Seaweed-Integrated RAS Aquaculture

Revolutionary land-based aquaculture system combining fish farming
with natural seaweed water purification

The Challenge: Traditional Aquaculture Limitations

Understanding the environmental and economic barriers in conventional fish farming

💧

Water Pollution

Traditional aquaculture produces massive amounts of nutrient-rich wastewater. Excess nitrogen and phosphorus from fish waste leads to eutrophication, harming local ecosystems and requiring expensive treatment systems.

💰

High Treatment Costs

Conventional water treatment systems require significant capital investment and ongoing operational expenses for filtration, chemical treatment, and waste disposal, reducing farm profitability.

🌊

Resource Inefficiency

Flow-through systems waste valuable water resources and nutrients. Recirculating systems improve efficiency but still struggle with nutrient accumulation and water quality management.

The Aenon Solution: Seaweed-Integrated RAS

A revolutionary closed-loop system that transforms waste into value

Co-Cultivation Innovation

Our system integrates seaweed cultivation directly into the Recirculating Aquaculture System (RAS). Seaweed acts as a living biofilter, naturally absorbing nitrogen, phosphorus, and other nutrients from fish waste while producing oxygen through photosynthesis.

🌿 Natural Purification

Seaweed absorbs dissolved nutrients from fish waste, eliminating the need for chemical treatments and reducing mechanical filtration requirements.

♻️ Zero Discharge

Water continuously recirculates through fish and seaweed tanks, creating a closed-loop system with no environmental discharge.

📈 Dual Revenue

The system produces both high-quality fish and valuable seaweed biomass, creating multiple revenue streams from a single facility.

💡 Energy Efficient

Reduced filtration requirements and natural processes lower energy consumption compared to conventional RAS systems.

How It Works: The Circular System

Water flow and nutrient cycling in our integrated RAS

🐟

Fish Tank

Fish produce nutrient-rich waste (N, P) during feeding and metabolism

🔧

Mechanical Filter

Removes solid particles and suspended matter

🌿

Seaweed Tank

Seaweed absorbs dissolved nutrients, purifies water naturally

💧

UV Disinfection

Final sterilization before water returns

🔄

Recirculation

Clean water returns to fish tank

♻️ Continuous Cycle: Water recirculates 24/7 with >95% efficiency

Target Species & Cultivation Synergy

Optimized combinations for maximum productivity and water quality

🐟 Fish Species

Flatfish (Flounder, Halibut): High-value species ideal for land-based RAS, produce consistent nutrient output
Salmon: Premium market value, moderate nutrient production, optimal growth in controlled RAS
Sea Bass / Bream: Hardy species with good FCR, adaptable to integrated systems

🌿 Seaweed Species

Gracilaria (바다고리풀): Excellent N/P absorption, high growth rate, commercial agar value
Codium fragile (청각): Premium bioactive content, methane reduction compounds, high market value
Sargassum (괭생이모자반): Fast biomass production, cost-effective nutrient removal

🔗 Perfect Synergy

The combination of fish waste nutrients and seaweed absorption creates a balanced ecosystem. Fish provide nitrogen and phosphorus in optimal ratios for seaweed growth, while seaweed maintains water quality for healthy fish development. This symbiotic relationship maximizes productivity while minimizing environmental impact.
