Alkalinity plays major role in nitrification process.

Hello everyone:
        Today we will see about importance of alkalinity for nitrification process in shrimp pond. 

Did you know? 
       pH and alkalinity plays major role in nitrification process. 

How did the wastes are converted in shrimp pond? 
       All are know that we are using high protein feed in pond with high stocking density. If you feed 50 kgs per day means then you can imagine how much nitrogenous wastes accumulate in your pond. 

      They are mainly converted by nitrification process. 

Heterotrophic or autotrophic:
      In our culture system, we have to maintain stabilized heterotrophic colonies for better pond bottom management. 
      We are using heterotrophic and autotrophic bacteria for pond management. 

What they are doing? 
        They are mainly involved in nitrification process. They are converting the huge organic wastes into energy. 

What they need for that process? 
       The pH and alkalinity plays a major role in the nitrification process. In general pH and alkalinity will drop in nitrification process. 
        Most of us facing the common alkalinity problem in our pond. 
        Alkalinity must need for the  nitrification process. If alkalinity not sufficient, then the nitrification process will stop. 

It leads to..... Poor water quality and toxic gas formations. 

When the pH drops below 7.2 and goes above 8.5 those problems will occurs. The optimum pH range must be 7.2-8.5 for better nitrification process. The alkalinity must be above 120 mg/l.

When the intracellular pH of the bacteria lower than the extracellular environment then the ammonia will penetrate into the bacteria and inhibit the process. 

When the intracellular pH of the bacteria is higher than extracellular environment then the acid will inhibit the bacterial growth. 

Maintanence of pH and alkalinity is important factor in shrimp farming. 

Kindly refer my previous blogs to know info about nitrification and beneficial bacteria.

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

  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)

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
