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.
