Challenges in Carp Farming Today
Carp farming remains a vital sector in global aquaculture, especially across Asia and Eastern Europe. However, traditional pond-based systems often face challenges such as water pollution, poor disease control, and inefficient resource use. With the rising need for sustainable and scalable solutions, Recirculating Aquaculture Systems (RAS) are becoming an increasingly popular choice for modern carp farming operations.

What Is RAS?
RAS (Recirculating Aquaculture System) is a land-based fish farming system that reuses water after mechanical and biological filtration, making it a highly water-efficient and controllable solution. A typical RAS includes:
√ Mechanical Filtration: Removes suspended solids and fish waste
√ Biological Filtration: Converts harmful ammonia and nitrites into less toxic nitrates
√ Aeration and Degassing: Ensures adequate oxygen levels while removing CO₂
√ Disinfection: UV or ozone treatment to minimize disease risk
√ Temperature Control: Keeps water temperature optimal for fish growth
By maintaining optimal water quality, RAS allows for high stocking density, lower disease risk, and reduced water usage, making it ideal for sustainable carp farming.
RAS Requirements for Carp Farming
Carp are resilient fish, but successful intensive farming still depends on stable water quality. In a RAS setup, the following factors are particularly important:
√ Water Temperature: Generally 20–28°C for optimal growth
√ Dissolved Oxygen: Must be kept at sufficient levels for active feeding and metabolism
√ Ammonia and Nitrite Control: Carp are sensitive to toxic nitrogen compounds
√ Tank and System Design: Should consider the active swimming behavior and biomass load of carp
Given their long grow-out cycle and high biomass, carp farming demands reliable equipment and efficient sludge management.
