The high level of taxonomic expertise required to identify larval fishes to species level, and the considerable effort required to collect them, make these data extremely valuable. Here we collate 3178 samples of larval fishes, from 12 research projects from 1983 to November 2016, from temperate and subtropical Australian waters. This forms a benchmark for the larval fish assemblage for the region, and includes recent monitoring of larval fishes at coastal oceanographic reference stations. Comparing larval fishes among projects can be problematic to due to differences in taxonomic resolution, and identifying all taxa to species can extremely challenging, so this study reports a standard taxonomic resolution (of 221 taxa) for this region to help guide future research. All data reported here has been expertly resolved to this taxonomic resolution. The ongoing version of this larval fish database will be freely available through the Australian Ocean Data Network Portal (AODN; http://portal.aodn.org.au/) in the near future, and will serve as a data repository for surveys of larval fish assemblages in the region.All larval fishes were sampled by plankton nets towed from a variety of vessels. Nets were either towed obliquely (across a range of depths), or at constant near-surface depths. Upon net retrieval of this single ‘tow’, all plankton were fixed immediately in ~4% formalin in seawater (and often buffered with sodium borate or sodium carbonate to avoid sample degradation). The volume sampled by the net for each tow was determined, typically using a flowmeter attached to the mouth of the net, which was used to standardise larval fish counts to volume of water sampled. See data paper for information on the larval fish identification.Project_ID; Project_name: Unique database code to identify the project (Table 1) Tow_ID: A unique identifier for each tow, which is the Project_ID plus the numerical data record for that project; e.g. P1_1 is the first record in project P1 Sample: A project-specific identifier for each record Date: Date a tow was taken, yyyy-mm-dd Time_local: The local time a tow was taken, hh24:mm Day_Night: Whether the tow occurred in the day or night – only used when Time_local was unavailable Latitude; Longitude: Geographic coordinates for each tow (usually start of tow) Location: A project-specific identifier of feature of interest (e.g. oceanographic feature) Volume_m3: The volume of a tow (m3) Replicate: Identifies when tows were done consecutively to act specifically as replicates Cruise_ID: A project-specific identifier of different cruises Station: A project-specific identifier of a specific location sampled multiple times Gear_depth_m: The maximum depth tows were deployed to, or a range of depths sampled; surface tows have a depth=0 Gear_mesh_um: The type of net, and the mesh dimensions (μm); summarised in Table 1 Bathym_m: The bottom depth at location of the tow (m) Temperature_C: Surface (< 10 m) water temperature (°C) at approx.. the same time as the tow; measured with a CTD Salinity: Surface (< 10 m) salinity (PSU) at approx. the same time as the tow; measured with a CTD&rft.creator=Smith, James A. &rft.creator=Miskiewicz, Anthony G. &rft.creator=Beckley, Lynnath E. &rft.creator=Everett, Jason D. &rft.creator=Garcia, Valquiria &rft.creator=Gray, Charles A. &rft.creator=Holliday, David &rft.creator=Jordan, Alan R. &rft.creator=Keane, John &rft.creator=Lara-Lopez, Ana &rft.creator=Leis, Jeffrey M. &rft.creator=Matis, Paloma A. &rft.creator=Muhling, Barbara A. &rft.creator=Neira, Francisco J. &rft.creator=Richardson, Anthony J. &rft.creator=Smith, Kimberley A. &rft.creator=Swadling, Kerrie &rft.creator=Syahailatua, Augy &rft.creator=Taylor, Matthew D. &rft.creator=van Ruth, Paul D. &rft.creator=Ward, Tim M. &rft.creator=Suthers, Ian M. &rft.date=2018&rft.coverage=northlimit=-20.00; southlimit=-44.00; westlimit=110.00; eastLimit=160.00&rft.coverage=northlimit=-20.00; southlimit=-44.00; westlimit=110.00; eastLimit=160.00&rft_rights=Creative Commons Attribution 4.0 International License http://creativecommons.org/licenses/by/4.0&rft_subject=biota&rft_subject=oceans&rft_subject=Ship: Southern Surveyor&rft_subject=Ship: Franklin&rft_subject=Ship: Sprightly&rft_subject=Ship: Investigator (RV)&rft_subject=Ship: Kapala&rft_subject=Ship: Challenger&rft_subject=PLANKTON&rft_subject=EARTH SCIENCE&rft_subject=BIOSPHERE&rft_subject=AQUATIC ECOSYSTEMS&rft_subject=FISH&rft_subject=BIOLOGICAL CLASSIFICATION&rft_subject=ANIMALS/VERTEBRATES&rft_subject=Research Voyage: FR 02/97&rft_subject=Research Voyage: FR 14/98&rft_subject=Research Voyage: IN2015_V03&rft_subject=Research Voyage: FR 01/99&rft_subject=Research Voyage: FR 04/94&rft_subject=Research Voyage: FR 11/97&rft_subject=Research Voyage: FR 02/94&rft_subject=Research Voyage: SS 08/2004&rft_subject=Temperature of the water body&rft_subject=Practical salinity of the water body&rft_subject=Biotic taxonomic identification&rft_subject=plankton nets&rft.type=dataset&rft.language=English Access the data
