Different roles of microorganisms in shrimp pond ecosystem - part 2

Hello everyone:
    Last blog, we saw about the importance of photoautotrophs in shrimp pond.
   In this blog, we will see about chemoautotrophic bacteria. 

Chemosynthesis is a process in which microorganisms actively utilize inorganic chemicals such as H2s, Hydrogen, carbon monoxide, ammonia, methane, iron, Nitrite, nitrate to produce their food. 

These type of bacteria didn't utilize carbon as a major energy source. 

Important : Farmers pls be aware of using carbon source for every probiotics application. 

They actively works in both aerobic and anaerobic conditions. 

Sulfur bacteria which oxidize H2S to sulphur and sulphates. Most commonly involved species are Thiobacillus. 

Nitrogenous bacteria which are mainly involved in nitrification process. We all are knew about that. 

Ammonia - nitrite - nitrate
Species involved in this process are Nitrosomonas and nitrobacter. 

Hydrogen bacteria which are uses oxygen in the aerobic condition and uses hydrogen in anaerobic conditions. 

Methanotrophs oxidize methane which present in the pond. They works both in aerobic and anaerobic conditions. 
Species are Methylococcus capsulates. 

Iron bacteria which oxidize ferrous iron to ferric iron. 

These are the important chemoautotrophic bacteria. 

Most of us are confused to clarify the definition for organic matter. Let see the proper definition... This term is used oftenly in pond system. 

Organic matters : These are mostly derived from living organisms , it is capable of decay, basic structures in organic matters are cellulose, tannin, lipids, lignin, proteins, sugars. 

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
