Abstract:
Twenty one day old larvae of Macrobrachium rosenbergii (stage 8) were treated with
different concentration of hydrocortisone hormone by immersion (0.00lppm, 0.0lppm,
0.l ppm, lppm). To scan for its influence on larval growth and metamorphosis to post -
larvae (PL). The hormone was administered only once (at the beginning the experiment),
during the experiment, which was conducted for 21 days. The larvae were stocked at
density of 20 larvae / liter, reared in small plastic aquarium 2 liter at brackish water
(12ppt) (40 larvae/ tank).
