Examples of “closed” fish farms <ul><li>The following pictures will show some buildings and overviews of closed fish farms. </li></ul><ul><li>Closed fish farms are fish farms with an own water purification system. </li></ul><ul><li>We call them R.A.S. or Recirculating Aquaculture Systems. </li></ul>

  14. 14. Overview of a biological filtration system
  15. 15. Overview of a biological filtration system
  16. 16. Why closed re-circulation fish farms? <ul><li>By several reasons it is not always </li></ul><ul><li>possible to get all year round wild catch </li></ul><ul><li>quality fish. </li></ul><ul><li>This can be by environmental issues </li></ul><ul><li>or over fishing of waters or catch </li></ul><ul><li>regulations or catch declining or </li></ul><ul><li>logistical issues. </li></ul><ul><li>The consumer however demands all year </li></ul><ul><li>round “quality fish”. </li></ul>
  17. 17. In a closed system there is a high production of quality fish on a relatively small area.  In a closed system, there is independent of the location; all year round a constant production of high quality fish while farming in a closed system is independent of climate and environment. 
  18. 18. It is always summer in a closed recirculation fish farming system.
  19. 19. Some interesting species for Recirculating Aquaculture Systems <ul><li>Anguilla Anguilla Anguilla Japonica </li></ul><ul><li>Catfish Cobia </li></ul><ul><li>Pike Perch Salmon </li></ul><ul><li>Sea Bass Sea Bream </li></ul><ul><li>Seriola Sturgeon </li></ul><ul><li>Trout Tilapia </li></ul><ul><li>Turbot White Fish </li></ul>
  20. 20. <ul><li>Keep in mind two major point: </li></ul><ul><li>To make farming profitable you must farm a higher priced fish </li></ul><ul><li>or </li></ul><ul><li>Fast growing fish. </li></ul><ul><li>A combination of these two issues is optimum. </li></ul>
  21. 21. Koi in re-circulation
  22. 22. White Fish in re-circulation
  23. 23. Eel in re-circulation
  24. 24. Sturgeon fingerlings in re-circulation
  25. 25. Sturgeon in re-circulation
  26. 26. Tilapia in re-circulation
  27. 27. Water and energy savings in RAS <ul><li>Compare to open systems there are major </li></ul><ul><li>water and energy savings in R.A.S. </li></ul><ul><li>Instead of a few hundred m3 per kilogram </li></ul><ul><li>produced fish in flow-through systems we </li></ul><ul><li>need only 50 to 300 litres new water per </li></ul><ul><li>kilogram produced fish in R.A.S. </li></ul><ul><li>In R.A.S. we come with extra filtration even </li></ul><ul><li>come close to zero new water requirement. </li></ul>
  28. 28. Looking at the costs for such an extra filtration unit and the increasing production costs we usually will accept new water intakes up to 300 litre per kilogram feed. Compared to a “controlled” open system, we can save on heating or cooling costs by constant mechanical and biological filtration and by re-circulating the water. 
  29. 29. Re-circulating aquaculture systems are the solution for fish production on all locations in all countries.  In for example Chile; the control on the health of the fish in the pre-growing phase in open waters has led to major problems. In a re-circulation system it’s easier and better to produce salmon fingerlings and salmon smolts than in the lakes.
  30. 30. <ul><li>HESY made two salmon fingerling farms </li></ul><ul><li>150 km away from Punta Arenas in the </li></ul><ul><li>middle of nature. We produced the </li></ul><ul><li>electricity and Oxygen by generators. </li></ul><ul><li>If it is no technical problem to do it there, </li></ul><ul><li>you can farm on almost each spot of the </li></ul><ul><li>world. </li></ul><ul><li>But always keep an eye on the cost price </li></ul><ul><li>and market price and the costs to bring </li></ul><ul><li>the product to the market.     </li></ul>
  31. 31. <ul><li>For our West European countries it is the </li></ul><ul><li>environment and climate that bothering </li></ul><ul><li>us, too many changes in the temperatures </li></ul><ul><li>and environmental restrictions have </li></ul><ul><li>pushed us into the direction of </li></ul><ul><li>re-circulation aquaculture technology. </li></ul><ul><li>This has also a positive effect while we </li></ul><ul><li>have gained the knowledge for R.A.S. </li></ul>
  32. 32. In dry countries like Africa or Australia and several Mediterranean countries water is a major problem while there is a lack of rain and evaporation of water in ponds and lakes is enormous. To establish new flow through systems in these countries is not acceptable for economical reasons, financial reasons and environmental reasons. Water uses for farming are often not allowed and water costs are too high.
