Fish-Seaweed Co-Culture Calculator
* Based on peer-reviewed IMTA models (Chopin et al., 2012; Kim et al., 2015).
About the Fish-Seaweed Co-Culture Calculator
The Fish-Seaweed Co-Culture Calculator is a scientifically validated tool designed to optimize integrated multi-trophic aquaculture (IMTA) systems combining finfish and macroalgae. Using peer-reviewed nutrient mass balance, growth kinetics, and bioeconomic models, it predicts fish biomass gain, seaweed yield, and nutrient recycling efficiency. This calculator supports sustainable Fish-Seaweed Co-Culture and carbon sequestration. For expert guidance, visit Agri Care Hub.
Importance of the Fish-Seaweed Co-Culture Calculator
The Fish-Seaweed Co-Culture Calculator is essential for regenerative ocean farming. Fish-seaweed IMTA can reduce nutrient discharge by 60–90%, increase total yield by 30–50%, and generate additional revenue from seaweed products. This tool helps farmers design balanced systems, quantify environmental benefits, and access sustainability certifications. By integrating fish waste streams with seaweed nutrient uptake, it enables precision aquaculture aligned with UN SDG 14 and blue economy goals.

Purpose of the Fish-Seaweed Co-Culture Calculator
The primary purpose of the Fish-Seaweed Co-Culture Calculator is to transform complex IMTA dynamics into actionable insights. By modeling nutrient flows and trophic interactions, it empowers farmers to create balanced, profitable, and regenerative systems. This tool supports the global shift toward circular aquaculture and ocean health restoration.
Scientific Foundation of the Calculator
All calculations follow peer-reviewed methodologies:
- Fish Waste: N_out = Feed_N × (1 - Retention) (Chopin et al., 2012).
- Seaweed Growth: SGR = f(T, Light, DIN) with Michaelis-Menten uptake.
- Nutrient Recycling: 60–90% N and P removal by seaweed.
- Carbon Sequestration: 1.5–2.0 tons CO₂ per ton dry seaweed.
Models are validated in Aquaculture, Algal Research, and Marine Policy.
Applications in Fish-Seaweed Systems
The Fish-Seaweed Co-Culture Calculator supports diverse configurations:
- Offshore salmon + sugar kelp in Norway and Canada
- RAS tilapia + Ulva in recirculating systems
- Seabass + Gracilaria in coastal ponds
- Milkfish + Kappaphycus in tropical waters
It is used by governments, NGOs, and industry to scale sustainable Fish-Seaweed Co-Culture.
Benefits of Using the Calculator
The Fish-Seaweed Co-Culture Calculator delivers proven benefits:
- Nutrient Recycling: 60–90% reduction in waste discharge.
