    • Akule and 'Opelu Larval Data from Plankton Tows Conducted off the Kona Coast in West Hawai'i between 1997 and 2018

    Metadata Updated: October 19, 2024

    The data described here includes the analysis of plankton samples for the presence and size of akule and 'opelu larvae, as well as the tow metadata of samples including tow type, mesh size, and distance from shore. This data was collected as a part of Pacific Island Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD)'s West Hawai'i Ichthyoplankton Time Series Project. This project targeted the biosampling of commercially important species including billfish and tuna, but included all available ichthyoplankton; from 2016-2018 the focus shifted to plankton community structure around the island and in/out of oceanographic features. This data was produced by analysis of plankton samples collected off the Kona Coast of Hawai'i from 1997 throughout 2018 by NOAA ships and small boats. Ichthyoplankton samples were collected by 6 ft. Isaacs-Kidd Midwater Trawls and 1m ring-nets towing aside the ships/boats. Neuston and vertical tows were conducted from 2016-2018 to better assess the vertical distribution of larvae in the top 10m.

    Lineage The West Hawai'i Ichthyoplankton Time Series began in 1997, when ichthyoplankton was collected by neuston tows off West Hawai'i to assess the spatial and temporal variability in larval distribution and abundance. Samples were analyzed under microscope and larvae were identified, counted and measured for length. Distance from shore and mean bottom depth metrics were also utilized in the analysis of akule and opelu larval ecology. Environmental metadata helps us monitor seasonal occurrence, vertical distribution, habitat and temperature associations, and cross-shore distribution of larvae. The response of larvae to oceanographic conditions can provide insight into how the environment may modulate recruitment.
