The application ratio for water applications are the same across the board, whether a fresh water pond or a stock pond. It is one part Activated EM•1® (AEM•1®) Microbial Inoculant per 10,000 parts water in the system. Frequency of application varies according to the type of fish grown and the type of system being used. Sometimes a weekly application is done, alternating EM5 with AEM•1® Microbial Inoculant. Some pond systems are used year-round and not drained while others are cleaned on a rotating yearly basis. Fertilizing of these ponds is done and AEM•1® Microbial Inoculant added. These are general guidelines that may be changed due to measurable parameters, such as ammonia concentrations, animal charge, organic material, oxygen level and water exchange. If you have a stock pond that needs treatment, please contact TeraGanix Services for assistance in developing a unique program for your situation.
WATER DILUTION AND AEM•1® APPLICATION ON RACEWAYS
The solution of AEM•1® to use on raceways is a 1:7,000 dilution divided by the days the shrimps stay in this place. For example, if the raceway has 70 TM (Metric Tons) and the shrimps are going to stay 25 days, the doses of the AEM•1®will be 1 pint (473 milliliters) per day. This quantity of AEM•1® will be diluted in 5 gallons (19.5 L) of water, to homogenize the application.
EM•1® BOKASHI APPLICATION THE POND SOIL
EM•1® Bokashi is applied to the pond to introduce beneficial microorganisms to the soil and second to nourish the soil with useful minerals for the growth of algae and phytoplankton that are the main feed for the shrimp on the first days in the pond. An added benefit is that the EM•1® Bokashi is a source of feed for the shrimp. Analysis had shown that EM•1® Bokashi has between 10-15% of protein, depending on the raw material used.
The quantity of the Bokashi depends on the materials used and is applied according the soil needs. Generally, the first dose of EM•1® Bokashi for shrimp farms is 528lbs per acre. This dose is reduced for the second cycle to 440lbs per acre, and from the third cycle on is stabilized at 375lbs per acre. Soils that have a good percentage of organic material (>2.5%) may not need a Bokashi application to the soil. A minimum application rate of 200lbs per acre is still recommended during the cycle.
During the summer the environmental conditions make the growth of phytoplankton or primary feed very difficult. We recommend the use of inorganic fertilizers like sodium meta silicate or ammonium nitrate when the conditions of the area do not show any positive changes.
BOKASHI APPLICATION TO THE POND WATER
Starting the second week after the post larvae stocking, start with bi-weekly applications of EM•1® Bokashi. When EM•1® Bokashi is applied shrimps are not fed with the extruded feed, and the applied doses is 20lbs per acre.
AEM•1® USE ON THE POND WATER
The first application of AEM•1® to the water is done when the water level is up to 50% of normal height. After that, apply weekly during the cycle. Apply by siphoning or dispersing to guarantee the product will be evenly distributed on the bottom and surface of the pond.
