Alternatives to animal testing development of non-animal test methods. Laboratory animals are not restricted to rats, mice, dogs, and rabbits, but also include fish, frogs and birds. Research into alternatives to replace these species is often neglected, although fish are the third most widely used laboratory animal used for scientific purposes in the EU. This is also the field where until now only two alternative tests exist worldwide: One guideline, OECD TG 236, and one guidance (OECD series on testing and assessment 126) are so far available. Euroecotox is a European network for alternative testing strategies in ecotoxicology. It was funded by the Seventh
