本文采用分生和遗传方法对新西兰专属经济区内的黑异卵母细胞瘤（尼日尔，James，Inada &中村，1988）和斑拟卵母细胞瘤（Pseudocyttusmaculatus，Gilchrist，1906）的种群关系进行了研究。在1998年10月至12月产卵期间，从四个管理区-OEO 1（西南）、OEO 3A（查塔姆隆起西部）、OEO 4（查塔姆隆起东部）和OEO 6（亚南极）采集样本。侧线鳞片计数和幽门盲囊计数显示，OEO 6和其他三个OEO管理区的黑奥雷样品之间的差异。在光滑的奥雷奥侧线鳞片计数没有显着差异的地区。对黑奥雷奥核DNA和线粒体（mt）DNA单倍型的四个非编码区的遗传分析显示，四个管理区之间没有显着差异。同样，对于光滑的oreo，对核DNA和mtDNA单倍型的五个非编码区的遗传分析显示没有总体的区域差异，尽管在一个位点上存在OEO 3A和OEO 6之间差异的微弱证据。这些数据不拒绝零假设的一个单一的遗传股票在新西兰沃茨，是典型的海洋物种与长的远洋少年阶段。
Abstract Meristic and genetic methods were used to determine the stock relationships of black Allocytus niger (James, Inada & Nakamura, 1988) and smooth oreo Pseudocyttus maculatus (Gilchrist, 1906) in the New Zealand Exclusive Economic Zone (EEZ). Samples were collected from four management areas—OEO 1 (south‐west), OEO 3A (Chatham Rise west), OEO 4 (Chatham Rise east), and OEO 6 (subantarctic) during the 1998 October‐December spawning period. Lateral line scale counts and pyloric caeca counts revealed differences between black oreo samples from OEO 6 and the other three OEO management areas. Lateral line scale counts in smooth oreo showed no significant differences between areas. Genetic analyses of four non‐coding regions of nuclear DNA and mitochondrial (mt) DNA haplotypes in black oreo showed no significant differentiation among the four management areas. Likewise for smooth oreo, genetic analyses of five non‐coding regions of nuclear DNA and mtDNA haplotypes showed no overall regional differentiation, although there was weak evidence at one locus for a difference between OEO 3A and OEO 6. The data do not reject the null hypothesis of a single genetic stock in New Zealand waters, and are typical of marine species with long pelagic juvenile stages.
