3	Paddlefish Project 2006 3, 0.2 hectare ponds were stocked in two counties. 25-30 thousand pL shrimp/ha on May 21 and June 1, 2006 988 paddlefish/ha June 8, 2006
4	Pond Management No aeration Ponds fertilized: alfalfa + 0:46:0 Shrimp fed no more than 22.5 kg/ha sinking catfish pellets daily Paddlefish grazed plankton

26	Paddlefish Stockers Polyculture to produce paddlefish stockers (avg. wt. = 346 g) Potential bonus crop for low-input shrimp ponds Increase pond yields without increasing feed & fertilizer inputs
