Reproductive Biology of the Female Blue King Crab Paralithodes platypus near the Pribilof Islands, Alaska
Female blue king crabs, Paralithodes platypus, from the Pribilof Islands, were sampled during each of four seasons to determine whether they spawn each year, as do red king crabs, P. camtschatica, or every other year, as reported for Asian blue king crabs. Based on seasonal changes in two indices of...
