1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:
Guam Long-term Coral Reef Monitoring Program Reef Fish Surveys since 2010
1.2. Summary description of the data:

The Government of Guam's Long-term Coral Reef Monitoring Program (GLTMP), coordinated through the Guam Coastal Management Program until October 2013 and now coordinated through the University of Guam Marine Laboratory, involves the collection of data for a suite of coral reef ecosystem health parameters at several high priority reef sites around the island of Guam. The program currently utilizes a split-panel sampling approach, whereby a mix of permanent and non-permanent sampling stations (one sampling station = one transect) are visited within each site. The monitoring sites were selected by an advisory body comprised of reef managers, researchers, and technicians. The locations of the sampling stations within each site are generated randomly using GIS software. Various coral reef surveys are carried out on an annual basis along the seaward slope between 7 and 15 m depth in the Tumon Bay Marine Preserve and East Agana Bay sites. Surveys are carried out less regularly along the seaward slope between 7 and 15 m depth in the Piti Bomb Holes Marine Preserve, the Achang Reef Flat Marine Preserve, the eastern side of the Cocos Barrier Reef (Cocos-East), and along the seaward slope (5–8 m) in Fouha Bay. Surveys were also carried at along reef margin (1–2 m) and slope (2–15 m) of Western Shoals, in Apra Harbor, in 2011. The surveys, which are conducted by University of Guam Marine Lab and NOAA PIRO biologists currently include benthic photo transects, quadrat surveys for coral colony size and condition, stationary point count fish surveys, macroinvertebrate belt transects, and chain-length rugosity surveys. These surveys have been conducted at the Tumon and East Agana sites since 2010 and the Piti site since 2012. Data collection for the Achang and Cocos-East sites has occurred in 2014, 2018, and 2021, and at the Fouha Bay site in 2015, 2019, and 2021. Baseline data is available for the Western Shoals site from 2011 but this site has not been re-visited since its establishment due to shifting management priorities.

Fish are a culturally and economically valuable resource for the island of Guam (van Buekering et al., 2007). In recognition of the high value of this resource, reef fish surveys are a key component of the Guam Long-term Coral Reef Monitoring Program. Reef fish assessment surveys have been conducted at high priority reef sites around Guam since August 2010. The monitoring team uses a Stationary Point Count Method, adapted from Ault et al. (2006) and NOAA Fisheries, Coral Reef Ecosystem Division (Williams et al., 2011), to conduct the reef fish surveys. These monitoring data on reef fish communities provide results on fish density, biomass, and diversity; allow for exploration of community structure by functional group and size structure; and can be used to detect changes in fish communities over time.

IMPORTANT NOTE: Changes have been made to the fish SPC survey methodology since its first deployment in 2010. These changes, which are documented in the Data Quality and Lineage sections of this metadata record, must be considered in order to properly analyze these data. Also, please note that the results of a 2020 analysis of the fish SPC data conducted by Dr. Peter Houk of the University of Guam Marine Laboratory indicated that data collected in 2010 and 2011 by one observer, and data collected by another observer at single site in 2015, did not meet quality assurance standards. In response to the results of this analysis observations recorded by these two observers are not included in the dataset submitted to NCEI. However, these data can be made available upon request. More information regarding Dr. Houk's analysis can be found in the Data Quality section of the metadata record.

(describe or provide URL of description):

Lineage Statement:
The Stationary Point Count Survey methodology for reef fishes, employed by the Guam Long-term Coral Reef Monitoring Program since 2010.

Process Steps:

