Fibre-optic technology to benefit aquaculture: Portuguese team develops new C02 sensors

摘要

Monitoring water quality is relevant in a lot of fields: the determination of dissolved carbon dioxide levels (dCO_2) related to global warming and ocean acidification is in the order of the day, but has applications in other fields, namely intensiveaquaculture. Fish and bacteria in culture systems respire, producing CO_2, an excess of which reduces the fishes capacity to use oxygen, thus inducing stress and reducing growth.
