Locality records are given of the capture of a number of king crabs in British Columbia waters. The extension of the known range of Lithodes aequispina to southern British Columbia is also reported. As these two species can be easily confused, figures and anatomical comparisons are provided.

Paralithodes Camtschatica

Fish eggs containing Careproctus embryos were found in the gill cavity of Lopholithodes foraminatus caught off British Columbia. Because the gills were collapsed and displaced, thus implying impaired respiration for the crab, we consider this fish–crab association to be commensal rather than symbiotic. The embryos are probably those of C. melanurus. Because of previous reports of other Careproctus sp. depositing eggs in king crabs (Paralithodes camtschatica), further investigations to indicate the host specificity of this liparid–lithodid relationship are needed.

Paralithodes Camtschatica

Egg masses of 772 red king crab, Paralithodes camtschatica, were sampled to determine the prevalence, intensity, and patterns of cooccurrence of brood symbionts from 28 Alaskan localities. Carcinonemertes regicides and three other undescribed nemertean egg predators were recovered from many localities, as were an undescribed turbellarian and an amphipod, Ischyrocerus sp. A widespread outbreak of nemerteans occurred in the 1983–84 and 1984–85 red king crab brooding seasons. At some locations, nearly all of the eggs were consumed in the 1983–84 brood season. Feeding of C. regicides on eggs was documented in vitro and these worms caused substantial egg mortality at many locations. The amphipod was also an egg predator and may have had a significant impact at three locations. The turbellarian did not kill eggs. From the seasonal pattern of C. regicides infestation at Kachemak Bay, we postulate an abbreviated life cycle and autoinfection for C. regicides. Such life history features may have contributed to the peak intensities observed late in the 1983–84 and 1984–85 brooding seasons. At some localities, heavy brood mortality may reduce or eliminate recruitment of some year classes to the fishery.
