This information sheds light on larval distribution and spawning for fisheries management needs. This dataset includes larval fish abundances collected from 12 voyages around Australia since 1983, as well as more recent data from the Marine National Facility (MNF). The backbone of the dataset is from five Integrated Marine Observing Systems (IMOS) National Reference Stations (NRS) (North Stradbroke, Port Hacking, Maria Island, Kangaroo Island and Rottnest Island), between 2014 and 2021 as part of the IMOS Larval Fish Monitoring Sub-Facility of the National Mooring Network Facility (data currently available up to 2019). This adds information to the biological, ecological and oceanic measurements already sampled at these long-term monitoring sites. For information on using the data from the NRS stations and research voyages, please refer to Smith et al., 2018. It is advised that anyone using this data should read this methodology or contact the project contact person to understand the nuances of each sampling and analysis chain. The fish larvae product is available as raw count product, where fish larvae are classified to the lowest taxonomic level possible (with 228 taxonomic groups identified so far, at either the Family, Genus, or Species level). Associated metadata includes location, temperature, salinity, net type, and tow volume. There is a static snapshot of the database as at March 2018 (https://dx.doi.org/10.4225/69/5ab33c62f9c52), and this has been documented in a Scientific Data publication (Smith et al., 2018). This metadata record provides access to the dynamic (most recent) version of the database, which can serve as a data repository for survey of larval fish assemblages in the region.Ichthyoplankton samples are collected off small vessels at the IMOS National Reference Stations. Tows are generally 12 minutes in length, taken at depths of ~25m (although depth may vary between samples). The sampling methods are fully described in the IMOS NRS Biogeochemical Operations Manual (Davies & Sommerville, 2017). The analysis and quality control (QC) procedures, performed at the Sydney Institute of Marine Science (SIMS) and the Australian Museum Research Institute (AMRI), are described in Smith et al., 2018. Data sampling is being conducted as part of a larger IMOS monitoring program. All larval fish are extracted from ichthyoplankton samples under a microscope at SIMS and then transported to the Australian Museum. The sampling methods employed for voyage-derived larval fish data varies widely, with a variety of nets and mesh sizes used (see Hinchliffe et al., 2021 for a summary). Each MNF voyage has a unique number (beginning with FR, SS or IN), and each voyage summary can be found on the MARLIN data trawler. Larval fish are identified to the lowest taxonomic level possible by Tony Miskiewicz, who is a taxonomic expert in larval fish identification, using the Neira et al. (1998) guide to larval fish The abundance of each taxa found in the ichthyoplankton samples, alongside associated tow metadata, are then exported to IMOS. All larval fish from the IMOS National Reference Stations are archived in the Australian Museum's collection.
