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.

Sediment contamination is a widespread environmental problem that can potentially pose a threat to a variety of aquatic ecosystems. The sediment test methods in this manual will be used by The United States Environmental Protection Agency (USEPA) to make decisions under a range of statutory authorities concerning such issues as: dredged material disposal, registration of pesticides and toxic substances, superfound site assessment, and assessment and cleanup of hazardous waste treatment, storage, and disposal facilities. The use of uniform sediment testing procedures by USEPA programs is expected to increase data accuracy and precision, facilitate test replication, increase the comparative value of test results, and ultimately, increase the efficiency of regulatory processes requiring sediment tests.

Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.

"Freshwater Aquaculture" is the definitive guide to freshwater aquaculture, an indispensable resource for both professional aquaculturists and backyard fish growers. William McLarney, scientist and pioneer in the field, describes every aspect of aquaculture, from the underlying scientific concepts to stepby- step instructions for each type, size, and phase of culture. Numerous species are discussed in detail, from catfish and trout to freshwater shrimp and clams. The emphasis throughout is on energy efficiency and ways to work profitably within natural ecosystems. Using numerous tables, hints, and details of how and how not to do it, McLarney proves fish culture need not be hit or miss, with endless trial and error, financial losses, and discouragement to the prospective farmer. Nothing has been overlooked in this guide. As well as providing all the basic information on the culture of North American freshwater food fishes, the author has explained the various aquaculture systems, including those integrated with plants, land animals, and cage cultures. Pond construction and repair, water quality and chemistry, marketing and shipping concerns, diseases, and legal restrictions are all explored. "Freshwater Aquaculture" includes cooking methods for the different species as well as a large appendix describing qualities such as habitat, ease of culture, and flavor of the thirty-five food fishes discussed. A thorough resource section provides valuable information on publications, supplies, advice, and training.

Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.
