Every single day, a large amount of fish dies from infection such as hyperoxia-induced gas bubble disease consequences by unusual dissolved oxygen (DO) level due to the natural occurrences and human-caused processes of supersaturated water. We are concentrating on the issue of sustainability - an issue of great importance and where this interdisciplinary area has the potential to make a profound impact. We need to step up our game by introducing DO sensing and monitoring at a large scale to overcome this global environmental issue. DO is known as oxygen saturation, one of the most critical parameters in accessing water quality, and necessary to be kept at a sufficient level for the survival of many forms of aquatic biodiversity. Hence, this review article mainly focuses on the potential of optical glass micro-fibre transducers for DO sensing and monitoring, and its contribution toward water security impacts - as part of the Sustainable Goals Development blueprint. The growing body of literature associated with five main work packages i) research motivation of water security, ii) research market analysis discussing the perspective on size, share, growth, trends, and forecast, iii) typical approach on characterising DO level as compared to the optical glass micro-fibre based transducers, iv) conventional design of the optical glass micro-fibre based transducers and v) mechanism of light modulation characteristic in the optical glass micro-fibre based transducers, are highlighted in order to gain a better understanding on the development and progress of optical glass micro-fibre as a transducer for DO sensing and monitoring that can change our life for the better. Finally, several recommendations for future work are presented at the end of this study for the reference of future readers.
