The Aqua-vision concept of organic carp and backyard fish farming

  1. 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. 2. What’s on your mind?
  3. 3. Or this…….?
  4. 4. What’s organic carp or backyard fish farming got to do with saving the planet?
  5. 5. The story starts a long time ago…
  6. 6. The impact of aquaculture?
  7. 7. A whole complex of impacts……
  8. 8. MSc in Human Ecology….How canaquaculture inScotlanddevelop towardsustainability?
  9. 9. Our remit today is to sketch out a map which could help …….Towards aSustainableFinfishAquacultureIndustry forEngland
  10. 10. The “S” word SUSTAINABILITY! We need a direction – we need a map
  11. 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. 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. 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. 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. 16. Semi intensive- the answer?Extensive Semi - intensive Intensive
  17. 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. 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. 19. How do we put theory into practice? Ideas Feedback Theory NETWORKS Practice Feedback Deeds
  20. 20. How sustainable could Upper Hayne be?
  21. 21. Organic conversion...why?
  22. 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. 26. Organic Aquaculture Production  UK – current certified fish/shell fish  Salmon  Trout  Charr  Bivalves  Carp
  27. 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. 28. Growing carp organically
  29. 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. 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. 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. 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. 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. 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. 35. Species which could be considered for growing in a BYFF system Carp Tilapia Sturgeon Grass carp Tench Catfish Trout Eel Perch Zander
  36. 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. 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!
