The Ultimate Guide to Using Prawns in Aquaponics: A Top Choice Among the Best 25 Aquaponics Species

Aquaponics is a revolutionary method of sustainable farming that combines aquaculture and hydroponics. Among the top 25 fish species used in aquaponics, prawns hold a special place due to their versatility, market value, and high nutrient output. In this guide, we delve into why prawns are an excellent choice for aquaponic systems, exploring their unique traits, care requirements, and the benefits they bring to your aquaponics setup.

Main Points:

1. Growth Rate

Prawns are known for their steady growth, reaching market size in approximately 6-8 months. This makes them a viable option for aquaponics enthusiasts looking for a quick turnaround.

2. Temperature Tolerance

Prawns thrive in temperatures ranging from 77°F to 86°F. Maintaining a stable temperature within this range ensures their optimal growth and health.

3. pH Tolerance

With a pH tolerance of 7.0 to 8.5, prawns are well-suited to aquaponics systems, which typically maintain neutral to slightly alkaline water conditions.

4. Disease Resistance

Prawns have moderate disease resistance. Proper water quality management and regular monitoring can significantly reduce the risk of infections.

5. Oxygen Requirements

Adequate aeration is essential for prawns, as they require moderate to high oxygen levels. Including air pumps or aeration devices ensures their well-being.

6. Stocking Density

Prawns can be stocked at a density of 10-15 individuals per square meter, depending on the size of the tank and the filtration capacity.

7. Feed Conversion Ratio

With an feed conversion ratio (FCR) of 1.5 to 2.0, prawns efficiently convert feed into biomass, making them cost-effective for aquaponics systems.

8. Market Value

Prawns are highly prized in the culinary world, offering a lucrative market value for those seeking to sell their produce.

9. Ease of Breeding

Breeding prawns can be challenging, as it requires controlled conditions and specific water parameters. Many aquaponic practitioners source juvenile prawns from hatcheries.

10. Compatibility with Other Species

Prawns can cohabit with non-predatory fish like tilapia or carp, maximizing the productivity of your aquaponics system.

11. Nutrient Output for Plants

Prawns contribute significantly to nutrient cycling, releasing nitrogen and phosphorus that promote robust plant growth.

12. Hardiness

While prawns are hardy, maintaining consistent water parameters is crucial to prevent stress and ensure their longevity.

13. Water Quality Tolerance

Prawns require clean, filtered water with low ammonia and nitrite levels, which aligns with the best practices for aquaponics systems.

14. Size at Harvest

On average, prawns reach a harvestable size of 30-50 grams, depending on the species and growing conditions.

15. Time to Harvest

They typically reach harvestable size within 6-8 months, making them a medium-term aquaponics investment.

Stocking Density 4 Can be stocked at high densities if water quality is maintained.
Feed Conversion Ratio 4 Efficient converters of feed, especially with high-protein diets.
Market Value 5 High market demand and value in culinary markets.
Ease of Breeding 2 Breeding can be complex, often requires controlled hatchery conditions.
Compatibility with Other Species 3 Compatible with some species but can be predatory towards smaller animals.
Nutrient Output for Plants 4 Produce moderate nutrient levels beneficial for aquaponics.
Hardiness 3 Resilient under stable conditions but sensitive to sudden changes.
Water Quality Tolerance 3 Require good water quality, sensitive to ammonia and nitrite levels.
Size at Harvest 5 Harvest size is marketable and highly desirable.
Time to Harvest 4 Reaches harvest size in approximately 4-6 months.

Overall Score: 56

Pros:

  • High market value and demand.
  • Good growth rate and nutrient output for aquaponics.
  • Adaptable to high stocking densities.

Cons:

  • Requires stable water quality and temperature.
