Abstract

[Extract] In many freshwater habitats, low dissolved oxygen (DO) is one of the most important and ubiquitous stressors upon aquatic fauna. However, because of an historical focus upon other chemical parameters such as nutrients, salinity and turbidity, and because of the considerable spatio-temporal variability exhibited by DO, its status has rarely been appropriately assessed in the field. Moreover, due to a lack of experimental data on faunal tolerance to low DO (termed hypoxia) water quality guidelines have traditionally provided few insights into the minimum DO requirements of aquatic ecosystems. This project, funded through the Natural Heritage Trust National Competitive Component, aimed to redress this situation by experimentally testing the hypoxia tolerances of a range of freshwater fish species, developing new effect-based water quality guidelines and devising new methods of monitoring DO and assessing the ecological risks associated with DO deficiencies. The current document provides these outputs.
