Aquatic Organisms
ECT offers a wide range of aquatic ecotoxicological standard tests under GLP according to OECD and ISO guidelines. This includes tests with aquatic micro-organisms, algae, higher plants, crustaceans, insects and fish. Our standard species in fish tests are zebrafish (Danio rerio), fathead minnow (Pimephales promelas) and rainbow trout (Oncorhynchus mykiss). We can adapt test designs to the specific requirements of a test substance. In addition, we further develop and conduct tests with non-standard test species and multi-species test systems, and we are familiar with species sensitivity distributions.
