Distribution of Euphausia crystallorophias within Prydz Bay and its importance to the inshore marine ecosystem

  • P. G. Thomas
  • K. Green


Within Prydz Bay (Antarctica) Euphausia crystallorophias was found to be restricted to the continental shelf (<1000 m). Densities greater than 1000 indiv. 1000 m-3 were observed nearer the coast, while lower densities were seen further offshore. E. crystallorophias was the dominant euphausiid in the shelf region with the occurrence of Euphausia superba increasing close to the continental shelf break and further off the shelf. E. crystallorophias was found to be an important component of the diet of Adelie penguins (Pygoscelis adeliae) breeding on Magnetic Island in Prydz Bay. The importance of E. crystallorophias as a dietary item for other predators in the region is discussed.
