On-Farm Demonstration in Chonburi Province, 2002
Shrimp Study - Growth Graph
| Comments: Test weighings of shrimp at 60, 70 and 80 days showed
a marked difference in the growth rates of test vs control. The
study director then started feeding AZOMITE feed to the control shrimp. After day 80 the graph shows the growth
rate of the control shrimp (now eating AZOMITE feed) was parallel to the test shrimp on AZOMITE from start. |

Black Tiger Shrimp
( with and without AZOMITE® )
- Larval shrimp were grown until they reached PL 15 stage, and
then 6 ponds, average surface area of 3,667 M2/HA per pond,
were seeded with the PL 15 for a cultivation study. 3 Ponds
served as Controls and 3 Ponds were treated with AZOMITE? (Trial)
- Cultivation was done for 120 days, and both groups received
identical feeds (GROBEST)
- Shrimp were seeded at a density of 30 PL/M2
- The soil in Trial ponds was treated with AZOMITE? at the rate
of 200 Kg/HA
- Dissolved Oxygen, pH, Phytoplankton & Zooplankton Populations,
Growth Rate and Survival were measured

( with and without AZOMITE® )
Overall Conclusion about Black
Tiger Shrimp Study
- AZOMITE® improved Growth
Rate (17.5%) and Survival (35%)
- Zooplankton and Phytoplankton levels were improved substantially
by treatment
- Dissolved oxygen was improved, but the amount of improvement
varied from morning to afternoon, and only insignificant changes
in pH were noted in treated ponds
- Overall, the economics of treating bottom
soil of ponds is highly favored.
