Abstract
Increased prey vulnerability was demonstrated for fathead minnows (P. promelas) undergoing acute (24-h) and subacute (21-d) sublethal Cd exposure prior to interacting with largemouth bass (M. salmoides). The lowest acute and subacute Cd concentrations that increased prey vulnerability were 0.375 and 0.025 mg Cd/l, respectively, with the latter well below the maximum acceptable toxicant concentration for fathead minnows. Prey exposed to Cd displayed altered behavior patterns, including abnormal schooling behavior.This publication has 4 references indexed in Scilit:
