Fish can respond not only to acutely toxic conditions in the water, but also to the presence of chemical carcinogens. Fish develop neoplasms in response to many known mammalian carcinogens (NCI, 1984; Couch and Harshbarger, 1985). Studies have been conducted with freshwater and brackish-water species to evaluate their sensitivity to carcinogens. The freshwater Japanese medaka and guppy (king cobra strain), and to a lesser extent the brackish-water sheepshead minnow, proved to be the most susceptible.

Observational studies —including outbreak investigations, analytic epidemiologic investigations, and in situ studies—are reviewed and illustrated for each population of food animals, companion animals, and fish and wildlife. The use of animal sentinel systems specifically in risk assessment is considered in Chapters 6 and 7. They focus on selection and application of animal sentinels for components of qualitative and quantitative risk assessment. As requested in the committee's task, some discussion of application of animal sentinel data to geographic information systems methods is included.
