| in vivo assessment of the capacity of androstenedione to masculinize female mosquitofish (gambusia affinis) exposed through dietary and static renewal methods. | in this study, we investigated the capacity of androstenedione to masculinize female mosquitofish. previous studies have identified androstenedione in the water and sediment of the fenholloway river, a florida, usa, coastal river that receives paper mill effluent and contains masculinized eastern mosquitofish (gambusia holbrooki). females of the closely related western mosquitofish, gambusia affinis, were exposed to androstenedione through both dietary and static renewal treatments. morphologica ... | 2007 | 17521138 |
| survival time analysis of least killifish (heterandria formosa) and mosquitofish (gambusia affinis) in acute exposures to endosulfan sulfate. | single-species flow-through toxicity tests were conducted to determine the times-to-death of two indigenous fish to south florida--least killifish (heterandria formosa) and mosquitofish (gambusia affinis)--from acute exposure to endosulfan sulfate. mortalities were recorded within 8-h periods from test initiation to termination at 96 h. the 96-h lc(50)s for least killifish and mosquitofish estimated using the trimmed-spearman-karber method were 2.0 and 2.3 microg/l, respectively. an accelerated ... | 2010 | 19921326 |
| acute toxicity and effects analysis of endosulfan sulfate to freshwater fish species. | endosulfan sulfate is a persistent environmental metabolite of endosulfan, an organochlorine insecticide-acaricide presently registered by the united states environmental protection agency. there is, however, limited acute fish toxicity data for endosulfan sulfate. this study determines the acute toxicity (lc₅₀s and lc₁₀s) of endosulfan sulfate to three inland florida native fish species (mosquitofish [gambusia affinis]; least killifish [heterandria formosa]; and sailfin mollies [poecilia latipi ... | 2010 | 21127850 |
