Seawater carbonate chemistry and biological indices and oxidative stress responses of marine crab Scylla serrata to the impact of ocean acidification and cadmium toxicity

In the current study, the effect of OA on the toxicity of cadmium (Cd) in the crab Scylla serrata was evaluated. Crab instars (0.07 cm length and 0.1 g weight) were subjected to pH 8.2, 7.8, 7.6, 7.4, 7.2, and 7.0 with and without 0.01 mg l−1 of Cd for 60 days.
