Intensive Shrimp Production
  • High stocking densities:  40-59 thousand pL/ha
  • Substrate
  • Pond-side electricity
  • Aeration

5
Reduce Inputs
  • Low stocking density
  • No substrate
  • No aeration
  • Daily feeding capped at 22-28 kg/ha
6
 
7
Demonstrations 2002 & 2003
  • Produced 365 – 449 kg/ha
  • Max daily feed @ 28 kg/ha
  • Stocked 20 K – 25 K pLs/ha
  • 55-64 % survival



8
Lessons from 2002 & 2003
  • Larger shrimp = more $ & kg/ha
  • Use 60-day pL – 0.3 g or greater
  • Stock more shrimp & feed less
  • Use inorganic fertilizer with alfalfa

Demonstrations
2004 & 2005
  • Cap daily feed at 22.4 kg/ha
  • Fertilize with alfalfa and triple super-phosphate (0:46:0) before stocking shrimp
  • Stock 24,700 pL/ha
