Raceway series; Introduction and overview of Raceway aquaculture -1

Hello everyone, 
   Today, we see the importance of Raceway aquaculture system. A successful system for fish (specific to certain species). It is an underrated system and need more research and demonstration for warm water species too. 

'Intensification' is the key criteria need to increase production per unit area in aquaculture. To achieve higher production, the system must be improved in terms of efficiency. 

Top factors need to be considered for designing system, 
1. Carrying capacity
2. Water quality and water availability
3. Species
4. Feed
5. Market availability

In general, Raceway aquaculture system works based on the input of water flow. It is clear that, production is highly depend on the water input and flow. The flowing water effectively removes all the metabolic wastes from the tank and discharge on the other end. 

These systems built by different sizes and dimesions. The most common design is rectangle. The length of the system must not be more than 100 ft. 

Working of the system:
Tanks mostly constructed with cement. It is built on the lower elevation from the ground to get easy access of water. By using gravity, the water is collected and flowed through the tanks. The inlet pipe must be built higher from the tank for better aeration. The water passed into the tanks with high force and collects all the metabolic and feed wastes in the end. At the end, the outlet is constructed to remove this waste and effluents. 

By this, the water quality will be stable and less chance for ammonia. Some cases, supplemental aeration also provided. Though the system is intensified, the feed quality must be good to improve the overall fish health. Because species cultured in the system is highly depends on formulated feed. 

In some cases, people tried to use water by recirculation. In the end of the tank, waste water is collected and used again to the tanks. The success is highly depends on the working and efficiency of the filtration system. 

Fact : Cold water hold more oxygen than warm water.

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 me...

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 pon...

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 ...
