Seepage issues in aquaculture ponds...

Hello everyone:
Today we will see about seepage issues in aquaculture. 

First I want to tell one example - Life is not same for all people, it varies depends on individual person situation, if any good thing is happened to one person, the same thing won't work for another person.. 

Wait... Why are you telling this... 

Most farmers thought seepage is very good... 😳 because if any succeed people have seepage pond then they thought seepage pond is good. But it is not worked for all ponds. 

Now you compare my example! 

Seepage:
      Site selection and pond construction is very important. Perfect soil with good water holding capacity is important for pond construction. 

* The adjacent site must not be taller than your pond. 
* Your dike must be perfect height enough to prevent entry of outside water. 
       When the pond is aged or the soil is loosed or your site is shallow or higher from the near water sources are the important factors leads to seepage. 

It is like diffusion process.. Movement of water from high concentration to low concentration. 
        The pond embankment must be properly compacted at regular interval of time. The soil selected for dike construction must have plasticity. It means clayey soils not preferred dor dike construction. Because when it becomes dry then it breaks and leads to seepage. 

      Seepage water carries water borne pathogens into pond. It causes various difficulties on culture. It reduces the water level in pond. The soil can't able to hold more nutrients. 

Treatment:
        Most of the treatments are cost effective. Pond liners requires more cost. Most of the farmers in India follow culture in earthern system only. 
       Sodium bentomite - it is effective coagulant and absorbs more water and widely it is used as pond sealer. But excess amount reduces pH ( due to presence of aluminium and iron) in pond and absorbs more nutrients. 
        Some farmers strongly compact the bottom layer with bentomite. 
        Some farmers uses clayey soil over the top of the bottom and make it more compact. 
         Other pond materials must be properly sealed like pipes, sluice edges and others.. 

Proper selection and proper renovation at particular interval make the pond more productive... 
                        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
