Unfed lecithotrophic larvae of the golden king crab Lithodes aequispinus were reared at 3, 6, and 9degreeC in darkness and 33-34 ppt salinity. This study was done to improve our understanding of larval development time and the ability of the larvae to survive under different seasonal thermal conditions. The survival rates and intermolt duration was observed for the first zoeal molt (ZI), second molt (ZII), third molt (ZIII), and glaucothoe (G). The duration from hatching to the start of the first nonlarval stage (crab I) averaged 148. 94, and 75 days at 3, 6, and 9degreeC, respectively.
