Fish-PhotoCAT - Photocatalytic water remediation for sustainable fish farming

About Us

The project aims at investigating the efficiency of a smart purification system to improve water quality, fish production and environmental sustainability in aquaculture systems, through the remediation of nitrogen containing compounds in water and the biocidal action of a TiO2-based photocatalytic treatment. In detail, the project aspires to develop an innovative photocatalytic reactor, by modifying the traditional filters used in aquaculture, to obtain a new low cost generation filter for fresh and sea water purification. This innovation, consisting in the application of plates covered with a TiO2 photocatalytic film in front of the UV lamps already installed for sanitization in the tanks for aquaculture, will largely increase the effects of lamp irradiation.

Period of Implementations

Dec 1, 2020 - Nov 30, 2023

Total Budget

EUR 707.572,60



 lowering the nitrogen containing compounds produced by fish farms  further reducing bacteria and viruses, thus improving fish health and vitality  lowering the mortality rate and thus the carcasses disposal costs and the CO2 environmental impact  mitigating the emission of ammonia and greenhouse gasses into the atmosphere from the water surface


Proposal shall contribute to the making of a technological friendly- environment innovation for small scale fish farmers or small holders.

Impact Pathway

Additional economic benefits thanks to the reduction of fish mortality and the lower related discharging costs, in economic and lower CO2 production terms.
