Description:
Larval topsmelt (Atherinops affinis) and inland Silversides (Menidia eryllina) were exposed in 96-hr static acute toxicity tests to eleven chemicals to determine the relative sensitivity of the two atherinid species. igh to low LC50 ratios for endosulfan, methoxychlor, carbophenothion, chlorpyrifos, terbufos, fenvalerate, permethrin, 4-nitrophenol, and sodium lauryl sulfate were within a factor of <2 for the two species. . affinis was more sensitive to both azinphos-methyl and, 2,4-dinitrophenol by factors of 6.7 and 4.4, respectively. Comparison of the relative sensitivity of A. ffinis with three freshwater fish species (Lipomas macrochirus, ncorhynohus mykiss, Pimephales promelas) and one estuarine fish species (Cyprinodon variegatus) are also presented. ensitivities were similar between A. affinis and the two most sensitive freshwater species, L. macrochirus and O. mykiss. . affinis is easily transported, cultured and maintained in the laboratory, and readily adaptable for use in toxicological studies.
