AZOMITE™ Inclusion in Tilapia Feed Improves Their Growth Rates
Five Studies: Marine Science Institute and Fushou Feed Company of
Taiwan, University in Bangkok and Two On-Farm Shrimp Tests: in Chonburi,
Thailand and in VietNam.
Marine Science Institute
Objective of the Study:
Compare, in Tilapia Fry:
- Basal Diets (Control Group)
- Basal Diet plus (+) 1% AZOMITE™ (AZOMITE™ Group)
Procedures and Parameters
- Fish Used (Hybrid Tilapia): Oreochromis niloticus x O. aureus
- Initial Weight: 0.54 +/- 0.01 gram/fish
- 15 Fish/Aquarium
- 4 Aquaria/Treatment
- 8 Weeks Duration

Weight Gain, Feed Efficiency and Other Results in Tilapia
- Survival
- Control = 95%
- AZOMITE™ = 100%
- Feed Efficiency
- Control = 0.58 +/-0.18
- AZOMITE™ = 0.59 +/-0.1
- Protein Efficiency Ratio
- Control = 1.66 +/-0.04
- AZOMITE™ = 1.67 +/-0.17

Conclusions: Marine Science Inst.
- Body Weight Gain was statistically significantly increased by approximately
33% over 8 week period in presence of AZOMITE™.
- Survival Rates, Protein Efficiency Ratio, Proximate Composition
and Feed Efficiency were not impacted by AZOMITE™ .
- The economics of using AZOMITE™ to enhance weight gain in Tilapia is favored.
Tilapia and AZOMITE™: University in Bangkok
- Tilapia Fry, approximately 6.5 grams/fish initially.
- Three aquaria per test group.
- Identical number of fish/aquarium.
- Length and Weight measured on individual fish at Start and Approximate
One Month.

Field Demonstration in Taiwan
- Objective: Conduct small test at Max. Dose
- Test product at maximum level to see if there are any negative
effects
- Emphasize possibility of positive impact with high dosage
- Eliminate water quality as issue in test. Stretch across pond
to separate test groups.
Details of Taiwan Field Test
- 12,000 Tilapia Fry: .5 for Control and .5 for Test. Use one pond.
- Control and Test groups in same pond, separated by nets.
- Feed provided twice daily with automatic feeder.
- Test for four months.
Two Tests in Taiwan Overall Conclusion
- Tilapia fry that received 1% AZOMITE™ exhibited 40% better performance than Control group.
- Conducted 2nd test, using Control, 0.5% & 1.0% AZOMITE™ in feed.
- Establish reproducibility of 1st test result by replicating the
test units in 2nd test.
- Unusual and unreproduced work unacceptable by management.
- Now Including 0.5% to 1.0% AZOMITE™ in Feed for Cultivation of Fish.
Overall Conclusion for Three Separate Tilapia Tests
- AZOMITE™ reproducibly stimulates
growth of Tilapia: 36%, 40% & 45% in Taiwan and BKK studies
- Length was increased by as much as 32.5% in the Bangkok study
