EFFICACY
TEST OF NS SERIES SUPER SPO in THAILAND (Eastern Area - 1991)
OBJECTIVES
To determine the efficacy and effects of NS Series Super SPO on the reduction of wastes, water quality,
survival rate and production of Black Tiger Shrimp Ponds (P. monodon).
METHODOLOGY
This experiment was conducted on 4 ponds, divided onto 2 pairs of tests as follows:
| lnoculated Pond I &II (NS Series Super
SPO) |
Control Pond I & II |
| Applied product weekly |
No application |
| Pond area - 5 Rai |
Pond area - 5 Rai |
| Stocking density - 300,000 pcs PL1S or 37.5/M2 |
Stocking density - 300,000 pcs. PL1s 37.5/M2 |
| Source of PL - Wang Kaew Farm |
Source of PL - Wang Kaew Farm |
| Stocking date - July 30, 1991 |
Stocking date - July 31,1991 |
All four ponds ( 2 inoculated and 2 control) were harvested on December 23, 1991, and the results are as follows:

*This actual field trial was undertaken by T. C. Union Agrotech Inc.,
the Thailand distributor of NS Series Super SPO ( PURA) in 1991.
CONCLUSION
The application of NS Series Super SPO in Black Tiger Shrimp pond reduces waste,
increases survival rates, improved feed conversion ratio
(FCR) and increased the total profit in the inoculated ponds compared to control ponds.
