Since the first molecular study of the suborder Notothenioidei in 1994, many phylogenetic studies have been published. Among these, those with a sufficient number of taxa have all suggested that the Nototheniidae, as currently defined, is monophyletic only with the inclusion of the Channichthyidae, Artedidraconidae, Bathydraconidae and Harpagiferidae. This is corroborated by more recent studies including more taxa, but in these studies either the number of nuclear markers or the number of taxa included remained low. We obtained sequences for a large sampling covering most nototheniid genera for five markers described previously for other samplings (COI, Rhodopsin retrogene, Pkd1, HECW2, and SSRP1) and one nuclear marker never used before in phylogenetic inference (PPM1d). The topology for the combined analysis of the nuclear coding genes, as well as the topology for SSRP1 (non-coding) and the combined analysis for all markers all support the paraphyly of Nototheniidae, the genus Notothenia (including Paranotothenia) is the sister group of the clade Channichthyidae, Artedidraconidae, Bathydraconidae and Harpagiferidae, and genus Gobionotothen is a sister group to both. As in previous studies, Trematomus, Lepidonotothen and Patagonotothen form a clade that also includes Indonotothenia cyanobrancha. The position of Pleuragramma antarctica, Dissostichus species and Aethotaxis mitopteryx remains unstable and dependant on markers and analyses. We therefore propose the inclusion of the four families of the High Antarctic clade in the Nototheniidae, and their transformation into subfamilies. We transfer Paranotothenia magellanica to the genus Notothenia, as Notothenia magellanica.
自1994年首次对南极鱼亚目进行分子研究以来，已发表了许多系统发育研究。其中，那些包含足够数量分类单元的研究均表明，当前定义的南极鱼科仅在纳入鳄冰鱼科、阿氏龙鰧科、深龙鰧科和裸吻鱼科时才是单系的。包括更多分类单元的最新研究证实了这一点，但在这些研究中，核标记的数量或所包含的分类单元数量仍然较少。我们获得了涵盖大多数南极鱼科属的大量样本的序列，这些样本来自之前其他样本研究中描述的五个标记（细胞色素氧化酶亚基I、视紫红质反转录基因、多囊蛋白1、造血相关E3泛素蛋白连接酶2和结构维持染色体相关蛋白1）以及一个从未用于系统发育推断的核标记（PPM1d）。核编码基因的联合分析拓扑结构，以及SSRP1（非编码）的拓扑结构和所有标记的联合分析均支持南极鱼科的并系性，南极鱼属（包括副南极鱼属）是鳄冰鱼科、阿氏龙鰧科、深龙鰧科和裸吻鱼科进化枝的姐妹群，而裸头南极鱼属是两者的姐妹群。与之前研究一样，红点鱼属、鳞头南极鱼属和巴塔哥尼亚南极鱼属形成一个进化枝，其中还包括蓝鳃印度南极鱼。南极冰鱼、南极犬牙鱼属物种和小眼斧鱼的位置仍然不稳定，并且取决于标记和分析。因此，我们建议将高南极进化枝的四个科纳入南极鱼科，并将它们转变为亚科。我们将麦哲伦副南极鱼转移到南极鱼属，即麦哲伦南极鱼。
