- Title
A NEW METHOD OF STUDYING THE REACTIONS OF FISHES IN STABLE GRADIENTS OF CHEMICAL AND OTHER AGENTS.
- Authors
Höglund, Lars B.
- Abstract
A new method is described, the fluviarium method, for studying the responses of water-animals to graded conditions mainly with regard to chemical agents. The method of producing gradients is outlined and their reproducibility and stability determined. Some experiments with inorganic salts and dissolved oxygen are described as exemplifications. The conception of the "preference threshold value" for experimentally tested agents. required for the treatment of experimental data of this type is defined and discussed and placed in relation to the earlier terms minimum perceptible and minimum distingibile.
