摘要: This study evaluated the acute toxicity of copper at different life stages freshwater prawn, Macrobrachium rosenbergii, to determine effect sublethal concentration on osmoregulatory capacity (OC), measure level in gills, and investigate histological change gills adult prawns. The 24-, 48-, 96-h medium lethal (LC50) M. rosenbergii increased progressively along with increasing stage, from postlarvae, juvenile adult. LC50 values for were higher 0 ppt than those 12 both After 7 d exposure 0.75 mg Cu L−1 ppt, OC exposed prawns reduced by 47%, respectively, compared control animals. However, value 0.5 mg Cu L−1 was not significantly ppt. concentrations gill tissues significa...
