FBSAD Reef Fish-Habitat Quadrat Surveys at Hawaii Island (Big Island), Main Hawaiian Islands, 2005 (NODC Accession 0046935)
Habitat quadrats were surveyed at 8-13 m depths using shore-based transects swum at 3 longshore sites on the leeward coast (North and South Kohala districts) of the Big Island (Hawaii Island, in the MHI) during spring 2005. Substratum percent cover and rugosity were characterized within multiple quadrats at each site. A total 90 "Reference" ('REF') quadrats (whose positions were randomly selected) and a total 89 "Target" ('TAR') quadrats (positions centered on sightings of recruit fishes), each of 1-m2** area, were surveyed at the 3 Sites. In each quadrat, the percentage cover of each of seven (7) major substratum types were estimated, as was a "Rugosity Index". The study was published in a peer-reviewed marine science journal in August 2007.

FBSAD Reef Fish-HABITAT Quadrat Surveys at Hawaii Island (Big Island, Main Hawaiian Islands), 2008; and Midway Atoll (Northwestern Hawaiian Islands), 2008 (NODC Accession 0067519)
공공데이터포털
Habitat quadrats were surveyed at 1 to ~5 m depths using transects conducted at a total four (4) sites: (1-2) at 2 longshore sites on the leeward coast (South Kohala district) of the Big Island (Hawaii Island, in the MHI) during spring-summer 2008; and (3-4) at 2 longshore sites on the back reef of Midway Atoll (NWHI) in summer 2008. Substratum cover and rugosity were characterized within multiple quadrats at each site. Two types of quadrats were surveyed: "Reference" ('REF') quadrats (whose positions were randomly selected) and "Target" ('TAR') quadrats (positions centered on sightings of recruit fishes); each quadrat was square and 1-m**2 area. In each quadrat, the benthic cover of each of fourteen (14) main substratum types were estimated, as was a "Rugosity Index" based on the ratio of conforming-to-straight line distances along both major axes of the quadrat.

CRED Rapid Ecological Assessment Reef Fish Survey at Hawaii, Main Hawaiian Islands in 2010
공공데이터포털
To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 20101007 to 20101105, reef fish assessment surveys were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) Cruise HA1008 in the Main Hawaiian Islands region by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, 43 REA sites were surveyed at Hawaii in the Main Hawaiian Islands region. At each REA site, fish biologists entered the water and conducted a fine-scale (~700 m^2) and high degree of taxonomic resolution REA survey to assess and monitor species diversity, size distribution, and abundance of fish in shallow-water hard-bottom (less than 30 m) habitats. Reef fish assessment surveys were focused on cataloging the diversity (species richness), abundance (numeric density) and biomass (fish mass per unit area) of diurnally active reef fish assemblages. The stationary point count (SPC) method was used to quantify reef fish species. Two divers lay out a 30 m transect line, and position themselves at the 7.5 and 22.5 meter marks. The SPC biologist then records estimated size and abundance of all fish within a visually estimated 15-m diameter cylinder centered on the stationary diver (7.5-m radius, total area ~ 177m^2 per cylinder). The diver first spends 5 minutes identifying all fish species in the cylindrical area, then proceeds to count and estimate size (total length) for each in a series of "instantaneous" point counts or sweeps of the cylinder. Fish were identified at the species level, wherever possible. All reef-associated fish, including those in the water column, were surveyed. The survey time for each stationary point count survey was approximately 20 min and generally four stationary point count surveys (two per diver) were conducted at each fish REA site. After completing REA surveys, divers noted the presence, at the survey site, of any unusual fish species not counted during SPC counts, in order to facilitate species lists per location.

West Hawaii Aquarium Project 1999-2003 Fish and Substrate Data (NODC Accession 0001467)
공공데이터포털
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 1999-2003. The relational database of this dataset includes some of the data held in NODC Accession 0000938, however, it would be best to examine each accession carefully. The relational database of this accession has fewer tables and less parameters. 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.

FBSAD PREDATOR Reef Fish Belt Transect Survey at Hawaii Island (Big Island), Main Hawaiian Islands, 2006 and 2007; Oahu (Kaneohe Bay), Main Hawaiian Islands, 2007 only; and Midway Atoll, Northwestern Hawaiian Islands (NWHI), 2006 and 2007 (NODC Accession 0056602)
공공데이터포털
Shore-based belt transects were conducted at 1 to ~5 m depths at a total seven (7) sites: at (1-2) 2 longshore sites on the leeward coast (South Kohala district) of the Big Island (Hawaii Island) in the MHI during spring 2006 and 2007; (3) at 1 site-group comprising multiple patch reefs located throughout north, central and south Kaneohe Bay, windward Oahu in the MHI during spring 2007; (4-5) at 2 longshore sites on the back reef of Midway Atoll in the NWHI during spring 2006 and spring-summer 2007; and (6-7) at 2 site-groups comprising multiple patch reefs within the Welles Harbor region of the lagoon of Midway Atoll during spring-summer 2007. From 12-20 randomly positioned transects were surveyed at each site or site-group in a given year; each transect was 50-m long x 4-m wide (200 m**2 area). Raw survey data consist of species-specific and size-specific (total length, TL, in cm) numerical counts of large juvenile and adult (= 6 cm total length, TL) stages of PREDATOR reef fishes encountered within transect boundaries. Inclusion as a predator fish in the transect tally was based on either known or likely (based on functional morphology) inclusion of small fishes in the species' diet.
