Shrimp- aquatic animals polyculture

Table of Contents

Professionals in all industries are always looking for solutions to overcome obstacles, problems, and limitations to achieve more profit. The shrimp farming industry, as a powerful industry in the food industry, always faces problems such as diseases, pond pollution, and high production costs. Various solutions have been studied and tested by researchers to overcome and alleviate these obstacles and problems. In recent years, polyculture of shrimp and other aquatic animals has been one of the solutions used in the shrimp farming industry. The use of this method has been studied in different parts of the world and its effectiveness has been proven.

What is polyculture?

In aquaculture, polyculture is the simultaneous cultivation of more than one aquatic species in the same place at the same time. This technique attempts to mimic the diversity of the natural ecosystem.

According to the evidence, the origin of the polyculture goes back to China, when the Chinese tried to utilize the available seafood by farming several species of aquatic animals together many years ago.

The polyculture of shrimp and other aquatic animals has not yet become a common practice among farmers. However, several studies have proved its efficiency and effectiveness.

This method has many advantages, including

1. Improving the farm environment and preventing disease

2. Water pollution control

3. High productivity

4. Cost reduction

5. Preservation of biodiversity

6. Optimal management of water resources

7. Increasing production efficiency in the environment

8. Achieve more profit

9. Sustainability of the shrimp farming industry

These advantages are enough to consider this method efficient and profitable in the shrimp farming industry.

Now that you are familiar with the benefits, let’s look at some examples of how shrimp and other aquatic animals are polycultured.

In the polyculture of shrimp and other aquatic animals, it should be considered that the secondary species should be nutritionally and behaviorally distinct from the shrimp and should not be considered as food competitors to the shrimp.

Shrimp-tilapia fish polyculture

Tilapia fish is the second most produced fish in the world. Its habitat is Africa, but nowadays it is farmed in most countries of the world. China produces the most tilapia fish in the world. This fish has different species, the most famous is the Nile tilapia.

Tilapia fish is one of the animals that has shown good and effective results when farmed simultaneously with shrimp.

One of the main advantages of this fish is its high salinity tolerance and good resistance to cold weather. Tilapia fish is omnivorous and feeds on aquatic plants, small crustaceans, phytoplankton, etc.

The results have shown that the polyculture of shrimp and tilapia fish significantly reduces the bacteria in the pool.

Tilapia fish prevent disease transmission by feeding on lethargic shrimp. Also, by stirring up the sediments of the bed, this fish increases the oxidation of the bed.

Thailand is one of the largest shrimp and tilapia polyculture producers.

shrimp-mullet fish polyculture

Another aquatic species that can be farmed simultaneously with shrimp is mullet fish.

This fish has about a hundred different species and lives in most waters of the world. One of the important advantages of this fish is its good nutritional value, high salinity tolerance, easy breeding, and high survival rate.

The mullet fish feed on worms, algae, plants on the bed, etc., and has a good feeding behavior towards the shrimps.

Shrimp-mullet fish polyculturecleans the pool bed and limits the environmental diseases of the shrimp. Also, the mullet fish feed on the shrimp food left on the bottom of the pool, reducing costs.

This method is used in many farms to control water pollution and its effectiveness has been proven.

Shrimp-milkfish polyculture

Milkfish is one of the other aquatic species that are farmed along with shrimp.

Its main habitat is the Red Sea and it is widely cultivated in East Asian countries. Milkfish can live in fresh water and very salty water. These fish feed on planktonic animals, aquatic plants, and other organisms.

One of the most important reasons for shrimp-milkfish polyculture is to prove its effectiveness in reducing shrimp losses due to white spot disease.

In addition to increasing shrimp survival, this method improves shrimp growth, reduces pond erosion, maintains pond water quality, and reduces costs.

These mentioned items increase farm productivity and contribute to the sustainability of shrimp farming.

Shrimp-sea cucumber polyculture

In addition to fish, other aquatic animals such as sea cucumbers can be raised simultaneously with shrimp.

Sea cucumber has a high ability to reduce pollution in shrimp ponds. This aquatic animal lives at the bottom of the pond. It swallows the sediments at the bottom of the pond, which results in the disappearance of pollution and the improvement of the health of the environment. In addition, the length and weight of shrimp will increase as a result of shrimp-sea cucumber polyculture.

Sea cucumber is used as a valuable aquatic resource in the pharmaceutical, medical, and food industries. For the farmer, the income from polyculture is more profitable than growing a single crop.

As it is explained, the polyculture of shrimp and other aquatic animals has several advantages. The most important of these benefits are disease and pollution control, cost reduction, and better productivity and profit.

Of course, polyculture is not limited to the farming of two aquatic animals. Today, other farming methods are used around the world.

Aquaponics

One of the farming methods is based on polyculture. In this technique, aquatic animals and plants are grown in water at the same time. In aquaponic farming, the waste of aquatic animals is used as fertilizer for plants.

One of the most obvious examples of this technique is rice-fish polyculture.

The use of aquaponics has shown positive results. It is spreading rapidly in developed countries.

Who can predict the next innovation in the aquaculture industry?