  33. 33. <ul><li>Solution to supply anywhere and at </li></ul><ul><li>anytime a perfect product to the market: </li></ul><ul><li>Recirculating Aquaculture Systems </li></ul>
  34. 34. Open sytems <ul><li>In a RAS it’s always summer and all is </li></ul><ul><li>“ controled” by optimum feeding, optimum </li></ul><ul><li>FCR, optimum growth. </li></ul><ul><li>In open systems we have to face several </li></ul><ul><li>“ negative” issues: </li></ul><ul><li>Weather conditions. </li></ul><ul><li>Water quantities. </li></ul><ul><li>Water temperatures. </li></ul><ul><li>Water qualities. </li></ul>
  35. 35. <ul><li>But also: </li></ul><ul><li>Work conditions. </li></ul><ul><li>Environmental problems at intake and </li></ul><ul><li>outflow water. </li></ul><ul><li>Control of water flows. </li></ul><ul><li>Control of Oxygen. </li></ul><ul><li>Growth speed and growth ratio. </li></ul><ul><li>Worse FCR than in R.A.S. </li></ul>

  37. 37. Eel feeding in open system
  38. 38. Open system for Trout in China
  39. 39. Open system for Trout in China
  40. 40. Open farm for White fish in Finland
  41. 41. So no disadvantages at all? It’s hard to find disadvantages in a closed re-circulating fish farm but we have a few attention points. Despite we are able to farm several interesting species on a constant optimum temperature without environmental problems, we believe there is a need for “real specialists” in this technology.  
  42. 42. <ul><li>To run a re-circulation system you need a </li></ul><ul><li>high start-up capital for building -, </li></ul><ul><li>installation- and running- costs. </li></ul><ul><li>  </li></ul><ul><li>In open systems the running costs can be </li></ul><ul><li>significant lower than in R.A.S. </li></ul><ul><li>HESY can, with their technology, compete </li></ul><ul><li>in costs price with cage farming and pond </li></ul><ul><li>farming or flow through systems.  </li></ul>
  43. 43. Procedure to set-up a fish farm Enough willingness to give up a secured life for an less sure future. The job of fish farmer is interesting and the profits are usually good but working with life stock can be also a risk.   Enough financial backing by own capital and/or bank, eventual subsidies must be an extra, never the foundation of a business.  
  44. 44. <ul><li>To establish a farm you need, wherever in </li></ul><ul><li>the world; building licences and </li></ul><ul><li>environmental licences. </li></ul><ul><li>  </li></ul><ul><li>Take care of a reliable energy sources and </li></ul><ul><li>water sources. </li></ul><ul><li>  </li></ul><ul><li>Make a choice on the fish you want to </li></ul><ul><li>farm in relation to your own feeling, the </li></ul><ul><li>market and the water source. </li></ul>
  45. 45. Take care of reliable supply for eggs, fry or fingerlings. Contact feed suppliers and demand assistance on feed regimes. Take care of regular Oxygen supply.   Make contacts and eventual contracts for the sales. Find a good supplier of a fish farming system or fish farming elements.  
  46. 46. <ul><li>Ask for references and try to make visits </li></ul><ul><li>to an existing farm. Only accept a system </li></ul><ul><li>when it includes a good training and after </li></ul><ul><li>sales service.   </li></ul><ul><li>Still when everything seems under control </li></ul><ul><li>you need some luck while, you work with </li></ul><ul><li>life stock, an accident can always happen. </li></ul><ul><li>Insurance companies are getting attracted </li></ul><ul><li>to this industry so it is possible to cover </li></ul><ul><li>some of the risks. </li></ul>
  47. 47. To get licences and grants? Start with your own local government and make them part of your plan. Hopefully they get excited about your plan and see the advantage to have a fish farm in their community. New employment is often a main issue. Follow all the procedures despite they often take a lot of time, but if you can full fill all the demands of the law you will get the licences.
  48. 48. <ul><li>Usually the decision makers have no know </li></ul><ul><li>how of R.A.S. technology so inform them </li></ul><ul><li>well to get to your goal. </li></ul><ul><li>  </li></ul><ul><li>Some countries have grants for R.A.S. </li></ul><ul><li>If you can get a grant; follow the rules and </li></ul><ul><li>try to get the best portion. </li></ul><ul><li>Never let the grant be the base </li></ul><ul><li>for your financial set up.   </li></ul>
  49. 49. Guaranty to get eggs, fry or fingerlings and guaranty to sell fish For many species there are eggs or fry or fingerlings all year round available. Packing and shipping in a sophisticated way to places all over the world.   If you produce a good quality fish on regular base in an area where there is a market or even better a niche market there is no problem to sell your fish.
  50. 50. Vacination of salmon fingerlings
  51. 51. Cobia fingerling delivery
  52. 52. Fingerling packing for transport
  53. 53. Arrival of fingerlings
  54. 54. Release of fingerlings
  55. 55. Start a farm by buying eggs, fry or fingerlings or buy an average stock To start from zero or buy a stock often depends on the capital men can spend.   When there is financially no objection: Start with eggs, fry or fingerlings especially when you selected a fast growing fish.   Anyway; always go for “new fish”; You never know what you get when you buy bigger older fish.
  56. 56. Keep your farm free of diseases or at least keep the risks as low as possible Buy eggs, fry or fingerlings from good reliable suppliers.   Use normal protection rules that people can follow and are willing to follow. Too many protections with foot baths, booths, shoe covers, hand cleanings, jackets, caps et cetera are often overdone.
