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, 16 REA sites were surveyed at Lanai 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.
Part of a biennial long-term monitoring program which documents
status and trends of coral reef ecosystems within the United
States Pacific Territories.

Observations at each site 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 cruise, but given the size of the
data set, there remains some possibility of typographical or
other errors.
The same methods of data collection were used at each of the sites
surveyed at this location, and were conducted by the same scientists.
Periodic examination of the data through the duration of the trip
showed no clear indication of diver bias or other discrepancies.
The survey sites were randomly selected using a systematic process
based on available habitat and bathymetric habitats. However,
although efforts are made to include broad spatial coverage,
weather conditions and other environmental constraints may have
prevented the team from surveying exposed reef areas.

REA surveys are investigations that provide a high degree of
taxonomic resolution for reef fish communities. The surveys
were conducted by teams of two fish divers following a random
stratified design. Sites were randomly chosen within three
depth strata for hard-bottom or unknown reef areas. These
areas included forereef slopes of individual islands at depths
up to 30 meters, lagoonal-type patch reefs and offshore
oceanic banks. Transect placement was guided by: (1) a focus
on hard-bottom communities; (2) deploying lines along an
isobath to the extent possible at each site, and (3) laying
the transect lines into the prevailing current, if any.
