Abstract

In order to ensure the fisheries development and conservation of biological resources in the northern sea of the Antarctic Peninsula, this study uses the scientific survey (EK60, Simrad; 38kHz,120 kHz) of R/V Xue Long in January 2016. The result shows: The total abundance of Euphausia superba Dana in the whole investigation area (51953.4 nmi2) was 3457.03 t (101129.74 ind/nmi2, 55410.77 g / nmi2). The total abundance of the Thysanoessa macrura G.O. Sars was 81.43 t (35098.15 ind/nmi2, 3215.01g/nmi2).
