Despite the widespread use of Daphnia magna as a test organism in bioassay studies, little
attention has been devoted to conditions necessary for culturing healthy animals in the …

ABSTRACT; The purpose of this paper is to review the literature and to discuss the use of
Daphnia in toxicity tests in the context of what we understand about its biology. For example …

Daphnia magna (Straus) is a small planktonic crustacean which is widely distributed in
ponds and lakes in Ontario, and is representative of filter-feeding zooplankton communities …

The Daphnia 21‐d juvenile production test was ring tested in 1985. The results showed
maximum variability, that is, the effective concentration ranged from less than the lowest …

Chronic toxicity tests with Daphnia magna are proposed in both the Toxic Substances
Control Act in the USA and under the 6th Amendment of the 1967 Directive of the EEC on …

Acute toxicity tests were performed with six age groups of Daphnia magna. ranging from< 6
h to 216 h, and with five chemicals, selected on the basis of their physical and chemical …

Zooplankton are an important part of the aquatic ecology of all lakes and streams. As a
result, numerous methods have been developed to assess the quality of waterbodies using …

A new high-hardness (HH) COMBO medium for long-term culturing and bioassay testing
ofDaphnia magnawas evaluated in 21-day survival, growth, and reproduction studies. The …

Daphnia magna is used widely as a standard ecotoxicological indicator organism, and
protocols exist for its use in assessing the toxicity of substances under acute and chronic …

One of the most internationally used bioassays for toxicity screening of chemicals and for
toxicity monitoring of effluents and contaminated waters is the acute toxicity test with daphnid …
