Integrated Multi-Trophic Calculator
* Based on peer-reviewed IMTA models (Chopin et al., 2012; Reid et al., 2013).
About the Integrated Multi-Trophic Calculator
The Integrated Multi-Trophic Calculator is a scientifically validated tool designed to optimize species combinations, nutrient recycling, and economic returns in IMTA systems. Using peer-reviewed mass balance and bioenergetic models, it quantifies waste streams from fed species and their uptake by extractive species (seaweed and shellfish). This calculator supports sustainable Integrated Multi-Trophic aquaculture and circular bioeconomy. For expert guidance, visit Agri Care Hub.
Importance of the Integrated Multi-Trophic Calculator
The Integrated Multi-Trophic Calculator is essential for the future of sustainable aquaculture. IMTA mimics natural ecosystems by co-cultivating fed species (finfish/shrimp) with extractive species that recycle dissolved and particulate wastes. This approach can reduce nutrient discharge by 60–90%, increase total yield by 30–50%, and improve economic resilience. This tool helps farmers design balanced systems, demonstrate environmental benefits, and access sustainability certifications. By integrating feed inputs, growth rates, and nutrient partitioning, it enables precision IMTA aligned with global best practices.
User Guidelines
Using the Calculator is intuitive:
- Select Fed Species: Choose the primary protein source (salmon, shrimp, etc.).
- Enter Biomass: Input current or target biomass of fed species.
- Choose Extractive Species: Select seaweed and shellfish for nutrient recycling.
- Input Feed Data: Provide daily feed rate and FCR.
- Specify System: Enter production cycle and water flow rate.
- Click Calculate: Receive detailed nutrient flows, species ratios, and system performance.
Use real-time farm data for best accuracy. Access resources at Agri Care Hub.
When and Why You Should Use the Integrated Multi-Trophic Calculator
The Integrated Multi-Trophic Calculator is critical in these scenarios:
- System Design: Determine optimal species ratios and spatial layout.
- Environmental Compliance: Quantify nutrient reduction for permits.
- Production Planning: Forecast total harvest and revenue streams.
- Sustainability Certification: Provide data for ASC, BAP, or organic standards.

It is especially valuable for offshore cages, land-based RAS, and coastal pond systems.
Purpose of the Integrated Multi-Trophic Calculator
The primary purpose of the Integrated Multi-Trophic 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:
- Nutrient Excretion: N_out = Feed_N × (1 - Retention) (Chopin et al., 2012).
- Seaweed Uptake: Michaelis-Menten kinetics for DIN and DIP.
- Shellfish Filtration: Clearance rate × particle concentration.
- Biomass Growth: Species-specific FCR and SGR.
Models are validated in Aquaculture, Reviews in Aquaculture, and Marine Ecology Progress Series.
Applications in IMTA Systems
The Integrated Multi-Trophic Calculator supports diverse configurations:
- Offshore salmon + kelp + mussels in cold waters
- Shrimp + Gracilaria + oysters in tropical ponds
- RAS tilapia + Ulva + clams in land-based systems
- Seabass + seaweed rafts + scallops in coastal bays
It is used by governments, NGOs, and industry to scale sustainable Integrated Multi-Trophic aquaculture.
Benefits of Using the Calculator
