Abstract
Laboratory tests were conducted to determine the acute toxicity of dithiocarbamates (Aquatreat and Busan) to molting grass shrimp and the effects of these fungicides on regenerative limb growth in grass shrimp. Results indicate that both dithiocarbamate formulations caused a dose-related inhibition or regenerative limb growth in grass shrimp. The number of days to molting was not significantly altered by Aquatreat or Busan-exposure, indicating that dithiocarbamates primarily exert their effects on the developing limb bud tissue rather than through the neuroendocrin system. Toxicity tests on Aquatreat DNM-30 (96 h LC50:127 ppb) and Busan 85 (96 h LC50: 49 ppb) revealed that dithiocarbamates are toxic to molting grass shrimp.
