Reef fish species, count, and abundance data collected during Hawaii Division of Aquatic Resources fish and habitat utilization surveys in East Hawaii from 2022-12-15 to 2023-10-20 (NCEI Accession 0287383)
Dataset contains reef fish species, count, and abundance data from sites located throughout the Eastern coastline of Hawaii Island. Fish data are derived from fish and habitat utilization surveys (FAHU) conducted by Hawaii Division of Aquatic Resources divers. FAHU surveys were conducted between December 2022 to October 2023. Fishes were visually identified to a species level when possible, and were then counted and sized (fork length in centimeters). A GPS attached to the dive float was used to determine the location of each transect. Coordinates continuously logged by the GPS correspond to the start and end times of each survey. The FAHU method uses stratified random sampling, where transects are randomly placed within four types of hard-bottom benthic habitats found in East Hawaii. Each FAHU transect consists of a paired fish and benthic survey, where one diver is responsible for the fish survey while the other diver conducts the benthic survey. The fish surveyor lays out the 25m long transect while recording all fish species observed within 2.5m swath on both sides of the transect line. This results in a 5m wide x 25m long surveyed area. The fish surveyor spends between 10-15 minutes counting fish to allow for fast moving and cryptic species to be recorded in the survey.

Fish and macroinvertebrate survey data collected from coral reef monitoring sites in West Hawaii from 2022-04-06 to 2022-11-18 (NCEI Accession 0288838)

The State of Hawaii DLNR (Department of Land and Natural Resources) DAR (Division of Aquatic Resources) marine monitoring team conducted surveys for fish and large mobile invertebrates along the West Hawaii coastline. Data were recorded along 5x25 meter transects at random sites going as far south as Manuka and as far North as Upolu Point. Data collection for one transect was completed at each site. Data are provided as individual observations noting species, quantity, and size of fish and species and quantity of invertebrates.
West Hawaii Aquarium Project (WHAP): fish and substrate data, 1999-2002 (NCEI Accession 0000938)

In response to declines in reef fishes, the Hawaii state legislature created the West Hawaii Regional Fishery Management Area in 1998 to improve fishery resources (Act 306). The West Hawaii Aquarium Project (WHAP) was funded by the Hawaii Coral Reef Initiative to monitor to fish populations and quantify the habitats in this region. This dataset consists of an MS Access relational database of all monitoring data from 1999-2002 and image and random point files of benthic habitat survey frames grabbed from video transects. During initial funding under CRAMP in 1998-99, 23 permanent study sites were established positioned in all of the proposed Fish Replenishment Areas (FRAs) as well as eight sites where fish collecting is know to occur ("impact"), and six managed areas where aquarium fish collection is prohibited (three Marine Life Conservation Districts (MLCDs) and three FMAs or "control"). Initial surveys confirm that aquarium fish collecting impacts are significant but vary along the coastline.
