Acute toxicity of sodium metabisulphite on mangrove crab Ucides cordatus (Decapoda, Ucididae).

The sodium metabisulphite salt is usually used in shrimp culture to prevent black spot. Unfortunately the toxicological effect of this xenobiotic in decapod crabs is unknown. Thus, the present study aims to investigate the sodium metabisulphite LC(50) - 96 h in the mangrove species Ucides cordatus.
