Recirculating Aquaculture Systems (RAS): A Growing Trend in Romanian Fish Farms

Recirculating Aquaculture Systems (RAS) are becoming an increasingly attractive solution for fish farms in Romania, in the context of climate change and rising demand for fresh fish. These systems allow strict control of water quality and significantly reduce resource consumption, achieving up to 90% efficiency in water reuse.

According to the Romanian Aquaculture Association, the initial investment in a RAS farm ranges between €500,000 and €1.5 million, depending on capacity. The economic yield is highly attractive: annual production can exceed 100 kg per cubic meter of water, far surpassing traditional systems.

In 2024, Romania had approximately 20 farms using RAS, and the trend is upward thanks to European Union support dedicated to aquaculture. Profitability is also supported by higher prices obtained for premium fish species such as African catfish, trout, and sturgeon.

The main challenges remain access to financing, lack of know-how, and high energy costs. Nevertheless, experts estimate that over the next five years, the number of RAS farms could double, significantly contributing to the reduction of the domestic fish deficit.
