Effect of copper on hatching and development of larvae of the estuarine crab Chasmagnathus granulata (Decapoda, Brachyura)
Ovigerous females of the estuarine crab Chasmagnathus granulata were exposed to 0.05, 0.1, 0.5, and 3 mg/L of copper during the egg incubation period. Regarding egg loss, a higher effect was observed at higher copper concentrations: 80% of the females lost their eggs at 0.5 mg/L, whereas no hatching...
