Effect of aerial exposure on the antioxidant status in the subantarctic stone crab Paralomis granulosa (Decapoda: Anomura)
In Tierra del Fuego (Southern South America), the stone or false king crab, Paralomis granulosa represents one of the most important crabfisheries. After capture, animals are kept in baskets and exposed to dryness for several hours, when the water flow through the gills is interrupted.As a consequen...
