Use of shrimp probiotics in farming
Immune system:
In relation to farmed shrimp, bacterial diseases are
considered as the largest cause of mortality in larvae. The administration of a
mixture of bacteria (Bacillus spp. and Vibrio spp.) positively influenced on
survival and had protective effect against Vibrio harveyi and the white spot
syndrome virus (WSSV). This result was
due to stimulation of the immune system, by increasing phagocytosis and
antibacterial activity.
The administration of a commercial probiotic for the larvae
of Marsupenaeus japonicus resulted in increased survival (97%) being
significantly higher than the control treatment. Thus, the use of Bacillus
coagulans SC8168 as probiotic for postlarvae of Litopenaeus vannamei resulted
in higher survival of animals .
In a study with tiger shrimp (Penaeus monodon), the
inoculation of Bacillus S11, a saprophyte strain, resulted in higher survival
of post larvae challenged by a luminescent pathogenic bacterial culture.
Bacillus subtilis and Lactobacillus plantarum for
Litopenaeus vannamei , Pediococcus acidilactici to Litopenaeus stylirostris and
Bacillus NL110 and Vibrio NE17 for Macrobrachium rosenberguii also proved
effective in improving the immune system of these animals.
Performance:
Lin and colleagues used Bacillus spp. in the diet of
Litopenaeus vannamei enhancing digestibility rates of the feed. Ziaei-Nejad and
colleagues added the probiotic Bacillus spp. in the farming of Fenneropenaeus
indicus larvae and observed survival increase, and also an increase in the
activities of lipase, protease and amylase enzymes in the digestive tract of
shrimps.
Several studies have shown that the bacteria of the genus
Bacillus spp. secrete exoenzymes (proteases, lipases and carbohydrases) that
can help improve digestion and nutrient absorption increase, resulting in
better use of food and animal growth.
AquaPro: |
Aquapro is the biosecurity
product that must be added just 3 days prior to introducing the PL (Post
larvae).
- This application improves biosecurity in the PL stages, and
- Eliminates the undesirable organisms for healthy/dynamic PL.
3 days of AP treatment prior to
PL introduction is part of BAP(Best Aqua culture practices) to make the pond
water secure by controlling bacterial pathogens particularly Vibrio sp. It
supports low BOD levels and healthy plankton/ supports bio floc growth. If the
product is used on a regular basis Animal health is assured if followed as per
protocol.
AquaPro is a probiotic formulation designed to maintain a healthy environment. These microbial strains are known to produce several antimicrobial compounds capable of inhibiting the proliferation of pathogenic bacteria in shrimp and aquatic system.
Aquapro regulates or enhances the microbial environment, allows the establishment of healthy gastro intestinal micro flora improve feed conversion ratio and increase weight through biological availability of feeds. Improves resistance to stress, disease and lowers mortality rates. Natural treatment to sustainable shrimp farming.
AQUAPRO have improved the diatoms in the ponds and maintained the natural source of food
