| To investigate the water quality and aquatic production in an aquaponic system, the aquatic vegetable
Ipomoea aquatic was planted on floating beds in outdoor shrimp ponds. Results showed that water quality indices including
water transparency, TN, TP, CODMn, chlorophyll-a and microbial biomass were more stable than those in control. The fresh
weight of I. aquatic was 200.8 (3.3) kg, the removal percentages of TN and TP were 3.18% and 1.79%, respectively. The
shrimp production and the rate of removal nitrogen and phosphorus in planded pond were slightly higher than those in
control ponds. The results suggested that the water quality could be improved effectively and a higher shrimp density could
be stocked in the ponds planted I. aquatic. |
