Some of feeding strategies for shrimp growout.


Hello everyone:
         We will see some of important strategies for feeding.

Feeding based on body weight.
       It is better to go for feeding based on the average body weight of your shrimp. If your shrimp have 10 gram weight and you go for 3% of the body weight which means 0.35 gram you have to give to your shrimp. First observe the average daily growth and weight by sampling. By this you fix the day feed by the biomass and go for feeding with the help of check tray. 

My suggestion:
        If you are culturing with high stocking density means, the feed and wastes are always high. So properly use the aerators for sludge accumulation at the centre. Properly use probiotics to your pond. It is better to avoid feeding at centre of the pond.
      If you feed to the centre of the pond means, the animal will disturbs the sludge at the time of taking feed. It leads to release of toxic gas like hydrogen sulfide. 
       It is better to maintain the dissolved oxygen level at more than 3.5 or 4 ppm at the centre of the pond. Try to maintain always high dissolved oxygen to the entire pond.

Different people doing different types of feeding like.
     * Using demand feeder.
     * Bundh feeding.
     * Boat feeding and also boat feeding with line.

For large sized ponds, bundh feeding are not suitable.
      It is better to make the perfect feeding regions for the pond. Always put the feeds on the same places. Don't put the feed in centre of the pond.
      In that feeding zone, we must maintain proper Dept. Depth is very important for high stocking densities.
     Use the same region for feeding.
     Equally distribute the feeds at the feeding region to avoid crowding and feed deficient and cannibalism.
      If you put in same place means, all the shrimps comes to the place and weaker shrimp can't take feed and leads to size variation.
      So fix the feeding zone and equally distribute the feeds to those zones.

Reasons for size variation :
      * Improper seed selection.
      * It may due to the disease like EHP or any other disease.
      * It may due to improper distribution of feed to the pond.
      * It may due to selection of wrong feed. Or the feed have improper nutrition balance.

     So we have to overcome this by proper feeding......  
      Check tray feeding is very important. It is very important for feeding time.
      If the temperature high means then it increases the metabolic rate of the shrimp and that time feed intake will go somewhat high.

You can observe the feed wastage by faster formation of ammonia in your pond. You can observe the feed wastage by water colour in your pond.
        Feed must be stored in proper place . It must be present in optimum room condition. We must prevent the rancidity and oxidation in feed.

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
