Description
Summary:•L. santolla tolerate up to 60 days without food and high-density of stocking.•Meat quality of L. santolla was not affected by starvation and stocking density.•King crabs can be kept caged at sea in commercial traps for 60 days without mortality.•Starved king crabs showed a very small mass reduction.•L. santolla physiological parameters slightly change during starvation. The southern king crab (SKC) Lithodes santolla is an important commercial species in southern South America. There is a greater need for availability of fresh and live crabs during the season of highest demand in summer (mainly December and January). Thus, this study aimed to determine the effects of starvation and stocking densities on the physiological status of male SKC to know whether SKC can be stocked after they are fished. To assess the effects of starvation, crabs were assigned to two experimental groups: the Laboratory group (in which crabs were either fed daily (controls), fed every 15 days, or starved and the Sea group (in which crabs were either fed every 15 days or starved). Starved crabs showed a very slight mass reduction (
