| Abstract | An experiment was conducted on integrated intensive culture of shrimp (Penaeus monodon) with AquaMats™ and Nile tilapia (Oreochromis niloticus) in a closed low salinity system to compare their effects on water quality and the growth and survival rate of shrimp. The concrete tanks of 5-m3 with saline water of 5ppt were used for the experiment for a period of 14 weeks at the Asian Institute of Technology campus. Postlarvae (PL15) with an average size of 0.025g was stocked at a density of 50 PL1s/m3 and fed with commercial pelleted feed containing the protein, fat, moisture and ash components of 36%, 9%, 12% and 4%, respectively. The buoyant ribbon-like AquaMats™ (Im high, 2 m long) was anchored to tank bottom. Sex reversed Nile tilapia with an average length of 3cm, weight of 0.63-0.69g were stocked at a density of 30fish/lm3 in a net cage which was suspended in the center of tank without supplemental feed. The experimental treatments were: I) shrimp only as control, 2) shrimp with AquaMats™ and 3) shrimp with tilapia. All treatments were conducted in triplicates. The water quality was slightly better with AquaMats™ treatment during the first two months. The shrimp survival rate of 30.5%, 31.67% and 38.0% was obtained in control, AquaMats TM and tilapia treatment, respectively and significant difference existed between tilapia treatment and control (p<0.05) but was not different between control and AquaMats™ treatment (p>0.05). The average of final weight was highest in AquaMats™ treatment (18.54±2.23g) followed by control (15.93±0.82g) and tilapia treatment (11.02±0.70g) and there was a significant difference among all treatments (p<0.05). FCR was recorded in AquaMats™ treatment (1.59) followed by tilapia (1.5) and control (1.49). and there was not significantly different (p>0.05). AquaMats™ can potentially serve as biofilter and absorbed nitrogen and phosphorus such as N02-N, N03-N, NH3-N and P04-P in ponds to improve the water quality. Tilapia, as phytoplankton feeder, not only maintained the stable water quality but also contributed to fish production |
