Site Description
Oppenheimer Biotechnology, Inc. is
working with the
Philippine company Envirogenics Phil., Inc. to evaluate the use
of our products to enhance production in shrimp pond culture.
Shrimp are a bottom feeding crustacea with coprolytic behavior.
Penaeus monodon is the species of shrimp that is predominantly cultured
in the Philippines.
- Project Description
Preliminary controlled tests on 2 - 5 acre ponds have been conducted.
The water in the ponds is a mixture of fresh and sea water supplied by an open
bay and river.-
- The
application of Oppenheimer Formula I to sediments in the drained tanks and to
the water has been shown to double the normal production in the same time
period. There is also evidence that the microbes may reduce the mortality
caused by other competing microorganisms and to control algae.
The experiments are being continued in a series of controlled ponds designed to
produced information on nutrient regulation, growth rate, mortality, stocking
density and microbial application rates. All ponds are being monitored
continually on a daily or weekly basis for temperature, pH, oxygen, ammonia,
nitrates, phosphate, algae, vibrios, growth rate, and mortality.

Note:
The Oppenheimer Formula I has been successfully used in
chicken farms to recycle chicken waste by adding nitrogen from
ammonia fixation. Such recycling reduces ammonia and it’s
effect on feeding and ulcers, reduces the amount of food
required, and increases growth rate. These data stimulated the
tests with shrimp culture.
