Top 25 Fish for Use in Aquaponics: Spotlight on Eels

Eel Aquaponics combines aquaculture and hydroponics into a sustainable ecosystem where fish and plants thrive together. Among the top 25 fish species used in aquaponics, eels stand out for their unique adaptability, high market value, and impressive nutrient output for plants. This post explores why eels deserve a place in your aquaponics system and how to optimize their care.

Why Eels are Perfect for Aquaponics

Eels are an underrated choice for aquaponic systems, offering a range of benefits that make them ideal for both beginner and advanced aquaponic enthusiasts. Let’s break down their advantages:

1. High Growth Rate

Eels grow rapidly, often reaching market size within 12-18 months. Their fast growth ensures a quick turnaround for commercial aquaponics systems, increasing profitability.

2. Wide Temperature Tolerance

Eels thrive in temperatures between 15°C and 30°C, making them suitable for a variety of climates. This broad temperature tolerance reduces the need for precise environmental controls.

3. pH Tolerance

Eels are comfortable in pH levels ranging from 6.5 to 8.0, aligning perfectly with the ideal pH for aquaponic plant growth. This compatibility simplifies water quality management.

4. Disease Resistance

With strong resistance to common aquaculture diseases, eels are a hardy choice. Their resilience reduces the need for chemical treatments, keeping your aquaponics system organic and sustainable.

5. Low Oxygen Requirements

Eels can tolerate low dissolved oxygen levels, making them suitable for systems with occasional aeration challenges.

6. Stocking Density

Eels can be stocked densely, with up to 30 kg per cubic meter, depending on the system’s capacity. Their ability to thrive in high densities optimizes space and productivity.

7. Feed Conversion Efficiency

Eels have an excellent feed conversion ratio (FCR), often around 1.2:1. This efficiency ensures they convert feed into biomass effectively, reducing costs.

8. Market Value

Eels are a high-demand commodity in many global markets, particularly in Asia. Their premium price makes them a lucrative choice for commercial growers.

9. Ease of Breeding

Breeding eels in captivity is complex but manageable with the right expertise. If successful, it provides a sustainable stock source for your system.

10. Compatibility with Other Species

While eels prefer a solitary environment, they can coexist with bottom-dwelling species if space and resources are managed effectively.

Nutrient Contributions of Eels in Aquaponics

Eels produce nutrient-rich waste that plants utilize for optimal growth. Here’s how they contribute:

  • Nutrient Output for Plants: Eel waste is high in nitrogen, a critical nutrient for leafy greens and herbs.
  • Water Quality Tolerance: Eels thrive in water conditions that also support plant health, ensuring a balanced system.

Key Considerations When Raising Eels

Water Quality

Maintain clean water by using biofilters and regular water testing. While eels are hardy, consistent quality ensures their health and optimal plant growth.

Feeding Requirements

Eels are carnivorous and prefer protein-rich diets. Commercial eel pellets or live feed can be used for nutrition.

System Design

Design a system with hiding spaces for eels, as they are nocturnal and prefer low-light environments.

Harvesting Size and Time

Eels are ready for harvest when they reach 500-1000 grams, typically within 12-18 months. Their size and timeline make them a versatile choice for both small-scale and commercial setups.

How to Start Raising Eels in Your Aquaponics System

  1. Choose the Right Species: Select species like European eels or Japanese eels for their adaptability and high market demand.
  2. Set Up Your System: Include proper aeration, biofiltration, and water heating systems for optimal eel health.
  3. Monitor Regularly: Check pH, temperature, and ammonia levels frequently to maintain balance.
  4. Source Quality Feed: Invest in high-protein feed for rapid growth and health.
  5. Plan for Harvest: Develop a strategy to harvest eels at their peak size for market.

Eels Scorecard

Fish Name: Eels

Criteria Score (1-5) Notes
Growth Rate 4 Eels grow relatively quickly in aquaculture settings.
Temperature Tolerance 4 They adapt well to moderate temperature ranges (22–28°C).
pH Tolerance 4 Eels can tolerate a pH range of 6.5–8.0.
Disease Resistance 3 Susceptible to some diseases, especially in poor water conditions.
Oxygen Requirements 3 Moderate; they are resilient to lower oxygen levels but still require good aeration.
Stocking Density 5 High stocking densities are possible due to their elongated bodies.
Feed Conversion Ratio 4 Good feed efficiency, especially with specialized feeds.
Market Value 5 High demand in many markets, particularly in Asia.
Ease of Breeding 2 Difficult to breed in captivity; often requires wild-caught juveniles.
Compatibility with Other Species 3 Can coexist with some species but may become territorial or predatory.
Nutrient Output for Plants 4 Produces ample nutrients for aquaponic systems.
Hardiness 4 Resilient to environmental fluctuations, within limits.
Water Quality Tolerance 3 Tolerates some variation but requires clean, well-managed systems.
Size at Harvest 4 Reaches a desirable size for harvest, typically 300–500g.
Time to Harvest 4 Typically 6–12 months, depending on conditions and species.

Overall Score: 60

Pros:

  • High market value and demand, particularly in niche markets.
  • Thrives in high-density systems, maximizing space efficiency.
