It is widely demonstrated that farmed sh, prawn and shrimp are
more susceptible to disease agents than their wild counterparts
due to the artificial conditions posed by intensive rearing. The
immune system of aquatic organisms, such as fish, prawn and
shrimp is continuously affected by periodic or unexpected
changes of their environment. Adverse environmental situations
may acutely or chronically stress the fish, prawn and shrimp
altering some of their biochemical parameters and suppressing
their innate and adaptive immune responses. Nonspecific
defense mechanisms play an important role at all stages of
infection. Fish, prawn and shrimp particularly, depend more
heavily on these non-specific mechanisms than do mammals.
Hence, there has been increasing interest in the modulation of
the non-specific immune system of fish, prawn and shrimp as
both a treatment and prophylactic measure against disease.
When infectious outbreaks appear they may be fought by means
of chemotherapeutants, vaccines or immunostimulants.
More recently, the administration of probiotics to fish, prawn and
shrimp through the diet and to the pond has appeared as a very
promising control measure in fish, prawn and shrimp
farms.ProYeast is a novel probiotic formulation of Yeast and
Bacillus sp. to provide improved performance of commercially
important aquaculture species in aquaculture ponds.
Prime Yeast formulation providing Saccharomyces cerevisiae
and Bacillus sp. is well designed for maintenance and balanced
growth rate of Shrimp, Prawn and Fish. Prime Yeast has potential
benefits to improve the non-specific immune response which
reflected on the stimulation of macrophage cells and increasing
their phagocytic activity. Prime Yeast could provide healthy and
safe fish production from aquaculture replacing antibiotics for
both fish and fish consumers.
