Aquaponics: Fish, Plants, and Bacteria in SEA:
Aquaponics is a sustainable food production system that combines aquaculture (raising fish in water) with hydroponics (growing plants without soil in water). In an aquaponic system, the fish waste provides nutrients for the plants, and the plants help to clean the water for the fish. This creates a closed-loop system that is both efficient and environmentally friendly.
How Aquaponics Works
There are several different types of aquaponic systems, but they all work on the same basic principle. The fish waste is broken down by bacteria into ammonia. The ammonia is then converted into nitrates by other bacteria. The nitrates are essential nutrients for plants, so they are absorbed by the plant roots. The plants filter the water, removing the nitrates and other impurities. The clean water is then returned to the fish tank.
Benefits of Aquaponics
Aquaponics has many benefits over traditional agriculture. It is more water-efficient, as it uses 90% less water than soil-based agriculture. It is also more productive, as it can produce up to 10 times more food per acre than traditional agriculture. Aquaponics is also more sustainable, as it does not require the use of pesticides or herbicides.
Types of Aquaponics Systems
There are three main types of aquaponic systems:
- Deep water culture (DWC): In a DWC system, the plant roots are suspended in a nutrient-rich solution.
- Nutrient film technique (NFT): In an NFT system, the plant roots are grown in a channel that is lined with a thin film of nutrient-rich solution.
- Media culture: In a media culture system, the plant roots are grown in a growing medium, such as gravel or perlite.
What Can You Grow in an Aquaponic System?
You can grow a variety of plants in an aquaponic system, including leafy greens, herbs, tomatoes, peppers, and cucumbers.
Fish for Aquaponics
The most common types of fish used in aquaponics are tilapia, perch, and goldfish.
Market size in SEA:
The aquaponics market in Southeast Asia is expected to grow at a CAGR of 12.60% from 2023 to 2028, reaching a value of USD 1985.3 million by 2028. The market is driven by several factors, including the growing demand for sustainable food production, the increasing popularity of organic and locally grown produce, and the need to find alternative sources of protein.
Southeast Asia is a region with a strong tradition of aquaculture, and this has helped to lay the foundation for the growth of the aquaponics market. The region is also home to a growing population with a rising disposable income, which is expected to further fuel demand for aquaponic products.
The fish segment is expected to be the largest market segment in Southeast Asia, accounting for over 50% of the total market value in 2028. The most common types of fish used in aquaponics in the region are tilapia, perch, and goldfish.
The plants segment is also expected to grow significantly, with a CAGR of 13.20% from 2023 to 2028. The most common types of plants grown in aquaponics in Southeast Asia are leafy greens, herbs, tomatoes, peppers, and cucumbers.
The bacteria segment is expected to grow at a CAGR of 11.80% from 2023 to 2028. Bacteria are essential for the proper functioning of aquaponic systems, as they break down fish waste into nutrients for plants.
The key countries in the Southeast Asia aquaponics market are Thailand, Indonesia, Vietnam, Malaysia, and Singapore. Thailand is the largest market in the region, accounting for over 40% of the total market value in 2023. Indonesia is the second largest market, followed by Vietnam, Malaysia, and Singapore.
The aquaponics market in Southeast Asia is fragmented, with a large number of small and medium-sized enterprises operating in the market. However, there are a few large players in the market, such as Nelson and Pade, Aquaponic Source, and Backyard Aquaponics.
The future of the aquaponics market in Southeast Asia is bright. The market is expected to continue to grow at a strong pace, driven by the factors mentioned above. Aquaponics has the potential to play a significant role in addressing the food security challenges in Southeast Asia.
Here are some additional insights into the Southeast Asia aquaponics market:
