ABSTRACT Examination of deep-water female golden crabs collected monthly from the southeastern coast of Florida indicates an annual reproductive cycle with a single batch of eggs produced each year. Oviposition begins in late August and continues through October with eggs retained for approximately 6 months until hatching during late February and March.

Commercial crab populations off the Kamchatka coasts are infested to a considerable degree by the rhizocephalan parasite Briarosaccus callosus: of 769 Lithodes aequispina males examined, 43 (5.7%) were parasitized. Infestations result in the feminization of the crabs, a significant decrease in the cheliped length, and a significant decrease in the ...

Effect of data weighting on the mature male biomass estimate for Alaskan golden king crab
Fisheries Research, 2017Abstract Size-structured integrated population dynamics models are used to estimate the time-trajectories of mature male biomass (MMB) of Alaska crab stocks for stock status determination and harvest allocation. Lack of annual biomass surveys makes it difficult to assess the status and biomass of the Aleutian Islands golden king crab ( Lithodes ...

Fish eggs and larvae of the genus Careproctus were found in the gill chamber of ovigerous golden king crabs Lithodes aequispinus. The host crab died subsequent to hatching of the fish eggs in one incident, but not in another. Because of gill damage caused by the egg mass, the fish-crab relationship is properly termed parasitism rather than commensalism.

Ovary of the golden crab, Chaceon fenneri: I. Post‐spawning and oosorption
Journal of Morphology, 1992AbstractOosorption has been considered an important strategy in many invertebrate species which occurs in response to behavioral, ecological, or physiological factors. In crustaceans, the early light microscopic studies of the ovary attributed a role in oosorption to follicle cells, hemocytes, or phagocytes.

Size-structured population dynamics models are used for stock assessments of hard to age invertebrate species, such as crabs, and size–transition matrices play an important role in modeling growth in those models. Crabs grow by molting and then incrementing in size.

The sperm of species of Geryon are typical of brachyurans in having a complex acrosome, a membranous lamellar complex, uncondensed chromatin in the nucleus, and nuclear arms or spikes of varying lengths. There are no microtubular elements in the arms. The spermatophores are ellipsoidal or round and contain varying numbers of sperm.
