Spawns during cool periods in
summer and sometimes fall, eggs hatch in 5-6 days. Females lay from 200-500 eggs per
spawn, spawn repeatedly during spawning season.Two methods are used to produce fry. The
first is the wild or free-spawning method which 500-2,000 broodstock are stocked into
ponds. Egg hatching and growing of yound to marketable size occur in the same pond. The
second methodbis the fry transfer method. In this method, 20,000-25,000 broodstock are
stocked into ponds in a ratio of five females per male. Fry produced in either method are
trapped and counted then transferred to rearing ponds. In either method, rocks, tile,
bricks, or boards are placed into ponds to provide spawning sites. |
