Laboratory bioassays on the blue shrimp (Penaeus stylirostris) were conducted with Cutrine-Plus, a chelated copper algicide registered for use in fish hatcheries but not for shrimp culture facilities. The 24- and 96-h LC50’s for blue shrimp were found to be 151.3 and 19.5 mg/L copper as Cutrine-Plus, respectively. Cutrine- Plus was found to be safe (i.e., produced no statistical mortality) at a use rate of 1.0 mg/L for a 24-h static exposure. The 24-h EC50 for gill melanization was 0.64 mg/L copper. In residue studies no accumulation of copper in whole-body tissue due to the treatments could be shown.
