| 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 |
| effects of salinity on native estuarine fish species in south florida. | variable and high salinities have been identified as key stressors in florida bay. the comprehensive everglades restoration plan (cerp) includes water redistribution projects that are intended to restore natural freshwater flows to northeastern florida bay. the present salinity regimes in the area, which span from hypo- to hypersaline, will be altered as a result of these actions. this research examined biological performance measures (i.e., growth and survival) of estuarine fish under varying s ... | 2008 | 18642076 |
| using data from an encounter sampler to model fish dispersal. | a method to estimate speed of free-ranging fishes using a passive sampling device is described and illustrated with data from the everglades, u.s.a. catch per unit effort (cpue) from minnow traps embedded in drift fences was treated as an encounter rate and used to estimate speed, when combined with an independent estimate of density obtained by use of throw traps that enclose 1 m(2) of marsh habitat. underwater video was used to evaluate capture efficiency and species-specific bias of minnow tr ... | 2011 | 21284631 |
