Animal Husbandry
Daphnia magna is bred in the LAUS GmbH throughout the year. The animals are kept for the use in toxicity tests. They multiply by parthenogenesis, thus being genetically identical. The keeping is performed similar to the method described in the OECD guideline, following SOP 115 002 01 („Zucht und Hälterung von Daphnia magna STRAUS“), version 12 from 02. Feb. 2015.
Vessels preserving glasses, nominal volume 2 L
Medium M4-Medium (recipe of ELENDT)
Food green algae (Desmodesmus subspicatus)
Medium renewal twice a week
Photo period 16/8 hours, using neon tubes

Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 48 h
Test conditions
- Test temperature:
- 19.6 – 20.1 °C
- pH:
- 7.8
- Dissolved oxygen:
- 8.6mg/l
- Nominal and measured concentrations:
- nominal concentration: 100mg/L
- Details on test conditions:
- Using a glass tube, the daphnia were caught and lifted from the beaker. They were put on a small sieve, and the medium surrounding the animals was sucked off using absorbent paper. Immediately after that, the animals were put into the respective test solution.
The test vessels were left to stand for 48 hours. After 24 and 48 hours, the immobilised daphnia were counted. Daphnia are considered immobilised when they do not perform any movements or are only able to move their antennae when the beaker is gently agitated. Daphnia which are trapped at the surface of the test solution are also considered immobilised.
The pH and the concentration of dissolved oxygen in the test vessels were measured at the beginning and at the end of the test. The content of the test item in the test vessels was measured at the beginning of the test.
