ACCLIMATION

- Feeding frequency during acclimation: three times per week or daily until 24 hours before the test was started
- Health during acclimation (any mortality observed): During the last 7 days prior to the start of the test no fish died in the test fish batch. Therefore the mortalities in the fish batch were below 5% and the fish batch was accepted.

Analytical Results:
In the freshly prepared test media at the start of the test and at the renewal of the test media 106% of the nominal test concentrations were found. In the 24 hour old test media after 24 and 96 hours test duration, also a measured concentration of 106% of the nominal value was determined. During the test the test organism were exposed to a mean of 106% of nominal.
Table 1: Validity criteria of the study
Criterion from the guideline
Outcome
Validity criterion fulfilled
The mortality in the control(s) should not exceed 10% (or one fish if less than ten are used) at the end of the test
No mortality was observed
Yes
The dissolved oxygen concentration must have been at least 60 per cent of the air
saturation value throughout the test
>93%
Yes
There must be evidence that the concentration of the substance being tested has been
satisfactorily maintained, and preferably it should be at least 80 per cent of the
nominal concentration throughout the test. If the deviation from the nominal
concentration is greater than 20 per cent, results should be based on the measured
concentration.
106%

Additional information
One experimental study is available investigating the toxicity of the test item sodium anisate (CAS 536-45-8) to fish . The study was conducted according to OECD 203 (GLP) using the rainbow trout Oncorhynchus mykiss under semi-static conditions. The test was performed according to the thresholdapproach OECD 126. The absence of mortality at 100 mg/L indicated that fish was not the most sensitive group of test organisms and that the LC50 is greater than the limit test concentration. The measured content of the test item in the fresh as well as in aged test solution was 106% of nominal. Since the content of active ingredient in the samples was between 80 and 120% of nominal, the toxicological endpoints were evaluated using nominal test item concentrations. The LC50 (96 h) of the test item was determined to be > 100 mg/L test item (nominal). The corresponding NOEC (mortality) (96 h) was 100 mg/L test item (nominal).No sublethal effects were observed in the control and test item concentration 100 mg/L after 96 h.
