Poor water quality is a major stress to all aquatic animals. Stresses
are additive and increase the susceptibility of the animals to disease
while decreasing their growth rate and feed conversion efficiency. To
say that antibiotics and bactericidal products are essential is to admit
that adequate water quality is not being maintained. It is much easier
to prevent diseases than to try to cure them. Disinfectants may help avoid
some diseases, but they treat only symptoms and not the cause of the problems.
The Bacta-Pur System can help improve water quality, reduce stress to
the animals, improve growth and feed conversion and reduce the need for
and expenses of drugs.
The beneficial microorganisms
in Bacta-Pur biotechnologies convert wastes in ponds into bacterial biomass,
producing food for higher life forms including fishes.
Experimental work with fish has shown that use of Bacta-Pur increased
production by over 37% (Ehrlich et al. 1991; A diagnostic and
ecological approach to the purification of sewage, toxic substances
and water bodies; IN: Ecological Engineering for Waste Water Treatment,
Proceedings (C. Etnier & B. Guterstam eds) Bokskogen, Box
7048, S-402-31, Gothenburg, Sweden. pp. 95-109). Similar benefits
of bacterial augmentation have been found for growth and survival
of prawn and crab larvae (Maeda & Nogami, 1989; Some aspects
of the biocontrolling method in aquaculture. IN: Current Topics
in Marine Biotechnology (S. Miyachi, I. Karube & Y. Ishida,
eds), Japan. Soc. Mar. Biotechnol., Tokyo, pp. 395-398). These
authors also showed that regular additions of beneficial bacteria
reduced pathogens (e.g. Vibrio spp.) in the culture water.

Drugs cannot improve
growth and feed conversion efficiency nor can they be used indefinitely
to compensate for declining water quality. If proper attention is not
paid to the maintenance of good water quality, decreasing returns from
fish ponds are inevitable.
The Bacta-Pur biotechnological
system can improve water quality in ponds while converting wastes into
natural food.
Regular
use of Bacta-Pur has also been shown to reduce nitrogen and phosphorus
in trout pond effluents.

Treatment
with the Bacta-Pur System
Bacta-Pur
biotechnologies are highly concentrated; the guaranteed minimal
cell count exceeds 10x11 cells/mL. Compare this to any other brand,
and you will appreciate the concentration of Bacta-Pur products.
Small regular doses are very effective.
Ponds are
treated with a combination of two biotechnologies (Bacta-Pur
N-3000 and Bacta-Pur XLG)
and Bacta-Pur CARRIER 1, which transports bacteria through the water
column to the sediments. The two biotechnologies work together to
produce clearer water, control ammonia and nitrite, remove organic
sediments and to convert pollutants into food for invertebrates
and fishes.
One L Bacta-Pur
XLG & 2 L Bacta-Pur N3000 / 1,000,000 L pond water (1) / week.
The application technique consists of preactivating Bacta-Pur XLG
for 24 hours; Bacta-Pur ACTIVATORs 1&2 with precise instructions
are attached to each bottle. The weekly dose of Bacta-Pur is mixed
with 1 kg of Bacta-Pur CARRIER 1(2) per 10 litres of Bacta-Purand
stirred for 30 minutes. The mixture is then diluted with 10-100
X the volume of pond water and is sprayed or splashed over the surface
of the pond.
Raceways are
treated with Bacta-Pur N3000 to control ammonia and nitrite. Phosphorus
reduction in effluents has also been reported.
One half litre
of Bacta-Pur N3000 is continuously added to each 1,000 m3 (260,000
gal US) of incoming water. Automatic on-site growth and continuous
injection of nitrifiers is most easily accomplished with a Bacta-Pur
Bactivator.
Settling
Ponds are treated with Bacta-Pur XLG to solubilize sludge and
remove soluble pollutants.
Four L Bacta-Pur
XLG / 1,000,000 L settling pond water(1) / week. The weekly dose
of Bacta-Pur XLG is preactivated, mixed with 1 kg of Bacta-Pur CARRIER
1(2) per 10 litres of Bacta-Pur and stirred for 30 minutes. The
mixture is then diluted with 10-100 X the volume of pond water and
is sprayed or splashed over the surface of the pond.

Calculate pond volume
by multiplying the averages of the length, the width, and the depth. 1m3
= 1000 L, 1ft3 = 28.3 L. Other useful conversion factors: 1 kg = 2.2 lb.;
1 L = 0.264 gal US.
An alternative to
the use of Bacta-Pur CARRIER 1, in small ponds, is to pump the diluted
mixture into the sediments or to simply pour the mixture down a pipe
the end of which is resting on the bottom. If the pipe is used the pipe
should be flushed with pond water before withdrawing it from the pond.
This will assure that the Bacta-Pur is released in the sediments.
