摘要

俄罗斯于2010年在大西洋南部开始了对南极蟹捕捞可能性的研究(Anosov, 2012)。随后出现了研究在南极洲太平洋地区捕捞螃蟹的可能性的想法,此前没有人进行过此类研究,但已知有潜在商业品种的螃蟹被捕获到延绳钓(Anosov, 2015)。实现是在2018/2019赛季,当研究计划的第一阶段完成。目的是确定88.2区和88.3区螃蟹的种类组成,初步确定螃蟹的分布。螃蟹的捕捞是在锥形的锅里进行的,这些锅被按顺序分成120块。平均停滞时间为32小时42分钟。发生蟹类3种。只有一种可以被认为是潜在的商业物种-新石竹。通过这些研究,首次获得了南极石蟹科蟹类的种类组成、形态参数、水深和空间分布等资料。

The brief results of the research of antarctic crabs in the Pacific sector of Antarctic
Russian research into the possibility for fishing of Antarctic crabs was started in 2010 in the South part of Atlantic Ocean (Anosov, 2012). Subsequently appeared the idea to study the possibility of crab fishing in the Pacific sector of Antarctica, where no one had previously conducted such studies, but it was known about by-catch of potentially commercial species of crabs to the longline (Anosov, 2015). The realization is came in the season of 2018/2019, when the first stage of the research program was completed. The purpose was to establish the species composition and the primary determination of the distribution of crabs in the area 88.2 and in the area 88.3. Crab fishing was carried out with the help of conical pots, which were set in 120 pieces in order. The average stagnation time was 32 hours 42 minutes. 3 species of crabs were occurred. Only one can be considered as potentially commercial species – Neolithodes yaldwini. As a result of these studies, data on the species composition, morphological parameters, bathymetric and spatial distribution of Antarctic species of crabs of the family Lithodidae were obtained for the first time.
