Technical Bulletin No. 0066: Minimal Oxygen Requirements for Certain Species of Fish

The attached Technical Bulletin was first distributed in 1954. It summarized the results of a study of the minimal oxygen requirements of the common shiner, a warm water fish species, undertaken at the Institute of Paper Chemistry. The project was suggested by the National Council's Wisconsin Kraft Subcommittee, and represented another phase in a broad aquatic biology research program aimed at establishing dissolved oxygen requirements for a variety of fish species and life stages. Of particular interest were the findings concerning the relatively low dissolved oxygen levels that could be tolerated, and the marked effect of temperature on the tolerance level. This Technical Bulletin is being kept in print because the information contained therein continues to be of value in defining suitable environmental conditions for warm water fish species.
