eelfiltratsioon

Eelfiltratsioon, also known as eel filtration, refers to the process of removing fine particles, debris, and microorganisms from water using specialized filters designed to accommodate eel-like organisms. This technique is commonly employed in aquaculture, particularly in the breeding and rearing of eel species such as the European eel (*Anguilla anguilla*) and the American eel (*Anguilla rostrata*). The goal is to maintain water quality while ensuring the health and safety of the eels, which are sensitive to poor water conditions.

The filtration process typically involves mechanical, biological, and sometimes chemical methods. Mechanical filtration uses materials like fine mesh screens, foam pads, or ceramic filters to trap solid particles. Biological filtration relies on beneficial bacteria, often housed in media such as bio-balls or gravel, to break down organic waste into less harmful substances. In some cases, chemical filtration, such as activated carbon, may be used to remove toxins or odors.

Eelfiltratsioon systems are designed to be gentle to avoid damaging the delicate skin or gills of eels, which can be easily injured by rough filtration surfaces. The water flow must also be carefully controlled to prevent stressing the eels. Proper maintenance, including regular cleaning and replacement of filter media, is essential to prevent clogging and ensure efficient operation.

This process is particularly important in closed or recirculating aquaculture systems (RAS), where water is continuously reused. Effective filtration helps sustain a stable aquatic environment, reducing the risk of disease and improving growth rates. Additionally, eelfiltratsioon contributes to sustainability by minimizing water waste and chemical usage in eel farming operations.
