9714439 Gaffney Characterizing the population structure of important Antarctic species is essential to an improved understanding of Antarctic ecology, and the successful management of this ecosystem. The British Antarctic Survey (BAS) has initiated a collaborative international effort (Project Gene Flow) aimed at delineating population structure in several key species (fish, squid and krill). A one-month cruise in the Scotia Sea to obtain biological specimens and oceanographic data is scheduled for November 1977, and this represents a unique opportunity to apply both established and novel molecular techniques to an important problem in Antarctic resource management. Four commercially and/or ecologically important species will be the primary targets of the research: mackerel icefish, Patagonian Toothfish, Antarctic Krill and the Seven Star Flying Squid. A variety of molecular genetic techniques, including some that are well-established and others that are novel but extremely promising, will be applied to delineate genetic population structure in these species. This research will provide information on the whether separate "stocks" or genetically different populations of these species exist in Antarctic waters. This information will be useful in the management of these species.

9714439加夫尼描述重要的南极物种的种群结构对于更好地了解南极生态和成功管理这个生态系统至关重要。英国南极调查局（BAS）发起了一项国际合作努力（基因流项目），旨在描绘几个关键物种（鱼类、鱿鱼和磷虾）的种群结构。定于1977年11月在斯科舍海进行一次为期一个月的航行，以获取生物标本和海洋学数据，这是一个独特的机会，可以将现有的和新的分子技术应用于南极资源管理的一个重要问题。 研究的主要目标是四种具有商业和/或生态重要性的物种：鲭鱼冰鱼、巴塔哥尼亚齿鱼、南极磷虾和七星星星飞鱼。各种分子遗传学技术，包括一些已经建立的和其他的是新的，但非常有前途的，将被应用于描绘这些物种的遗传种群结构。这项研究将提供关于南极沃茨是否存在这些物种的单独“种群”或遗传上不同的种群的资料。这些信息将有助于这些物种的管理。
