Types of Vaname Shrimp Feed

1. Natural Feed

Vannamei shrimp natural feed is a type of feed that comes from nature without being processed first. This natural food can be phytoplankton and zooplankton which were previously prepared during farm preparation, as well as other animals and plants.

Traditional types of shrimp farms usually rely on this type of natural feed. Meanwhile, in semi-intensive, intensive, and super-intensive farms, natural feed is usually used as a companion to the artificial feed that has been given.

2. Artificial Feed

In contrast to natural feed, artificial feed is a type of feed that undergoes a processing process first to form pellets, crumble, or powder. Usually, a good artificial vannamei shrimp feed has additional nutrients to accelerate the growth of shrimp during cultivation.

Based on the shape, artificial feed is divided into three types, namely pellets, granules (crumbles), and powders.

– Pellet

Pellets are artificial feed for vaname shrimp in the form of tubes with different levels of hardness. In the pellets, there are usually special nutrients to accelerate the growth of shrimp. Starting from protein, carbohydrates, fat, fiber, and other important nutrients.

Vannamei shrimp feed in the form of pellets is generally used to feed shrimp that have entered the juvenile stage (juvenile) until ready to harvest.

– Granules (Crumble)

Granules or crumble are vannamei shrimp feed in the form of coarse granules. Usually, this type of shrimp feed is given to shrimp aged 16-45 days.

Granules can be made from crushed pellets or agglomerated powder feed types. Meanwhile, in terms of nutritional content, the type of vaname granule shrimp feed has nutrients that have been adjusted to the age of the shrimp.

– Powder

5 Tips to Achieve Profitable Biofloc Vannamei Shrimp Farming

Biofloc technology in vannamei shrimp farming is an innovative approach that has gained popularity recently. This technology involves using microorganisms in the cultivation system, which can help maintain water quality and enhance shrimp health.

In vannamei shrimp farming, biofloc technology has proven effective in reducing feed costs, increasing shrimp’s growth rate and survival, improving the immune system, and minimizing the risk of diseases.

However, before implementing bio floc vannamei shrimp farming, it is essential to understand how this innovative technology works. Read on to learn more in the following article.

How to Use Biofloc in Vannamei Shrimp Farming?

The initial step in implementing bio floc technology for vannamei shrimp is creating a system. This system involves creating a cultivation environment that promotes the growth of beneficial microorganisms such as bacteria and algae.

Creating a biofloc cultivation environment can be done by maintaining a high content of organic matter in the water, which serves as a food source for microorganisms.

To manage the biofloc system, there are several factors to consider, including pond size, the stocking density of vannamei shrimp, and the type of shrimp feed used.

The ideal pond size for implementing biofloc technology is between 500 and 1000 square meters. The stocking density should be manageable, as it can lead to the accumulation of organic matter that reduces oxygen levels in the water. Additionally, the feed should have a high protein content and be easily digestible by shrimp.

Benefits of Using Biofloc in Vannamei Shrimp Farming

1. Improved Water Quality

One of the main benefits of implementing bio floc technology in vannamei shrimp farming is its ability to help maintain optimal water quality. The microorganisms in this system can break down organic matter, reducing ammonia, nitrite, and nitrate levels in the water.

2. Cost Savings

Biofloc technology can also help you save costs compared to traditional shrimp farming methods. The microorganisms in the biofloc system can serve as a natural source of nutrients, reducing expenses on feed. Furthermore, bio floc vannamei shrimp farming can maintain water quality in good condition for longer, reducing the need for frequent water replacement.

3. High Survival and Growth Rates

Biofloc technology has been proven to enhance the survival and growth rates of vannamei shrimp. This is because the microorganisms in the system provide additional nutrition that promotes shrimp growth and development.

Cultivating Vannamei Shrimp with Biofloc System

Vannamei shrimp biofloc has become a popular cultivation system lately. Biofloc technology was first applied by Dr. Yoram Avnimelech in Israel and experienced immediate success. Finally, the biofloc system was also implemented in shrimp ponds in Indonesia.

In a way, the vannamei shrimp aquaculture biofloc system is a form of innovation to address feed problems experienced by farmers. The reason is by implementing the biofloc system, the shrimp’s natural feed supply becomes more abundant.

Farmers who want to apply the biofloc system to vannamei shrimp cultivation must practice it correctly because a bit of wrong in practice can be fatal.

Therefore, here we have summarized the method of cultivating vannamei shrimp using the biofloc system, which you can use as a reference.

