Variability of krill, Euphausia superba, Dana 1852 (Crustacea, Euphauciacea), distribution and biomass in the western Antarctic (Bransfield Strait, Drake Passage, Elephant Island) during 1976-1987


, : Variability of krill, Euphausia superba, Dana 1852 (Crustacea, Euphauciacea), distribution and biomass in the western Antarctic (Bransfield Strait, Drake Passage, Elephant Island) during 1976-1987. Investigacion Pesquera (Barcelona): 524: 575-586

Data on the distribution and biomass of krill in the years 1976-1987 have been compiled. The fluctuations of the mean surface density are very large, from 0.26 t/Nm2 to 153 t/Nm2. Krill biomass increases from October to February, and then in March decreases. It is calculated that the increment due to the growth of animals is about six times, that due to inflow with currents about 10 times during Antarctic summer (from December to February). It is suggested that hydrodynamical and synoptical factors as well as bottom topography are mainly responsible for the krill distribution and biomass fluctuations.
