| 英文摘要: | The king crab move further out in the sea in Russian waters compared to
the Norwegian waters. This might have important implications on the distribution of
feeding pressure and impact of crabs on benthic communities making them different in
different areas. Though the king crab population is still spreading along the coast, the
snow-crab population, spreading on the seafloor of the open sea, is expected to increase
beyond the standing stock of king crab. The king crab has a measurable effect from
foraging on large visible sea stars, brittle stars and bivalves and preferable prey will
decrease while species, not preferred, will become dominant together with “hide or
flight” bottom animals. Some areas show sign of almost extinction of large prey, and
borrowing fauna inside the sediment might have decreased due to the foraging from the
crab, and consequently left the sediment environment low in oxygen. Areas with refuge
still have high biodiversity. |
