Evaluation of p,p'-DDT as a reference toxicant in bioassays Evaluation of p,p'-DDT as a reference toxicant in bioassays

p,p'-DDT was tested as a reference standard toxicant against 19 species of freshwater fish, including 39 lots from 10 sources. In particular, the rapidity, nonselectivity, and consistency of its toxicity to fish were evaluated in 96-hour static bioassays. The chemical was rapidly and consistently toxic to lake trout, carp, green sunfish, bluegill, and yellow perch. It lacked either rapid...

Some blood chemistry values for five Chesapeake Bay area fishes Some blood chemistry values for five Chesapeake Bay area fishes

Blood samples from gizzard shad,largemouth bass, white perch, pumpkinseed, and toadfish were analyzed for hemoglobin, total plasma protein, total plasma cholesterol, and ion concentrations of plasma sodium, potassium, and chloride. The hemoglobin concentration and total plasma cholesterol found in a given species seem to have positive correlation with the customary activity level of that...

Some effects of sublethal concentrations of sodium arsenite on bluegills and the aquatic environment Some effects of sublethal concentrations of sodium arsenite on bluegills and the aquatic environment

Bluegills were exposed to sodium arsenite at various concentrations and treatment frequencies in outdoor pools. The effects of the treatments on the fish and invertebrates in the pools were assessed. Applications totaling 4.0 ppm or more of NaAsO2 during the experiment were reflected in reduced survival and growth of the fish, with immature fish being affected to a greater degree than...
