  1. Catfish Production in Zimbabwe By Rory Mackie

  2. Overview • Aquaculture Industry Overview • The African Sharp-tooth Catfish • Options for Zimbabwe • Mr Muramba • Conclusion

  3. Aquaculture: A Global Perspective • What is Aquaculture? • Aquaculture is the rearing of aquatic organisms in captivity • Give a man a fish and you feed him for a day, Teach a man to fish and you feed him...... Only until the wild stock lasts, Teach a man to grow fish and you feed him for a lifetime (Aquaculture Innovations)

  4. Aquaculture Growth • 1993 – 17.8 Million tons produced • 2006- 51.62 Million tons • Average growth of 8% p.a. • Nigerian aquaculture produced 751 000 tonnes of fish of which: • 80,000 tonnes were African Sharp tooth Catfish • Doubles every 3 years • Zimbabwean Aquaculture produced 3 to 4,000 tonnes, Bream only (Lake Harvest) • 10,000 Tonnes of wild fish production (Kapenta) • Figures: FAO 2009 and Aquaculture Zimbabwe Trust

  5. Why Aquaculture? • Dwindling wild fish catches • Increased demand for fish • Growing world population • Increased expendable income • Greater demand for healthy white meat

  6. The African Sharptooth Catfish(Clarias Gariepinus) • Catfish, Muramba or Barble

  7. Advantages • The ULTIMATE aquaculture species • Air breather – Can obtain o2 from the atmosphere • Fast Growth - 6 Months to 1kg • High stocking density – Up to 750kg/m3 in RAS • Disease resistant – High tolerance to poor water quality • High fecundity – 50,000 eggs/kg of female • High dress out percentages – Over 50% • Low labour demand, low water demand • Storage – Can survive out of water for several days

  8. Options for Rural Zimbabweans Earth Ponds

  9. Advantages • Cheap - Easy to build, minimal equipment required • Low level of expertise – Minimal management • Natural heating – Sun is for free • Low risk – As compared to other aquaculture systems • 15 Tons per Hectare * • 150kg from a 10m x 10m pond (Bream 20 to 30kg’s) • Feeding with a nutritional compete sinking pellet • F.C.R of 1.8* • Cost per Kg of Protein $1.44 (Cost of Feed 80c/Kg ) • Fish can be dried and stored *Manual for the Commercial Pond Production of African Catfish in Uganda USAID and Fisheries Investment for Sustainable Harvest

  10. Mr Muramba • Recirculating Air System • Commercial production of Catfish fingerlings • Commercial production of Catfish for sale as a food fish • 15mx4m Insulated building • 2 Labourers • 1o Tonnes a month • 100,000 Fingerlings a month

  11. Conclusion • Test Case • Results from Zimbabwe • Education • Courses • Training
