Furthermore, macroalgae integrated culture during 120
days of shrimp growth period (Experiment 2, Fig. 4), exhibited
the similar trend of nutrient removal and the differences now
was the initial concentration of ammonium was in the range
of 5.5e6.5 gm3. This value is three times higher than it was in
Experiment 1. G. edulis illustrated 60% reduction (F ¼ 235.1,
P < 0.01) and U. lactuca was 50% (F ¼ 44.3, P < 0.01). Similarly,
both these macroalgae species significantly absorbs ammonium
as in Experiment 1. Without macroalgae, control tank,
has no significant nutrient removal and recorded F probability
value of 13.44 (P > 0.05).
