Panaeus monodon (PL45) were adapted to the culture condition
for 30 days period and nutrient removal at 60 days was
observed in the recirculation system (Experiment 1). The
maximum ammoniumconcentration ranged between 1.8 and
2.2 g m3 as shown in Fig. 4. After fourteen days, the mean of
ammonium concentration decreased to 0.5 g m3 and
1.2 g m3 in treatment integrated with G. edulis and U. lactuca,
respectively. Both species showed significant nutrient
