Lethal and sublethal responses to the herbicides 2,4-D, DEF, propanil, and trifluralin of various life history stages of the Dungeness crab, Cancer magister, were examined to estimate maximum acceptable toxicant concentrations (MATC) of each compound for this species. Zoeae were found, in long term tests, to be the most sensitive stage. Based on the experiments with this stage, MATCs were concluded to be greater than 0.95, less than 6.9 micro g/L for DEF, = 26, less than 220 micro g/L for trifluralin, = 80, less than 1,700 microgram/L for propanil, and less than 1,000 micro g/L for the free acid form of 2.4-D.
