Different roles of microorganisms in the shrimp pond system.

Hello everyone:
         Today we will see about how microorganisms plays an important role in managing the pond water quality. 

"Without microbes culture is nothing"

Different species of bacteria involves in degradation of organic matter, formation of flocs and maintaining the water quality.

The beneficial bacteria not only used to control vibrio but also doing important functions in degrading pond wastes, production of extracellular enzymes, antioxidants etc... 



In this regards, we will see about role of autotrophic bacteria in shrimp pond. 

Autotrophic bacteria:
     Autotrophic bacteria involves in photosynthesis and chemosynthesis. 
    They are using inorganic compounds as their energy source. 



  Autotrophic bacteria.. 
1. Photoautotrophic bacteria. 
2. Chemoautotrophic bacteria. 

Photoautotrophic bacteria:
   These bacteria are involves in photosynthesis in the presence or absence of oxygen. 

# The bacteria which involves in photosynthesis in the presence of oxygen then it is called aerobic photosynthetic bacteria. 
Ex: Cyanobacteria which involves in photosynthesis with the help of oxygen. 

#The bacteria which do not utilize oxygen as a acceptor then it is called anaerobic photosynthetic bacteria.
 They are mostly using sulfides and hydrogen as a acceptor. 

Green sulphur bacteria, purple sulphur bacteria, purple non sulphur bacteria. 

1. These green sulphur bacteria utilizes sulfide, hydrogen, ferrous iron as the source for breakdown. 
They are not able to produce energy when there is no sulfide in the pond environment. 
Another important fact is these bacteria can't able to grow heterotrophically. 

2. Purple sulphur bacteria also uses sulfides and hydrogen as the energy sources in the anaerobic conditions.

 This purple sulphur bacteria can able to grow heterotrophically. 

They have the capability of doing more photosynthetic activity in the pond. 

3. Purple non sulphur bacteria utilises organic compounds. 

These purple non sulfur bacteria is sensitive to hydrogen sulphides. 

They oxidize sulfur usually at lower level. 
But they can photoassimilate wide range of organic compounds presents in the pond system. 

In these regards, we can conclude that they need sunlight and chemical compounds for the effective functions in the pond environment except some species. 

In our market, corporates sells different probiotics like soil probiotics, water probiotics and in the name of "PS". These different combination will plays an important role in the shrimp pond. 

Some of the myth also there..... 

If there is a lack of energy sources for any bacteria, then their actions will be very minimal and not effective in the pond environment. 

Be Careful at using of probiotics and probiotics. 

Thank you....

Better clarification about pH and Alkalinity in shrimp pond. Water quality series -3

Image
  Hello everyone:     Most of us confused between pH and alkalinity in the pond ecosystem. If there is low concentration of pH and alkalinity means we can increase but if there is high pH and alkalinity means it is some difficult to reduce .           pH and Alkalinity are related but different. pH and Alkalinity:       If you have shrimp pond then you definitely know the variance of pH in the water. You want to know means , you can check 4 to 5 times in a day. you must saw the pH fluctuations. Yes, pH is very important factor determines the shrimp culture. based on the level of pH you can tell , what happening in your shrimp pond.       Fluctuations of pH is mainly determined by amount of carbon dioxide in your pond water. Other factors like soil pH, soil deposits like calcium carbonate, planktons density also determines the changes of pH in your water.   pH :       I am also tell the same meaning, pH is determined by hydrogen ion concentration.             pH low - high hydrogen

How copepods develops in shrimp pond after applying fermented juice?

Image
Hello everyone:      Are you know which is shrimp favourite food in zooplanktons? Yes, it is copepods. Shrimp eats more copepods which is present in the pond.       In last blog, I told about the reactions and preparation of fermented juice using organic substrates. It is the continuation of that blog. In this I will tell about how zooplanktons(especially copepods) developed after fermented juice application. Main purpose of fermented juice in shrimp pond:      Increase the beneficial microbial colonies by fermentation and produce various substances which is beneficial for beneficial organism growth. After application, it will forms the microbial proteins in the water column. It serve as a natural food for shrimp at stocking time.     Initially, we have to give some natural live feeds because it increases the strength and natural immune system of the Shrimp. So only we prepared for development of zooplanktons in the pond.   What are planktons?         Phytoplankton and Zoo

How temperature plays major role in shrimp farming.(Water quality series - 1)

Image
Hello everyone:      Today we will see the importance of temperature in shrimp culture. What are the problems will come due to the temperature variance in shrimp pond.      Most of the persons who doing shrimp farm must know about the things what happened during temperature Change.       Shrimp grows very fastly, but we can't culture throughout the year. Why?     If you are doing intensive or super intensive system means no problem. But you are doing the culture of shrimp on outside means you have to fix the culture days based on climate change(keep in mind). Ok let's jump into topic. Temperature :       Most of the farmers doing in outer earthern pond. So in these situations, temperature plays important role in growth of our shrimp. We all focus only on ammonia, nitrite, H2S, but indirectly temperature plays very crucial role.         Heat is produced in water due to sunlight. Because sunlight have some energy in the form of photons , when it comes to contact with
