Chronic toxicity of metals in two water hardness to three sizes of the crayfish Faxonius quadruncus Missouri, USA 2017-2018

Laboratory studies were conducted to examine the effect of water hardness and age of crayfish on the toxicity of environment-based metals mixture. Additionally, the effects of chronic exposure to a metals mixture to egg development in adult F. quadruncus were assessed. Mortality and growth of F. quadruncus were assessed. These data consist of attributes of water quality from toxicity tests and attributes of growth and survival of crayfish (F. quadruncus) from laboratory diluter studies.
