This review provides a synopsis of information available on the geographical distribution, identification, natural history and reproductive habits of the topsmelt, Atherinops affinis. We also review and report on procedures for laboratory spawning of adult topsmelt, culturing of the early-life stages including embryos and larvae, and conducting several different toxicity tests with early-life stages. The toxicological protocols were developed as part of a continuing effort by the U.S. Environmental Protection Agency and the California Water Resources Control Board to provide toxicity testing protocols for indigenous indicator fishes that can be used in pollution research and effluent monitoring programs in the Pacific coastal region of the United States.
