“…Juvenile red king crabs have been observed stacked in large 3-dimensional pods during the day and then spreading out to forage at night as a mobile foraging group (Powell & Nickerson 1965, Dew 1990. Less is known about fine-scale adult behavior, because adults spend much of their lives at depths where direct observation is difficult.…”

“…While re ports exist of young-of-year red king crab being collected from depths >100 m (Powell and Nickerson 1965), this appears to be uncommon. Sampling of the southeastern Bering Sea has failed to demonstrate any settlement below 50 m, despite the existence of apparently suitable settlement habitat and the pres ence of competent larvae in the water column directly above (McMurray et al 1984).…”

“…The association of early juvenile red king crab with complex habitat was first documented in the field (e.g. Powell & Nickerson 1965, Sundberg & Clausen 1977 and only recently demonstrated by laboratory studies to be the result of active habitat selection (Stevens & Kittaka 1998, Stevens 2003, foraging opportunities (Pirtle & Stoner 2010), and predator avoidance (Stevens & Swiney 2005, Stoner 2009). …”

“…Habitat choice is also driven by foraging opportunities, par ticularly when biogenic habitats are present (Pirtle & Stoner 2010). After Age 2, juvenile crabs emerge from complex habitats to form 'pods', mobile aggregations of hundreds to thousands of individuals (Powell & Nickerson 1965, Dew 1990). Red king crab growth and maturity are temperature dependent, and red king crabs mature at ages ranging from 5 to 12 yr (Stevens 1990).…”

Highly structured nursery habitats promote the survival of juvenile stages of many species by providing foraging opportunities and refuge from predators. Through integrated laboratory and field experiments, we demonstrate that nursery habitat structure affects survival and predator-prey interactions of red king crab Paralithodes camtschaticus. Crabs (< 1 yr old [Age 0]; 8 to 10 mm carapace length [CL]) preferred complex biogenic habitats formed by structural invertebrates and macroalgae over structural mimics and sand in the absence of predators in laboratory experiments, yet they associated with any available structural habitat when fish predators were present. Survival was higher in the presence of complex habitat for Age 0 crabs (5 to 7.5 mm CL) with Pacific cod Gadus macrocephalus predators in the laboratory and for Age 0 (4 to 8 mm CL) and Age 1 (16 to 28 mm CL) crabs with fish and invertebrate predators in the field. Crab activity and refuge response behavior varied with crab stage and habitat. Age 0 crabs were cryptic, avoiding predators by associating with habitat structure or remaining motionless in the absence of structure, and were less likely to respond to an attack. In contrast, Age 1 crabs were more likely to respond to an attacking predator and were less likely to remain motionless in the absence of structural refuge, suggesting an ontogenetic shift in behavior. Complex habitats, cryptic behavior, and direct defense improve juvenile red king crab survival against certain predators, including demersal fishes.
