What we thought is different in white muscle formation in vannamei.

Hello everyone:
      Today we will see about formation of white muscle in shrimp. 
In general..... 
     If we saw , white muscle in shrimp means, we say it is due to minerals deficiency. But my pond have optimum minerals range, then what is the reason? 
   In around the world, several diseases like IMNV ( Infectious myonecrosis virus) and Penaeid white tail disease ( by noda virus) are identified. 

What I do if I saw white muscle? 
     First you must know about different reasons for white muscle. It may be due to.. 
           - Minerals deficiency. 
           - It may be due to minerals imbalances in your pond. 
           - It may be due to sudden change or increase of temperature and salinity of your pond. 
      When the temperature rise, then you can saw small patches of white muscle in your shrimp. It is due to coagulation. 

Other than this.... If your shrimp gets white muscle in severely , you have to check all parameters. Then clearly observe for presence of any lesions in the body. 
         In case of any pathogenic infections, it creates some cell death and causes haemocytic infiltrations. By this, we can surely tells it may be due to pathogen... 

Regarding infectious myonecrosis virus and Penaeid white tail disease have similarly same signs. But the causative agent is different. These two are noticed in foreign countries. 
    In many local farms, shrimp gets tested for both virus, but results shows negative. But signs are similar. Another advantage is, it doesn't causes mortality. The previously seen virus have some signs of lesions, presence of Cytoplasmic inclusion bodies.. It affect first the sarcomeric structure of the shrimp. It coagulate muscles.... 

Thing to remember.. 
        I have optimum minerals profile, I have maintained optimum DO levels, I maintained optimum minerals ratio, these have no problems. When the temperature get increases, then the sign shows like this. 
   In case of white muscle diseases , it shows less mortality only. Maintaining good water quality leads to good culture... 

What I do if I saw red colour shrimp in pond? 
       Many persons seen this. This red colour is due to Chromatopores in shrimp. If your shrimp gets dissolved oxygen problem , then it goes under stress. It causes red colour in legs. you put your shrimp in normal water and observe the colour. If the colour changes then we can tell it is due to stress. 
      If the colour not changes , then it may be due to any presence of pathogen. Immediately check animal vibrio conditions. 

# Try to maintain your pond dissolved oxygen levels at more than 4 ppm. 
# Try to optimize the feed. 
# Try to control all water quality parameters at optimum levels. 
     Many diseases sign starts with red colouration of shrimp body. For more info.. Contact me..  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
