Fish, Benthic and Urchin Survey Data from Kahekili Herbivore Fisheries Management Area (HFMA), Maui, HI since 2008 (NCEI Accession 0165015)

browse graphicPreview graphic
Data are summary fish, benthic and urchin data from belt transect surveys conducted by the NOAA Coral Reef Ecosystem Program within the Kahekili Herbivore Fisheries Management Area (KHFMA) in West Maui. All transects are included.

Surveys were completed in 'rounds', each round being an intensive 4 day survey effort (occasionally with an additional day soon after) from 2009 to 2016. Also included are data gathered by Hawaii Division of Aquatic Resources in 2008 at the same locations and using the same survey design and methods.

Each row represents a single survey of a 25-m haphazardly located transect KHFMA. Habitat types are SAG (shallow agregate reef); DAG (Deep aggregate reef); MMX (Mixed mid-depth reef); SSG (shallow spur and groove); DSG (deep spur and groove); and SPA (shallow pavement).

Benthic cover (%) is extracted from a photo-transect (25 photographs, taken at 1 m intervals, 15+ points analyzed per photograph using Photogrid Image Analysis Software). NA values represent situations where images were either not gathered or not analyzed.

Fishes are surveyed by means of a diver swimming outward and return swims down the transects. On the outward swims, the diver records all fishes >15 cm total length (TL) within a 4-m wide belt centered on the diver; on the return swim, divers record fishes <15 cm TL within a 2-m wide belt. Fish species and size observations are converted to biomass (grams per square meter, or g/m^2) using species-specific length-weight conversion parameters. Urchins are counted on a 1-m wide belt centered on the transect line. Urchin density is calculated by the number per square meter (#/m^2).

Processing Steps
  • Data Type: REEF AND/OR BOTTOM REGIME - PERCENT COVER (measured); Units: percent; Observation Type: other; Sampling Instrument: camera; Sampling and Analyzing Method: The other survey diver followed the fish survey diver, and conducted a photo quadrat survey of the benthos under the transect line. Photos were later analyzed using point count image analysis software, with cover recorded to lowest possible taxonomic level (species for coral, genera for macroalgae, functional group for others [crustose coralline algae, turf, sand, other sessile invert]).; Data Quality Information: Benthic cover estimates derived from analysis of photographs are dependent on image quality - although that was generally good, as photographs were taken at less than 1 m from the reef substrate and in generally clear water, using a high resolution (8 MB) digital camera. Image quality is nearly always more than sufficient for there to be high confidence in accuracy of identification of benthic genera and functional groups.
  • Data Type: FISH BIOMASS (calculated); Units: grams/meter^2; Observation Type: in situ; Sampling Instrument: swimmer/diver; Sampling and Analyzing Method: Belt transect fish surveys are investigations that provide a high degree of taxonomic resolution for reef fish communities. The surveys were conducted by teams of two divers with locations haphazardly spread throughout the survey area. Transect placement was guided by: (1) a focus on hardbottom communities; (2) deploying lines along an isobath and parallel to shore. For each survey round, approximately 80-100 survey transects are conducted within the KHFMA. Survey teams comprising of divers and working off a small boat were haphazardly dropped over hardbottom areas throughout the KHFMA. The divers would then swim straight down to the nearest suitable habitat (hardbottom large enough to lay a survey transect in); one of the survey divers would then tie off the starting point of the survey transect and the other recorded the transect start location using a GPS in a waterproof bag attached to a float. As much as possible, surveys were always run parallel to the shoreline running approximately northwards. Survey transects were of 25m length.One of the divers conducted fish surveys, recording the species, number and size (in 5 cm slots) of all fishes recorded within the transect ahead of the diver as they swam slowly along the transect line. Fishes larger than 15 cm total length (TL) were recorded within a 4-m wide belt centered on the diver as they laid out the 25 m transect tape. At the end of the transect, the diver would then turn around and resurvey the transect line, recording species, number and size of all fishes smaller than 15 cm TL in a 2-m wide belt centered on the transect line.; Data Quality Information: The survey sites were selected using a haphazard process based on available habitat and bathymetric habitats and are believed to be highly representative. The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists. Fish observations were made by divers who have been trained, and met minimum standards in identifying species present at the survey locations and in estimating size of fishes in survey counts. However, all species identifications are made visually, sometimes in situations where a fish is only briefly seen. Observations, including species identification and sizing, were periodically checked during the expedition for consistency between divers, and little discrepancy was noted between divers. Data is checked after each survey trip, but there remains some possibility of typographical or other errors. Size estimates are checked against known size ranges per species.
  • Data Type: Density (calculated); Units: Number/meter^2; Observation Type: in situ; Sampling Instrument: swimmer/diver; Sampling and Analyzing Method: The other survey diver followed the fish survey diver, and after the photo quadrat survey was conducted, the diver then recorded all sea urchins within a 1-m wide belt, during a return swim down the transect line.
