Available in PDF, EPUB and Kindle. Book excerpt: Selected freshwater invertebrates of various trophic levels are grown at the Freshwater Institute for studying basic physiological and nutritional relationships, effects of toxic materials on morphological and physiological phenomena and effects of continued laboratory culture on population dynamics, physiology and morphology, tetrahymena vorax, helisoma trivolvis, Artemia sp., Daphnia magna, D. pulex, Hyalella azteca, Gammarus lacustris lacustris, Orconectes virilis, Chironomus tentans and Hexagenia rigida have been cultured. Procedures for culturing organisms on various nutritional bases are outlined. Techniques such as storage of partly developed eggs or over-wintering animals, artificial insemination of insect egg masses, washing procedures and production of given life phases specifically for use in toxicological studies are described. Methods for collecting and transporting organisms from the field are outlined. Specific environmental preferences, diseases and parasites and geographic distribution are described.
