’ people Information flow in one direction e.g. trade association and regulator Stakeholders not fully integrated People can change there minds e.g. the development of a furunculosis vaccine A question of attitude…knowledge function
  • 18. Effective networking Value of networks Action Centred Networks to reach a decision through consensus – which are characterised by:  Stake holder equity  Multi disciplinary team  Participation / learning essential  Committed to the specific task  Link pin organisation – to drive the initiative through Example: Soil Association development of an organic aquaculture standard
  • 19. How do we put theory into practice? Ideas Feedback Theory NETWORKS Practice Feedback Deeds
  • 20. How sustainable could Upper Hayne be?
  • 21. Organic conversion...why?
  • 22. Organic Regulation 35 certification standards in the world (19 in Europe) 28 are independent organisations (e.g. Soil Association) Problems of harmonisation and dilution of standards

  • 26. Organic Aquaculture Production  UK – current certified fish/shell fish  Salmon  Trout  Charr  Bivalves  Carp
  • 27. Why carp? Not to make a quick buck! Globally carp is farmed and eaten widely A relatively easy species to farm the whole system – sustainably We need to move on from ‘Stone Age’ aquaculture
  • 28. Growing carp organically
  • 29. More questions than answers! Is it possible to fulfil the current organic standard? Adequate and cost effective protein supplements DO levels affecting productivity How to boost productivity of ponds Develop appropriate markets Processing challenges Economic viability of semi intensive carp culture
  • 30. Carp for the table – a future? It can be done and there is a potential market There is a need for enthusiastic producers and researchers to give semi insensitive carp (& other spp.) serious consideration Small scale production?
  • 31. Backyard Fish Farming (BYFF) 2 million garden ponds in the UK A nation of fish keepers or hunters Until now aquaculture has been left to the professionals Is there an opportunity? Definition Existing BYFF
  • 32. Similarities between ornamental fish culture and table fish culture Could be similar sized systems Basic components are the same whether at pond scale or within a recirculation system People are already ‘farming’ fish Can be intensive or extensive grown Must be relative easy to do (yet to be proven by BYFF)
  • 33. Differences between ornamental fish culture and table fish culture  Bio mass  Water quality criteria  Management intensification – e.g. water flows, water use,  Aesthetic e.g. – herbaceous border versus the vegetable patch
  • 34. Two approaches to BYFF Intensive: recirculation system – tank or small pond (up to 35000l) requiring active filtration Extensive: large pond for rearing fish – (above 50m ) 2
  • 35. Species which could be considered for growing in a BYFF system Carp Tilapia Sturgeon Grass carp Tench Catfish Trout Eel Perch Zander
  • 36. Small is beautiful Will not fill the fish protein gap Could be a valuable education tool to raise awareness of the issues & change behaviour? Rising interest – courses at Upper Hayne – people wanting to do a wide range of projects, could this help to solve the problem?
  • 37. Has the problem been solved? Not yet! For aquaculture in England to develop sustainably, a holistic approach is needed in all the main spheres (e.g. social, economic, ecological etc.) and in addition, must be driven by committed effective networks – all for the benefit of our future generations The aquaculture of the future will likely play an increasingly wider role – farming our still freshwaters or growing fish in our back garden are just two such examples!
