SRAC-Based RAS System Calculation for Aquaculture Design

This RAS (Recirculating Aquaculture System) calculation tool is developed based on the guidelines and standard formulas of the Southern Regional Aquaculture Center (SRAC), combined with real-world engineering experience from CADSON Engineering & Services. It ensures accurate, practical, and industry-ready design outputs for aquaculture and fish farming projects.

How This RAS Calculation Tool Helps Your Project

This RAS (Recirculating Aquaculture System) calculation tool helps engineers, fish farmers, and investors quickly determine the core design parameters of an aquaculture system. By entering basic input values, users can estimate tank volume, fish biomass, feed rate, and water quality requirements.

The tool also calculates TAN (Total Ammonia Nitrogen) production and biofilter sizing, which are critical for maintaining a stable and healthy aquatic environment. These calculations are essential for designing an efficient, sustainable, and scalable fish farming system.

Key Parameters Calculated

Tank Size and Total System Volume

Fish Biomass and Stocking Density

Feed Rate (Daily and Percentage)

TAN (Total Ammonia Nitrogen) Production

Biofilter Capacity and Efficiency

Water Flow Rate and Exchange Requirements

Applications of RAS Calculation

This calculator is suitable for:

• Commercial Fish Farming Projects
• Small and Medium Scale Aquaculture Farms
• Research and Training Institutes
• Aquaculture System Design Engineers
• Investment Feasibility Studies

Why Accurate RAS Calculation is Important

Accurate calculation is the foundation of a successful RAS project. Incorrect estimation of biomass, TAN, or biofilter size can lead to poor water quality, fish stress, and system failure.

Using a scientifically validated calculation method based on SRAC guidelines ensures that your aquaculture system is properly balanced, energy-efficient, and capable of long-term operation.
