Planar PCB Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Planar PCB Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Ecological and toxicological aspects of polychlorinated biphenyls (PCBs) in the environment are reviewed with emphasis on biologically active congeners and fish and wildlife. Subtopics include sources and uses, chemical and biochemical properties, concentrations in field collections, lethal and sublethal effects, and recommendations for the protection of sensitive resources. All...

Feeding ecology of larval and juvenile American shad (Alosa sapidissima) in a small pond Feeding ecology of larval and juvenile American shad (Alosa sapidissima) in a small pond
Release ponds are used as part of a multifacet effort to restore American shad (Alosa sapidissima) in the upper Susquehanna River basin. Little information exists, however, on the feeding ecology of young shad in small ponds. Consequently, we examined feeding ecology and prey selection of 299 larval and 299 juvenile American shad in a small pond during spring and summer. Larval shad...

Control of external Aeromonas salmonicida: topical disinfection of salmonids with Chloramine-T Control of external Aeromonas salmonicida: topical disinfection of salmonids with Chloramine-T
Brook trout Salvelinus fontinalis were treated with single 60-min static baths of 250 mg formalin/L, 3% NaCl, and 15 mg Chloramine-T/L to evaluate the efficacy of these compounds against external infections of Aeromonas salmonicida. Prevalence of A. salmonicida was significantly lower in brook trout treated with Chloramine-T than among those treated with formalin or salt. Further...

Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards
The toxicities of seleno-l-methionine, seleno-dl-methionine, and selenized yeast were compared. Ten pairs of mallards were fed a control diet and 15 pairs were fed diets containing 10 ppm selenium as seleno-dl-methionine, seleno-l-methionine, or selenized yeast. Hatching of fertile eggs was significantly lower for females fed 10 ppm selenium as seleno-dl-methionine (7.6%) and seleno-l...