What is the Biofloc System?

Biofloc is a bunch of microorganisms such as bacteria, protozoa, fungi, plankton, and organic matter from undecomposed waste.

While the biofloc system attempts to utilize leftover shrimp feed waste to become microbial feed, the rest of the feed waste will be degraded, and the microbes in it will develop and multiply until, finally, the floc is produced.

Floc can be a good source of protein for shrimp. This is because decomposed organic compounds contain carbon (C), hydrogen (H), oxygen (O2), nitrogen (N), and phosphorus (P) compounds.

With the vannamei shrimp biofloc, the farmers can reduce operational costs, which are usually used to purchase feed. This is because the biofloc system can lessen the Feed Conversion Ratio (FCR) while minimizing disease outbreaks.

However, keep in mind that the biofloc system does not affect overall farm productivity because the microorganisms formed only serve as additional feed.

Vannamei shrimp cultivation using the biofloc system can be applied to start from intensive to super-intensive system ponds that have high stocking densities. However, firstly the pond must have a high level of aeration with the appropriate wheel position. The pond must be covered with concrete or high-density polyethylene (HDPE), as well as additional pellets and molasses.

In addition, farmers must always carry out biofloc control during vannamei shrimp cultivation.

How to Cultivate Vannamei Shrimp with the Biofloc System

Until now, many Indonesian shrimp farmers are interested and have applied the biofloc system. However, few also experience failure due to a lack of understanding of this technology.

Therefore, here is a method of cultivating vannamei shrimp with the biofloc system that you can practice.

1. Prepare the Pond very Well

The vannamei shrimp biofloc system can only be applied in some ponds. Particular standards must be met so that the cultivation of vannamei shrimp goes well and does not suffer losses.

The standards for pond ponds that must be met include pond sizes adapted to the cultivation system, ponds that do not leak and have been coated with thick HDPE concrete or plastic, sound aeration systems, and pond heights ranging from 0.8-3 meters.

2. Choose the Right Probiotic Bacteria

The vannamei shrimp biofloc system relies on probiotic bacteria for each pond. Bacillus subtilis is a type of probiotic bacteria that can be selected because this bacteria can decompose nitrogen elements properly and can maintain water quality.

Another type of bacteria that can be used is Bacillus cereus which can form bacterial flocs while controlling the growth of green algae.

3. Make Biofloc Starter

After selecting probiotic bacteria, the next step is to make a biofloc starter. This stage is the same as fermentation to increase the number of bacteria in the pond, which functions as a quality guard for Biopolymer (PHA), which helps the process to suppress harmful pathogens.

4. Spread High-Quality Shrimp Fry

When the ponds with biofloc technology are ready, farmers can start spreading the shrimp fry into the pond. However, to get the best quality cultivation results, choose high-quality and certified fry.

5. Perform Proper Feed Management

When the flock has not been formed, farmers can provide feed like ordinary vannamei shrimp cultivation. For example, feeding in pellets twice a day according to needs.

Then when the flock has begun to form, you can start reducing feeding because this is where the role of floc is as a natural food source for shrimp. With this flock, farmers can reduce FCR and save farm operational costs.

6. Ensure Dissolved Oxygen Supply (DO) is fulfilled

When choosing to use biofloc technology, farmers must ensure a continuous supply of dissolved oxygen (DO). This is because ponds that lack an oxygen supply can cause the shrimp in them to die.

To ensure that the supply of dissolved oxygen (DO) is met, farmers can use aerators or waterwheels as additional tools to supply extra oxygen. In addition, make sure the number of aerators or water wheels per the pond’s area.

In biofloc vannamei shrimp farming, the aerator or waterwheel not only acts as an oxygen supply but also keeps the biofloc suspended. However, it should be noted that high levels of suspended biofloc biomass can cause a decrease in pond water quality and ultimately result in crop failure.

Advantages and Disadvantages of the Biofloc System

The biofloc system is only sometimes superior to the vannamei shrimp farming system. There are positive and negative sides to this cultivation system. Following are the advantages of biofloc technology:

Very high biosecurity
Production capacity and carrying capacity are usually 5-10% higher
Shrimp grow bigger with lower FCR
15-20% lower production costs

Meanwhile, the shortcomings of the biofloc system include the following:

Requires a high energy supply for the aerator
Failure of energy supply for more than 1 hour can be fatal and critical
The biofloc pond must be lined
Technicians must receive specific knowledge and training to understand this technology fully.
