Test organisms

Test organisms (species):
Oncorhynchus mykiss (previous name: Salmo gairdneri)
Details on test organisms:
The toxicity study was run using the species Rainbow trout (Salmo gairdneri).
The tests were run with Rainbow trout supplied by P. Hohler Forellenzucht, CH-4314 Zeiningen/Switzerland. The average fish weight, determined at the start of the test ranged between 1.0 - 1.3 g. The fish size was not measured, due to mistake by personnel.
