海洋省，建立在对比的植物群或动物群，已被承认超过150年，但并没有一致的特有性定义，直到1974年。当时，各省至少有10%的特有性，并嵌套在地理区域内，覆盖了大面积的地理区域，具有对比鲜明的生物特征。随着时间的推移，进行了一些小的调整，但总体安排基本上保持不变。在许多省份，仍然没有关于特有现象的数据，或只有关于最广泛研究的脊椎动物（鱼类）的数据，这是一个持续存在的问题。在本报告中，我们提出重新调整有三个原因。首先，最近的工作提供了新的信息，以修改或重新定义各种分区，并描述新的分区，包括大西洋中脊，南大洋，热带东太平洋和东北太平洋。第二，地理学研究表明，物种内部和物种之间的遗传细分，一般证实了基于分类分区的省份，在印度-太平洋海洋边界有一个显着的例外。第三，暖温带省份与邻近的热带省份最初的分离分散了它们之间密切的系统发育关系。在这里，我们建议将暖温带和热带地区合并为每个海洋盆地内的一个单一的温暖地区，同时仍然承认暖温带和热带地区内的省份。这些鱼类地理细分主要基于鱼类分布，但利用其他海洋群体进行比较。其目的是展示海洋生物群的进化关系，并作为在养护方面建立较小生态单位的框架。
Marine provinces, founded on contrasting floras or faunas, have been recognized for more than 150 years but were not consistently defined by endemism until 1974. At that time, provinces were based on at least a 10% endemism and nested within biogeographic regions that covered large geographic areas with contrasting biotic characteristics. Over time, some minor adjustments were made but the overall arrangement remained essentially unaltered. In many provinces, data on endemism were still not available, or were available only for the most widely studied vertebrates (fishes), a problem that is ongoing. In this report we propose a realignment for three reasons. First, recent works have provided new information to modify or redefine the various divisions and to describe new ones, including the Mid-Atlantic Ridge, Southern Ocean, Tropical East Pacific and Northeast Pacific. Second, phylogeographic studies have demonstrated genetic subdivisions within and between species that generally corroborated provinces based on taxonomic partitions, with a notable exception at the IndianPacific oceanic boundary. Third, the original separation of the warm-temperate provinces from the adjoining tropical ones has distracted from their close phylogenetic relationships. Here we propose uniting warm-temperate and tropical regions into a single warm region within each ocean basin, while still recognizing provinces within the warm-temperate and tropical zones. These biogeographic subdivisions are based primarily on fish distribution but utilize other marine groups for comparison. They are intended to demonstrate the evolutionary relationships of the living marine biota, and to serve as a framework for the establishment of smaller ecological units in a conservation context.
