Copper and shrimp - Facts.

Hello everyone:
      Today we will see about some of the interesting things about the relationship between copper and vannamei. 

Is copper good or bad? 
      Copper is a important trace mineral which is required by crustaceans for their function especially in hormone and enzymes synthesis. When the copper is exposed to excess level then it cause severe problem to shrimp then leads to death. 

Respiration:
      Copper is a important carrier in oxygen transport in crustaceans because haemocyanin contain copper as a transport medium. 

Enzymes:
      Some of the copper dependent enzymes are found in the body of crustaceans. But how to predict the required level of copper? Yes, it is depends on various intrinsic and extrinsic factors. 

Molting and reproduction:
      It is proven that certain amount of copper supplements induces molting in  shrimp. It also induces gonadal development and maturation. 

      Several hemolymph proteins also contributes to the new shell formation during molting time. At that time copper also plays important role in shell hardening. 
      The amount of minerals in shrimp body will varies from different molting stages. Some of prophenoloxidase in shrimp also depends on the copper and plays important role in shell hardening and repair. 
Hepatopancreas in shrimp stores and releases copper during molting times. 
Hemolymph activity shows increasing during Ecdysis. At that time these trace minerals also plays role in shell hardening. 

When the dose exceeds the limit then it cause respiratory stress and mortality in shrimp. 

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
