Researchers with the Alaska Fisheries Science Center (AFSC) at the Kodiak Lab are currently studying the embryonic and larval development of golden king crabs as well as the effects of temperature and density on survival and growth of larvae. The male crab, or jimmy, has blue claws and an underside "apron" which looks like an upside-down T or the "Washington Monument."

The male clasps unto the female’s carapace for days, and after molting has occurred, the male can finally fertilize the female’s clutch of 50,000 to 500,000 eggs. Golden king crabs live in the deepest depths, around 1500 feet. Adult crabs tend to segregate by sex once off the mating/molting grounds. The primary fishery for golden king crab occurs in the Aleutian Islands – with localized areas in the Bering Sea and Gulf of Alaska accounting for only minor catches. That operates on a special Commissioner’s Permit and this year it also used a 30,000 pound test fishery to get data on Tanners in untapped reaches of the Sound. [2] Golden king crabs were historically caught incidentally in red king crab fisheries, but the first commercial landing took place in 1975; in 1981, the targeted pot-fishing method, a hybrid fishing method specifically for golden king crab, was developed.
