6. Murray Cod: A Unique and Flavorful Addition

  • Culinary Flexibility: With pearly white flesh, Murray cod is versatile in cooking methods and rich in omega-3 fatty acids;
  • Size in Aquaponics: Although naturally large, in aquaponics systems, they grow to a more manageable size of 25.5 inches and 11 pounds;
  • Behavior: Being carnivorous and territorial, larger cod should be segregated to prevent cannibalism.

7. Trout: Nutrient-Rich and Tasty

  • Diet Influence: Their carnivorous diet contributes to their meaty, protein-rich flesh;
  • Optimal Conditions: Thrive in cooler water temperatures (56°-62°F) and pH levels of 6.5–8;
  • Growth Cycle: They mature in 12–18 months, offering bountiful harvests under ideal conditions.

8. Salmon: A Premium Selection for Controlled Water Environments

  • Nutritional Value: Salmon, a top choice for health-conscious consumers, is ideal for cultivation in controlled water systems;
  • Feeding Habits: They are typically nourished with pellets composed of 70% plant-based ingredients and 30% fish oil and meal, contributing to their rich taste and high omega-3 content;
  • Market Demand: Salmon’s popularity ensures a consistently high market value, making them an excellent option for larger-scale ventures;
  • Social Behavior: These sociable creatures can coexist harmoniously with other aquatic breeds;
  • Environmental Needs: They prefer cooler water temperatures but necessitate spacious tanks due to their size;
  • Growth Timeline: Salmon require approximately two years to reach maturity, demanding patience and long-term planning.

9. Carp: Underestimated Yet Rewarding in Clean Environments

  • Taste Improvement: In the pristine conditions of a controlled water system, carp can develop a more refined taste, shedding their usual muddy flavor;
  • Resilience: These breeds surpass tilapia in hardiness, thriving in diverse water qualities and temperature ranges;
