NS SPO

For Grow-Out

One major problem often encountered in prawn farming is pond bottom pollution. The very slow natural degradation process undertaken by naturally occurring microbial cultures cannot cope up with the rate and bulk of waste production. Degradation of the aquaculture ecosystem from the rapid accumulation of pollutants can have disastrous one-way downhill effect. Ammonia, hydrogen sulfide, nitrites, acidity and D.O. depletion are the major contributors to the problem.

NS Series Super SPO is the result of trying to find a solution to these problems for a better harvest. NS Series Super SPO is a scientifically blended concentration of selected, adapted, cultured and improved bacterial strains grown to higher concentration for better survival, faster exponential increase in bacterial population and enzyme production. It is grown on cereal and mineral substrate plus enzymes and special buffers that are designed to degrade organic wastes faster and more efficiently. Also, dominance of good bacterial strains over the weaker and less efficient strains are achieved at a faster rate.

CHARACTERISTIC:

pH	pH - 6.5 to 8.5
Appearance	Free flowing tan powder
Odor	Yeast-like
Moisture content	15%
Bulk density	0.50 to 0.61 g/cm³
Standard packaging	25 kg. drums and 1 kg. plastic bottles

OPTIMUM CONDITIONS:

Bacteria and enzymes present in NS Series Super SPO perform within a pH range of 3.5 to 9.5 with the optimum near pH 7.5. Bacteria remains 100% efficient in temperature as high as 65 ºC. However, at 80 º C, the efficiency diminishes by about 15%.

FEATURES:

	Removal of H₂S, NH₃ and N0₂
	Breakdown of organic and fecal waste
	Increases nutrient availability for plankton growth
	Reduction of bottom sludge
	Stimulation of growth rates of prawns
	Prevention of diseases
	Increases survival rate
	Minimizes pond bottom acidity
	Prevention of D.O. depletion
	Maintenance of good water quality
	Prevents drastic biochemical & nutritional changes that upset the metabolism of prawns
	Increases ABW, improves FCR
	Controls suspended solids due to high organic loading
	Decreases power consumption due to less water change.

Note:

Dosage application is independent of percent water change. If the schedule of water change and NS Series Super SPO application coincides, apply product after water change.

Simultaneous application of organic or inorganic fertilizers and NS Series Super SPO is not advisable since it may cause over-blooming specially if pond bottom is deteriorated because of high organic matter content. However, if pond technician is well versed in monitoring water quality, you may do so.

In case of over-blooming, change 5-10% water daily until plankton bloom stabilizes.
Dosage may increase or decrease depending on the quality of. water source.

For tidal dependent farms, apply NS Series Super SPO when water change is possible. Do not forget to add the dosage of the previous week.

STORAGE & HANDLING:

Store in cool dry place. Keep out of direct sunlight. Avoid direct inhalation. Wash hands with warm after handling.

DOSAGES:

Dosage level varies widely with each application based on the number of days of culture (DOC), stocking density (SO) and actual pond conditions. The following is the recommended dosage application.

APPLICATION PROCEDURE:

Activate NS Series Super SPO by soaking one (1) gram of dried cultures in 200 milliliters of pond water (or one kilogram of NS Series Super SPO in 5 gallons of pond water). Soak for four (4) hours with occasional stirring before application.
Apply slurry at highest pond level and along pond perimeter.
The best time for application is from 4:00 p.m. onwards.
Continue running aerators as the usual practice.

REMEDIAL APPLICATION RATES

REMEDIAL APPLICATION RATES (RAR) for NS SERIES SUPER SPO on ponds with stocks from DOC 40 upwards:

The following recommended dosages for the first application must be applied to ponds which were not treated with NS Series Super SPO upon stocking and with DOC of 40 days upwards to build up the required biomass needed for effective degradation of organic wastes and metabolites that have accumulated in the ponds.

DOC	Area = 1.0HA	Area = 1.0 HA	Area = 1.0 HA	Area = 1.0 HA	Area = 1 HA
	Depth = 1 m	Depth 1 m	Depth = 1 m	Depth = 1 m	Depth = 1 m
	SD 1 - 4/M²	SD 5 - 9/M²	SD 10 - 20/M²	SD 21 - 30/M²	SD 31 & up
40 - 60 days	1.25 kgs.	2.50 kgs	2.50 kgs	5.00 kgs.	5.00 kgs.
61 - 80 days	2.50 kgs	5.00 kgs	5.00 kgs	7.50 kgs	7.50 kgs
81 - 100 days	3.75 kgs	6.25 kgs	7.50 kgs	10.00 kgs	12.50 kgs
101 - harvest	5.00 kgs	7.50 kgs	10.00 kgs	12.50 kgs	15.00 kgs

Note:

For the second succeeding applications, the standard Recommended Dosage application may now be used after the remedial dosage has been applied. In some cases, accumulation of organic wastes in the pond bottom may already be high. The application of RAR may cause D.O. depletion during the night. Be sure to provide adequate aeration to avoid depletion at least 3 - 5 days after RAR.

The second thing to watch out for after RAR is over blooming of planktons. This is due to the product going to work immediately on the heavy accumulated organic wastes. This situation can be corrected by minimal daily water change of 5 - 10% until the plankton growth is stabilized (usually 3 - 5 days after over blooming Then the regular recommended dosage may now be scheduled. For those depending on tidal water change, the RAR should be applied 4 - 5 days before high tide to have ready water supply for _ changing in case of over bloom. This over blooming condition is critical and should be corrected at once to avoid plankton collapse.

Upon the release of nitrogenous compounds broken down by microbial decomposition, floating or rising of dense lab-lab (algae) may occur. Simply scoop out manually before they settle again and pollute the pond bottom.

Formation of scum is expected upon the use of the product. Be sure to scoop off scum before they settle to the pond bottom. Monitoring of this should be done daily.
