Metal bioavailability and toxicity to fish in low-alkalinity lakes: A critical review
Fish in low-alkalinity lakes having pH of 6·0–6·5 or less often have higher body or tissue burdens of mercury, cadmium, and lead than do fish in nearby lakes with higher pH. The greater bioaccumulation of these metals in such waters seems to result partly from the greater aqueous abundances of biologically available forms (CH3 Hg+, Cd2+, and Pb2+) at low pH. In addition, the low concentrations of

Hatching, growth, ion accumulation, and skeletal ossification of brook trout (Salvelinus fontinalis) alevins in acidic soft waters
Brook trout eyed eggs and subsequent alevins were exposed to pH 5.0, 6.5, and 7.0 in soft reconstituted water and to pH 8.2 in hard well water for up to 72 d. Hatching was delayed and hatching success reduced (p < 0.05) in eyed eggs exposed to pH 5.0 and 6.5. Alevin growth was not affected. Fish in all treatments rapidly accumulated monovalent ions in a similar pattern and in the order of Na+ >

Effects of mercury, selenium, and organochlorine contaminants on reproduction of Forster's terns and black skimmers nesting in a contaminated Texas bay
Mean mercury (0.40 mu g/g), and geometric mean DDE (1.6 mu g/g) and polychlorinated biphenyl (PCB) (2.3 mu g/g) concentrations in Forster's tern (Sterna forsteri ) eggs from Lavaca Bay were higher than those in tern eggs from a reference area in San Antonio Bay, but residues were not correlated with hatching success. Nest success was similar between bays. Selenium levels in Lavaca Bay tern e

Metabolism and elimination of benzocaine by rainbow-trout, Oncorhynchus mykiss
1. Branchial and urinary elimination of benzocaine residues was evaluated in adult rainbow trout, oncorhynchus mykiss, given a single dorsal aortic dose of c-14-benzocaine hydrochloride.^2. Branchial elimination of benzocaine residues was rapid and accounted for 59.2% Of the dose during the first 3 h after dosing. Renal elimination of radioactivity was considerably slower; the kidney excreted 2

Development of water level regulation strategy for fish and wildlife, upper Mississippi River system
Water level regulation has been proposed as a tool for maintaining or enhancing fish and wildlife resources in navigation pools and associated flood plains of the Upper Mississippi River System. Research related to the development of water level management plans is being conducted under the Long Term Resource Monitoring Program. Research strategies include investigations of cause and effect relati

Rotenone persistence in freshwater ponds: Effects of temperature and sediment adsorption
The persistence of rotenone was compared between a cement-lined pond (0.04 hectare) and an earthen-bottom pond (0.02 hectare) treated with 5 I?L Noxfish/L (250 I?g rotenone/L) during spring, summer, and fall. Water temperatures on the days of treatment in each season were 8, 22, and 15A?C, respectively. Both ponds were filled with pond water from a common source 1 week before each of the three tre

Benzocaine as an anesthetic for striped bass
Benzocaine was tested as an anesthetic on juvenile and mature adult striped bass (Morone saxatilis ). Concentrations of 55 mg/L at 22 degree C to 80 mg/L at 11 degree C effectively anesthetized fish in about 3 min. Recovery was more rapid as temperature increased. Fish survived concentrations of twice the effective concentration and exposure times up to 60 min at the effective concentration. St

Contaminant exposure of willets feeding in agricultural drainages of the lower Rio Grande valley of south Texas
Willets (Catoptrophorus semipalmatus) were collected in June and August 1986 at the outlets of two agricultural drainages into the Lower Laguna Madre of South Texas and at two other Texas coastal sites. Mean liver concentration of arsenic was higher in August than June. Over 20% of the livers had arsenic concentrations elevated above a suggested background level of 5.0 ppm dry weight (DW), but con
