OXYGEN CONSUMPTION, AMMONIA EXCRETION AND 0:N ATOMIC RATIO DURING THE FIRST LARVAL STAGE OF THE SOUTHERN KING CRAB LITHODES SANTOLLA FROM TIERRA DEL FUEGO, ARGENTINA

摘要

The Southern King crab, Lithodes santolla, is the most important shellfish in Beagle Channel, Tierra del Fuego, Argentina. Larval development involves three larval stages, during a period comprising 6 to 7 days each one, in experimental conditions andone postlarval glaucothoe stage. Previous studies on larval culture and chemical composition during larval development have been made (Comoglio et al, 1991; Lovrich et al, 2003). This study attempts to evaluate physiological parameters during the firstlarval stage.
