Increase feed digestibility and absorption in vannamei.....


Hello everyone:
          Today we will see about how to increase feed digestibility and feed intake in vannamei.... 
Vannamei has a good market price in international market... Due to its faster growth and reduced cannibalistic nature, it is mostly cultured species in the world. 

Increase the feed digestibility.... 
          Different problems related to the gut has arises from 30 DOC onwards on vannamei farming... 
    * Presence of harmful pathogens on the stomach. 
    * Imbalance in the gut microbiota.
    * Poor quality feed. 
    * Poor water quality management and treatment. 
    * Irregular feeding. 
    * Absence of primary productivity. 
    * Poor conditions of muddy bottom. 
    * Improper storage of feed will get rancidity, if you gave that feeds to the shrimp, then also affect gut health. 

 These are the some of the reasons which leads to the occurance of gut problems. Lack in the secretion of stomach enzymes also will leads to the improper digestion. 

Energy to the shrimp.... 
1.Digestion of food particles. 
2. Absorption of valuable nutrients from the food. 

These above two are very important. If any lacking in the above two then leads to problems in gut of shrimp. 

Solutions.. 
 * Now many people found white gut and white fecal in the early stages of the culture period. We have to prevent or at least postpone that happenings. 

1. Select the good seed for stocking. Clearly get the details of hatchery, and all must do the stress test before stocking into the pond. 
2. Culture at nursery in farm. My suggestion is try to increase the plankton productivity in the nursery pond. It may helps to ensure the good growth of shrimps at nursery. 
3. Don't allow the growth of harmful pathogens in surrounding water. So, you have properly use the probiotics. 
4. Avoid the seepage ponds. 
5. Boost the primary productivity at regular intervals. 
6. Use gut probiotics at least for one meal in the earlier stages of culture period. 
7. Give feed supplements and use antioxidants like vit C at regulat intervals in the feed. 
8. Try to use some of the chemo attractants in the feed. It will stimulates the shrimp to fastly take the feed. Many chemo attractants like fish solubles, inosine etc... Natural attractants like fish meat or clam meats etc... 
9. Use some of zeolite compounds with less than 1% inclusion in the animal diet.. It will provides some trace minerals to gut and helps in digestion. It also helps to remove the toxic metabolites present on the stomach of the shrimp. 
10. Try to give immunostimulants in the earlier stages of the culture. It will boost the immunity and helps for faster growth of shrimp. 
11. Some of the digestive enzymes like proteolytic and amylolytic enzymes can be added for the better digestion and absorption at the gut. 
12. Maintain balanced gut microbiota by giving gut probiotics, it helps for better digestion and absorption. It also prevents the white gut and white fecal. 

What amount of food we gave to the shrimp is not a matter.. How it creates an impact is the matter. More digestion and absorption also leads to create an impact on gut health. So the feeding and feeding frequency is very important. 

 Except in the earlier stage, other than Don't go for more frequency of feed to the shrimp in the summer times.

           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
