The gill surfaces are covered in chitinous cuticle, which is permeable to gases, allowing gas exchange. Through rapid population growth, food access was limited for the king crab as well as for other benthic organisms including fish fry. In the Norwegian Sea, some evidence indicates that the red king crabs eat the egg masses of the capelin, which is an important prey for the cod. Fishing Seasons Table [edit | edit source] This table shows which months of the year the different types of fish will be of the best quality. Not only the king crab has made the Barents Sea new home ground. [6], Red king crabs are experiencing a steady decline in numbers in their native far east coastal waters for unclear reasons, though several theories for the precipitous drop in the crab population have been proposed, including overfishing, warmer waters, and increased fish predation. Red king crabs can grow as large as 28 cm (11 inches - carapace) with a leg span of up 1.8 m (5.9 ft). Scores range from zero to five where zero indicates very poor performance and five indicates the fishing operations have no significant impact. [7] Fishing controls set by the United States in the 1980s and 2000s have failed to stem the decline.[8].

[19], Overall, red king crabs have a high adaptation capacity in changes of salinity level because the crabs retain their vital functions and their feeding activities. Studies in the invasive species economic literature have typically sought to identify optimal management strategies in terms of control and prevention… A fisherman in Honningsvåg (a town near the North Cape) complained that the king crabs claw ruined fishing nets and deep lines.[16]. Juveniles are slightly more tolerant to low salinity because their volume regulation is significantly better. [2] Red king crabs can reach a carapace width up to 28 cm (11 in), a leg span of 1.8 m (5.9 ft),[3] and a weight of 12.7 kg (28 lb). Mönchengladbach, 13.

Results of investigations carried out in the Barents Sea show that the acclimatisation of the Red king crab follows the classic steps for the introduction of new species (intended or unintended introduction). [23]:622 To induce a current into the branchial chamber the crab uses back and forth movements of an appendage called the scaphognathite. They migrate in the winter or early spring to shallower depths for mating, but most of their lives are spent in the deep waters where they feed. Red king crabs exhibit unidirectional ventilation. In Zelenetskaya Bay (Dal’niye Zelentsy settlement area), for example, a decrease in sea-urchin biomass by a factor of 5 compared to the period before the Red king crab introduction has been recorded. Internal gills, like other specialized gills, need metabolic energy to pull water over the respiratory surface. [17], Mature female red king crabs must stay in warmer water (near 4 °C) to ensure the eggs will be ready for hatching, while the male red king crabs stay in relatively cold water (near 1.5 °C) to conserve energy. From the 1970s to the mid-1990s the acclimatisation process underwent the two first stages: survival of the resettled specimens (phase one), and reproduction and growth of the population (phase two).
