Advanced Aquaculture of Carps and Tilapia – Ponds and Cages Kevin Fitzsimmons, John Woiwode, R.S.N. JanjuaASA SoyPak Rawalpindi, Punjab, Pakistan 19 March 2012
Carp and Tilapia • Carps are most important farmed food fish and tilapia are second. • Global demand, variety of production systems and geographic regions, some vertically integrated • Environmentally sustainable – “Green Aquaculture” (no fish meal required in the diet, no antibiotics, many farms use effluents for crops)
Subsistence and Export Commodity • Tilapia is unique in its role as a small livestock animal grown by subsistence farmers in developing countries around the world….. • And • It is widely grown and exported to high value markets to be served in expensive restaurants and grocery stores • Commodity or specialty crop - BOTH, like chicken
US Tilapia consumption (imports and domestic)368,295 mt of live weight (equivalent) – 2006437,000 mt of live weight (equivalent) - 2007453,264 mt of live weight (equivalent) – 2008465,953 mt of live weight (equivalent – 2009)579,443 mt of live weight (equivalent – 2010)
Carp and tilapia in ponds • Extensive ponds
Multiple small cages Irrigation Reservoir, Arizona Taal Lake, Philippines Paulo Afonso Reservoir, Brasil
Other small cages Nile Delta, Egypt Shrimp Pond, Thailand Shrimp Pond, Philippines All tilapia farms have dogs, even cage farms
Integration of aquaculture and agriculture • Water pH reduced from 8.3 to 8.0 • Added 19.7 kg/ha N to 45 kg/ha used in standard fertilization schedule of cotton.
Results - Integration of aquaculture and agriculture • Contributed 2.6 kg/ha P to cotton crop.
Plant height with Fish Effluent, Standard Fertilizer and Well Water
Extruders • Floating feeds • Feed mixes with steam in barrel of extruder • Cooks ingredients, improves palatability • Gelatinizes starches • Steam expansion and auger forces feed out of barrel with rapid expansion. • Traps air in pellet, allows to float
Conclusions • Tilapia are omnivores • But eating anything will not make you grow fast and strong • Tilapia need balanced nutrition for rapid growth just like human children
