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 2022 The Author s
