This dataset contains the ichthyoplankton data from three National Reference Stations on the east coast of Australia (North Stradbroke Island, Port Hacking, and Maria Island), and comparable historical data from eight ichthyoplankton surveys that were used to provide a longer term context: RV Sprightly (1983) RV Challenger (1989-1991) RV Franklin (1994) RV Franklin (1997-1998) RV Franklin (1998-1999) RV Southern Surveyor (2004) RV Investigator (2015) FRV Kapala (1989-1993) Refer to the published report which had the following goals: - To evaluate the value of long-term monitoring of ichthyoplankton at selected locations in the Integrated Marine Observing System (IMOS) National Reference Station (NRS) network, - To identify the potential of this monitoring for providing fishery-independent information relevant for marine fishes and their management. Note - Currently only the data from the IMOS NRS Stations have been made available.
