Comparison of azinphosmethyl toxicity to juvenile red drum ( Sciaenops ocellatus) and the mummichog ( Fundulus heteroclitus)
Abstract The acute and sublethal responses of juvenile red drum ( Sciaenops ocellatus ) and mummichogs ( Fundulus heteroclitus ) were evaluated to determine the relative effects of exposure to azinphosmethyl (APM). Acute responses were based on 96‐h static‐renewal bioassays at salinities of 5 and 20...
