Vaccination with Vibrio anguillarum by oral administration
during copper exposure and intraperitoneal injection prior to copper
exposure was employed to investigate the effects of copper upon survival
and the immune response of juvenile coho salmon (Oncorhynchus
kisutch). Following copper exposure the survivors were challenged
under natural conditions to V. anguillarum,...
Total copper concentrations of 10 [mu]g/l to 100 [mu]g/l appeared to
alter the predator-prey interactions of fathead minnows (Pimephales
promelas) and Daphnia pulex. The effect of copper concentration on
the total amounts of D. pulex consumed over a 12-h period varied with
the density of prey stocked hourly in the...
