- Abstract:
-
To support a long-term NOAA Coral Reef Conservation Program
(CRCP) for sustainable management and conservation of coral reef
ecosystems, from 2010-02-17 to 2010-03-23, reef fish assessment
surveys were conducted, as a part of Rapid Ecological
Assessments (REA), during the Pacific Reef Assessment and
Monitoring Program (RAMP) Cruise HA1001 in the American Samoa
region by the Coral Reef Ecosystem Division (CRED) at the NOAA
Pacific Islands Fisheries Science Center (PIFSC). During the
cruise, 24 REA sites were surveyed at Tau in the American Samoa
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.

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.
- Logical_Consistency_Report:
-
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.
- Completeness_Report:
-
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.

- Process_Description:
-
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.