  57. 57. <ul><li>For eventual visitors a simple sign: </li></ul><ul><li>“ No hands in the water and no touching”. </li></ul><ul><li>  </li></ul><ul><li>Off course it shall depend on the lay-out of </li></ul><ul><li>a farm. When you need to walk on a grit </li></ul><ul><li>above the tanks you need more protection </li></ul><ul><li>than when you walk on a concrete floor. </li></ul><ul><li>Employees will know the rules very well. </li></ul><ul><li>Each system must have it’s own working </li></ul><ul><li>equipment and a good regime for cleaning </li></ul><ul><li>and disinfections of working equipment.   </li></ul>
  58. 58. Differences between designs with different species and in fresh water or salt water Besides the right material choices, there are no major differences.   There is a basic design for a Hesy system with some loops for better water treatment and for waste water treatment. It often depends on the species and on availability of the right and enough water.
  59. 59. <ul><li>Some fish can be farmed in “dirty” water </li></ul><ul><li>but for salmon and in hatcheries we need </li></ul><ul><li>water as clean and clear as possible. </li></ul><ul><li>  </li></ul><ul><li>In a salt water system we include a protein </li></ul><ul><li>skimmer eventually with ozone dosing, but </li></ul><ul><li>HESY is not so keen to use ozone. </li></ul><ul><li>  </li></ul><ul><li>When possible we rinse the mechanical </li></ul><ul><li>filter with fresh water so the waste water </li></ul><ul><li>will be more or less fresh water. </li></ul>
  60. 60. Flow schema and impressions <ul><li>In the next pictures we give you an </li></ul><ul><li>overview of the water flows in a RAS </li></ul><ul><li>and some architectual impressions of </li></ul><ul><li>HESY systems. </li></ul>

  70. 70. Water consumption and waste discharges. (Discharge equivalents). This is an example of a waste water test in a 300 tonnes fish farm at full production: Process water 50.000 m3 per annum. C.O.D. 46 mg/l KJ-N 9 mg/l Waste Emission 79,7 (Inhabitant eq).  
  71. 71. <ul><li>This is an example of a sludge test in a </li></ul><ul><li>300 tonnes fish farm at full production: </li></ul><ul><li>Grams dry matter per kg 65.0 </li></ul><ul><li>Grams raw Ash (dust) per kg 19.0 </li></ul><ul><li>Grams organic matter per kg 46.0 </li></ul><ul><li>Gram Nitrogen N per kg 4.5 </li></ul><ul><li>C/N quotient (Carbon-Nitrogen ratio) 5.0 </li></ul>
  72. 72. Grams Nitrogen Ammonia N-NH3 per kg 1.0 Grams Nitrogen-organics per kg 3.5 Grams Phosphorus P2O5 per kg 5.8 Grams Kali K2O per kg 0.4 Grams Magnesium MgO per kg < 0.7 Grams Natrium Na2O per kg 0.9 A test in a farm before and after the installation of a de-nitrificate and de-phosphate unit: Before filtration After filtration C.O.D. 1.400 mg/l 67 mg/l S.S. 752 mg/l 63 mg/l B.O.D. 320 mg/l 17 mg/l Phosphate 45 mg/l 0,4 mg/l
  73. 73. Less water consumption when we use de-nitrification and de-phosphation Quantity of new water and waste water can be less, as we accomplished in a practical situation in a standard system. With de-nitrification and de-phosphation we can count with less than 30% of the normally used 250 litre per kilogram feed.
  74. 74. <ul><li>100% re-circulation. </li></ul><ul><li>A combination of fish farming and </li></ul><ul><li>Agriculture or aquaponics can lead to </li></ul><ul><li>almost 100% recirculation.  </li></ul><ul><li>With extra filtration of the “waste water” the </li></ul><ul><li>discharge of water can be limited to less </li></ul><ul><li>Than 1% of the water volume or 5 liter per </li></ul><ul><li>kilogram of feed. </li></ul>
  75. 75. Aqua ponics and Tilapia
  76. 77. Energy consumption in a fish farm In a system with all loops - for example a pike perch farm or an eel farm - without energy to produce oxygen it we need ± 7 kW electrical energy per kilogram produced fish. For Oxygen supplied by a generator we calculate ± 0.7 kW per kg production. Average we calculate with 0.7 kg O2 per kilogram production.  
  77. 78. <ul><li>When we install a system according the </li></ul><ul><li>Bleu Label design we can run a system on </li></ul><ul><li>± 60% of these electricity costs. </li></ul><ul><li>We can bring the filter system under level </li></ul><ul><li>so the main flows will be on gravity, in that </li></ul><ul><li>case only one pump is required. </li></ul><ul><li>We use moving bed filters for less pumping </li></ul><ul><li>but more aeration will be required. </li></ul><ul><li>Sometimes we simply must accept higher </li></ul><ul><li>energy costs. </li></ul>
