Crayfish equipped with high-tech sensors have been drafted in by a Czech brewery in its quest to keep their water supply pure.
配有高科技感測器的小龍蝦，被捷克一家釀酒廠徵召來維持他們所追求之供水系統潔淨。
The Protivin brewery in South Bohemia has placed the creatures, which react quickly to changes in their aquatic environment, in fish tanks through which is pumped water from the same natural source that the brewery uses.
位於南波希米亞州的普羅蒂溫釀酒廠，把這些快速因應水生環境變化的生物放進大型魚缸裡，魚缸抽的水和酒廠用的水來自相同天然泉源。
The animals are fitted with infrared bio-sensors which monitor their heartbeat and movement. Data is analyzed by a computer, and any changes in the animals’ body or behavior flags a change in the purity levels of the water in its tank.
這些動物裝有監測牠們心跳與動作的遠紅外線生物感測器。數據由電腦分析，該動物體內或行為的任何變化，象徵了缸中水質純淨度的變化。
“When three or more crayfish are moving or change their pulse activity, we know that the water parameters have changed. We can react quickly because we have the result within three minutes,” head brewer Michal Voldrich told Reuters.
釀酒領班米恰．沃爾德日赫告訴路透：「當3隻以上小龍蝦移動或脈動改變，我們就知道水質參數有異。我們可以迅速反應，因為我們3分鐘內就知道結果。」
