Evaluation of the toxicity and efficacy of hydrogen peroxide treatments on eggs of warm- and coolwater fishes Evaluation of the toxicity and efficacy of hydrogen peroxide treatments on eggs of warm- and coolwater fishes
The use of hydrogen peroxide in aquaculture is growing and there is a need to develop fundamental guidelines to effectively treat diseased fish. The safety (toxicity) of hydrogen peroxide treatments was determined on eggs of representative warm- and coolwater fish species. Eggs of northern pike (Esox lucius), walleye (Stizostedion vitreum), yellow perch (Perca flavescens), white sucker...

Effects of immobilization by electricity and MS-222 on brown trout broodstock and their progeny Effects of immobilization by electricity and MS-222 on brown trout broodstock and their progeny
To determine the effects of electrically and chemically induced immobilization on postspawn broodstock and their progeny, age‐2 and age‐3 female broodstock and age‐2 male broodstock of brown trout Salmo trutta were immobilized with electricity or tricaine methanesulfonate (MS‐222), stripped of their eggs or milt, and weighed. Eggs taken from electrically immobilized females were...

Toxicity of hydrogen peroxide treatments to rainbow trout eggs Toxicity of hydrogen peroxide treatments to rainbow trout eggs
Hydrogen peroxide treatments of 0, 500, 1,000, and 3,000 I?L/L, concentrations that were multiples of the Low Regulatory Priority limit of 500 I?L/L, were administered for 15 min every weekday (Mondaya??Friday) to eggs of rainbow trout Oncorhynchus mykiss and steelhead (anadromous rainbow trout) to determine the margin of safety existing for standard egg treatments. All untreated and...

Importance of analytically verifying chemical treatments Importance of analytically verifying chemical treatments
Hydrogen peroxide is considered a low regμLatory priority compound by the U.S. Food and Drug Administration. It is used to control fungal infections on fish eggs. We studied the treatment profiles of hydrogen peroxide in Heath, McDonald egg jar, and Clark–Williamson incubators during treatments intended to deliver an effective regimen of at least 500 μL hydrogen peroxide/L (i.e...

Toxicity of fire retardant chemicals to aquatic organisms: Progress report Toxicity of fire retardant chemicals to aquatic organisms: Progress report
Fire retardants and suppressants used extensively in North America are often applied in environmentally sensitive areas that may contain endangered, threatened, or economically important plant and animal species. We conducted laboratory acute toxicity tests in both hard and soft waters with five commonly used fire control chemicals (Fire Trol LCG-R, Fire-Trol GTS-R, Phos-Chek D-75-F...

Acute toxicity of three fire-retardant and two fire-suppressant foam formulations to the early life stages of rainbow trout (Oncorhynchus mykiss) Acute toxicity of three fire-retardant and two fire-suppressant foam formulations to the early life stages of rainbow trout (Oncorhynchus mykiss)
Laboratory studies were conducted with five early life stages of rainbow trout, Oncorhynchus mykiss, to determine the acute toxicities of five fire-fighting chemical formulations in standardized soft and hard water. Eyed egg, embryo–larvae, swim-up fry, and 60- and 90-d posthatch juveniles were exposed to three fire retardants (Fire-Trol LCG-R, Fire-Trol GTS-R, and Phos-Chek D75-F) and...
