Effects of habitat complexity and relative larval supply on the establishment of early benthic phase red king crab (Paralithodes camtschaticus Tilesius, 1815) populations in Auke Bay, Alaska
Between September 1996 and May 1998, the influence of habitat complexity and larval supply on the establishment of early post-settlement populations of red king crab (Paralithodes camtschaticus) was studied in situ in Auke Bay, southeast Alaska. Dive transects and suction dredge surveys conducted during fall 1996 and spring 1998 indicated that late age 0 to 1 1 red king crabs were located only ...

An extensive area in Bristol Bay, Alaska, was proposed as a no-trawling zone to protect red king crab habitat from potential impacts. The Bristol Bay red king crab stock has remained at low abundance levels since a stock collapse in 1980. A literature review indicated that the proposed area encompassed all available habitat essential for red king crab juveniles of this stock. Published studies ...

متن کاملHabitat structure influences the survival and predator–prey interactions of early juvenile red king crab Paralithodes camtschaticus
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 lengt...
متن کاملEffects of Ocean Acidification on Juvenile Red King Crab (Paralithodes camtschaticus) and Tanner Crab (Chionoecetes bairdi) Growth, Condition, Calcification, and Survival
Ocean acidification, a decrease in the pH in marine waters associated with rising atmospheric CO2 levels, is a serious threat to marine ecosystems. In this paper, we determine the effects of long-term exposure to near-future levels of ocean acidification on the growth, condition, calcification, and survival of juvenile red king crabs, Paralithodes camtschaticus, and Tanner crabs, Chionoecetes b...
