Using peer-reviewed biophysical models, it integrates temperature, salinity, light, and nutrient dynamics to deliver accurate yield forecasts for pond, tank, and offshore systems. This calculator supports sustainable Gracilaria Yield optimization and agar industry planning. For expert resources, visit Agri Care Hub.
Importance of the Gracilaria Yield Calculator
The Gracilaria Yield Calculator is essential for the sustainable development of the red seaweed industry. Gracilaria is the primary source of agar, a critical hydrocolloid used in food, microbiology, and pharmaceuticals. Global demand for agar is rising, with Gracilaria farming expanding in tropical and subtropical regions. This tool helps farmers optimize stocking density, predict harvest timing, estimate agar yield, and plan processing inputs. By modeling photosynthesis, nutrient uptake, and environmental responses, it enables precision aquaculture aligned with FAO and ICES best practices.
User Guidelines
Using the Gracilaria Yield Calculator is intuitive:
- Select Species: Choose from major cultivated Gracilaria species or "Custom" for user-defined parameters.
- Enter Area and Density: Input cultivation area and initial wet biomass per square meter.
- Input Growth Data: Provide growth cycle, water temperature, salinity, and light intensity.
- Specify Moisture: Enter harvest moisture content (typically 85–90%).

Purpose of the Gracilaria Yield Calculator
The primary purpose of the Gracilaria Yield Calculator is to bridge scientific research and on-farm application. By translating complex ecophysiological models into a user-friendly interface, it empowers smallholder and commercial farmers to achieve higher productivity, lower risk, and greater environmental impact. This tool supports the global transition to regenerative aquaculture and circular bioeconomy systems.
Scientific Foundation of the Calculator
All calculations follow peer-reviewed methodologies:
- Photosynthetic Growth: SGR = f(T, S, I, N) based on Michaelis-Menten kinetics (Yong et al., 2013).
- Temperature & Salinity: Optimal ranges with Q₁₀ and salinity tolerance curves.
- Agar Content: 15–30% of dry weight, species-dependent (Kim et al., 2017).
- Nutrient Uptake: V_max and K_m from tissue analysis.
Models are validated in Aquaculture, Journal of Applied Phycology, and Algal Research.
Applications in Gracilaria Cultivation
The Gracilaria Yield Calculator supports diverse systems:
- Pond culture in tropical coastal areas
