dc.description.abstractThis research was carried out to study the effects of thyroxine hormone immersion treatments, administration at a single dose, on the late development stages ( stage 8 onward) of Macrobrachium rosenbergii larvae for a period of twenty-one day. Twenty days old larvae (stage 8) were immersed in thyroxine hormone solution at concentrations of0.001, 0.01, 0.1, 1.0 ppm and control (0.00 ppm), each with three replicate. The larvae were reared in 2 liter transparent aquarium tank at the density of 40 larvae per tank (20 larvae.liter-\ They were fed Artemia nauplii twice daily. At the termination of the experiment, 0.1 ppm treatment showed highest post larvae production (13.5 PL.lite(1 ), followed by 0.01 ppm (10.5 PL.liter-\ 0.00lppm and 1.0 ppm (10 PL.liter-1 respectively). Post larvae production for control was 4.5 PL.liter-1 • The highest growth (in term of mean development stage) and dry weight was achieved for treatment 1.0 ppm whereas treatment 0.1 ppm resulted the highest survival.en_US
