Importance of biofilm formation in shrimp culture... Part 1

Hello everyone:
         Today we will see some interesting topic about biofilm formation and uses in shrimp culture...
         In Aquaculture, we using different artificial pellet feeds.. only very few of people are culturing with natural productivity.. we always stock in high stocking density. Minimum duration of time, we have to harvest. So we give more feeds and leads to change in water quality.

Biofilm function in shrimp pond..
        Before stocking, all are applying fermented juice. I already clearly posted about this. At that time we continually runs the aerator.. we do chain dragging for proper mixing of nutrients and also make the soil strengthen. 
        Biofilm consists of different organism like microalgae, different beneficial bacterial colonies, protozoans... These all are very rich in nutrients. They have growth promoting substances, many bioactive compounds, antibiotics compounds... These all are present in the biofilm.
          Many researches told, there is an increased growth and survival of species which is cultured with substratum of biofilm in pond.

How biofilm formed in water...
         Generally it is formed on any living or non living substrates. Keep in mind, biofilm is a group of several organisms. Mostly microbial colonies.
       Example : In our body also biofilm present. Under the armpit. The smell also caused by bacteria. They formed in a group called biofilm.
        In aquatic environment, the organic substances present. If organic matter present means then small microbial colonies formed on the surface.. then they reproduce and produces extracellular polymeric substances into their environment.They forms one matrix , within the matrix all other organism like microalgae, protozoa are present..
         Biofilm can formed on the submerged soil, or any other artificial substrates which is present in the pond.
          The matrix present in the biofilm also serve as a shelter for them.. they need nutrients for the growth..Many researches told, they play very important role in the maintaining water quality in shrimp pond. Under High stocking densities, so much of ammonia is produced, at that time biofilm plays very important role in converting these toxic nitrogenous wastes...
         The structure and size of biofilm is fully depends on nutrients availability in pond.

Many other interesting facts about biofilm in shrimp pond will be posted tomorrow....
The key role in ammonia control, how inhibits harmful pathogens I'm aquatic ecosystem, presence of substrates in water...

All topics will be posted tomorrow.

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)

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
