Knowing the distribution of fish larvae can inform fisheries science and resource management in several ways, by: 1) providing information on spawning areas; 2) identifying key areas to manage and conserve; and 3) helping to understand how fish populations are affected by anthropogenic pressures, such as overfishing and climate change. With the expansion of industrial fishing activity after 1945, there was increased sampling of fish larvae to help better understand variation in fish stocks. However, large-scale larval records are rare and often unavailable. Here we digitize data from Nishikawa et al. (1985), which were collected from 1956-1981 and are near-global (50°N-50°S), seasonal distribution maps of fish larvae of 18 mainly commercial pelagic taxa of the families Scombridae, Xiphiidae, Istiophoridae, Scombrolabracidae, and Scomberesocidae. Data were collected from the Pacific, Atlantic, and Indian Oceans. We present four seasonal 1° × 1° resolution maps per taxa representing larval abundance per grid cell and highlight some of the main patterns. Data are made available as delimited text, raster, and vector files.
1）提供产卵区域的信息；2）确定管理和保护的关键区域；3）帮助了解鱼类种群如何受到人为压力（如过度捕捞和气候变化）的影响。自 1945 年以来，工业捕鱼活动的扩张增加了对鱼类幼体的采样，以帮助更好地了解鱼类种群的变化。然而，大规模的幼体记录很少且往往不可用。在这里，我们对 Nishikawa 等人（1985 年）的数据进行了数字化，这些数据是在 1956 年至 1981 年间收集的，几乎涵盖了全球范围（50°N-50°S），包括 18 种主要商业性中上层鱼类的鱼类幼体的季节性分布图，这些鱼类属于鲭科、剑鱼科、箭鱼科、旗鱼科和鲭鱼科。数据来自太平洋、大西洋和印度洋。我们为每个类别呈现了四个季节性的 1°×1°分辨率地图，代表每个网格单元的幼体丰度，并突出了一些主要模式。数据以带分隔符的文本、栅格和矢量文件形式提供。
