Chemical use in shrimp ponds
    The use of drugs and chemicals in shrimp ponds is a key issue it determines the survival of shrimp. If used improperly sizes, dosage will lead to unforeseen consequences. Here are the basic measures guided famers in part using drugs and chemicals to bring high results in shrimp ponds.
I.How to use drugs, medications:
 There are three methods of drug use in aquaculture.
         1. Bath method:
This method is often used to prevent or treat the disease outside the body of the shrimp
( bearing, body, spare set).
a. Bathing in a short time.
b. Bath for a long time.
c. Bathing in the average duration
       2. Mixed  drugs in food:
Mix the medicine into the feed for shrimp to eat, how often are used in the prevention and treatment od diseases of the body such as intestinal infectious diseases ( diseases classified white), liver disease.....
       3. Injection method:
In one little shrimp how to use that shot often used to bathe in a long time and mixing medicines into foods.
II / The units used to calculate the amount of drug use:
1. Ppm (part per million) ppm:
1 ppm is equivalent to:
- 1mg in 1 liter of water
-  1gr of 1m3
-  1ml of 1m3
-   1cc of 1m3
2. Percent (per cent)%:
    * 1% is equivalent to:
   - 10g in 1 liter
    - 10 kg in 1 tonne
3. Dose mixed into food based on:
  * The amount of food that shrimp use.
Total drug dose = use x number of pounds (or grams of food).
Example : Using  a dose of Vitamin C with 5- 10g/ kg food.
(This method is often used in shrimp farming, shrimp feed because of eating very easily calculated).
Shrimp body weight
Total drug doses used x = body weight.
Example : Mixing antibiotics with 30-50mg dose to 1 gram or 1 kg of body weight of shrimp.
   (This rarely used in shrimp farming)
III / problem diagnosis and treatment:
Person in charge of technical and shrimp neighbor to diagnose a relatively precise cause of the disease, drugs and chemicals used appropriately for each type of disease and rearing environment.
1. Treatment outside the room:
The disease caused by parasites: wide (due to protozoa, zoothanium), mushrooms, dried shrimp molting ... making, reduced food and weakened the bath method.
Eg prevention "extensive" use Formalan 60cc-100cc/m3.
2. Treatment inside the room:
Infectious diseases: diseases classified white, black sport, infection ( off beards, broken tail...)
We often use antibiotics to Enfloxin 3-5g/kg food for shrimp feed
3. The method of calculating the amount of drugs and chemicals into the water:
In addition to disease diagnosis, drug use, the farmers need to be calculated fairly accurately for the amount of drug in the pond.
 * The amount of drugs brought into the pond is calculated as follows:
     + The volume of water:
Water volume = area x depth of pond water
Usage Sterilization products VICATO pond environment improvement
 In the case of shrimp, fish disease:
Usage: Drop all around the lake who sterilized, used within 02 consecutive days, if ill use 03 consecutive days.
 In the case of preventative care for shrimp and fish:
      Dose :0,2-0, 3g/m3 water
Usage: Drop disifection members around the lake, about 10- 15 days will be used once effective disease prevention is very good.