  • The fish team uses a Stationary Point Count Method (SPC) adapted from Ault et al. (2006) and NOAA Fisheries Coral Reef Ecosystem Division (Williams et al., 2011). Slight modifications to the method were made in 2012, allowing more refined classification of non-instantaneous observations, but more substantial changes to the method were implemented beginning in 2020. These changes are described in detail below. While the core method remains intact, and some parameters are still directly comparable across all years, these changes must be taken into account when making comparisons of certain parameters using observational data obtained before 2020 and those obtained during and after 2020. All sampling stations have been selected in hard-bottom habitats using a stratified random sampling design, and the stations have been designed using the split-panel approach (combination of fixed and non-fixed transects).
  • Each sampling station is located using a GPS receiver. Upon reaching a given station, a small weight and line tied to a buoy is carefully lowered to the ocean floor. In optimal situations where four divers are available, two divers enter the water first to carry out the fish surveys. For permanent sampling stations marked with rebar, the divers descend to the weight tied to the buoy and locate the rebar representing the beginning of the transect. For non-permanent sampling stations the weight tied to the buoy is used to represent the beginning of the transect. A 30-meter transect is laid out [25 m-long transects were used prior to 2017] beginning at the rebar or weight. The transect is laid out in a clockwise direction relative to the island, following the depth contour if it can be readily determined; if the area is relatively flat and a depth contour is not readily discernible the transect is laid at an angle parallel to the reef margin (which is determined prior to entering the water). At permanent sampling stations the transect tape is deployed between the three rebar representing the beginning, middle, and end of the transect. Surveys are not completed if the visibility is less than 7.5 m. Compact digital point and shoot cameras and housings are used by individual observers to document unknown organisms, incidences of coral disease, and species/behaviors of special interest. To conduct the reef fish surveys divers are positioned at 7.5 m and 22.5 m along the transect and count fish within a 7.5 m radius cylinder extending from the substrate to the limits of vertical visibility. The simultaneous surveys start once the divers deploy the transect and both divers are ready to proceed. To minimize diver disruptions, the two divers conducting the benthic surveys enter the water approximately 20-30 minutes after the divers conducting the fish surveys, once the fish team has finished enumerating fish. In situations where only three divers are available, all three divers enter the water at the same time and remain as a three-person buddy team to ensure diver safety throughout the survey. A fish diver partners with a benthic diver when two fish divers are not available. In this situation, the fish diver lays the transect and conducts the first SPC at 22.5 m while the benthic diver works from 0-15 m; they then switch positions along the transect.
  • The SPC surveys are conducted in two parts. During the first five minutes, divers record all species observed within the cylinder, but do not count or size fish. All fish are identified to species level or the next lowest taxonomic level possible (genus or family). While some small and/or cryptic taxa, such as most gobies or blennies, are not given high priority in the survey and are usually not reported, some larger-bodied or otherwise notable representatives of those taxa, such as Exalias brevis, Plagiotremus spp., and Valenciennea strigata are typically reported. Small fishes and those cryptic during the day, such as apogonids and holocentrids, are explicitly targeted for the survey but are likely undercounted. If a rare fish (shark, species of concern, large mobile predators, etc.) is observed during the first 5 minutes, it is counted and sized, but the diver notes that it was not an instantaneous count. Note that this approach to surveying rare fish was not in place during surveys carried out at the Tumon Bay and East Agana Bay in 2010 and at the Western Shoals site in 2011. For surveys at these sites during that time period rare fish were counted and sized but it was not clear if it was an instantaneous count or not. After the first five minutes divers enumerate fish, one species grouping at a time, using rapid visual sweeps of the plot. The counts are designed to be instantaneous to avoid double counting. All fish of the target species within the SPC boundaries are counted and sized to the nearest centimeter; however, divers use size classes for large schools or high densities. Note that the list of species considered a target species for counting and sizing changed beginning in 2020 to include only food fishes (see process step below for more information). At the end of the survey, divers swim throughout the 7.5-m radius plot to enumerate small and cryptic species that were not captured from the stationary central position. The fish team conducts roving diver swims throughout the survey station after the SPCs to document species richness across the site. While core aspects of fish SPC survey, namely the listing of all species in the first 5 minutes and the instantaneous counting and sizing of targeted species after 5 minutes, have remained consistent since the first GLTMP surveys in 2010, significant modifications have been made to the original method in the intervening years. These modifications, which must be taken into account during any temporal analysis of these data, are detailed in the process step below.
  • Record of modifications to the fish SPC method Survey years 2010-2011: Only instantaneous observations were recorded during this period. Non-instantaneous observations, such as those made of species that were listed during the first 5 minutes but were no longer present in the cylinder during the counting and sizing phase of the survey, were not recorded. However, as noted above, it appears as though some rare or transient taxa observed during surveys conducted in 2010 at the Tumon and East Agana sites and in 2011 at the Western Shoals site may have been recorded even if those observations were not technically instantaneous observations. Survey years 2012-2014: Beginning in 2012 non-instantaneous observations were included in the survey. Non-instantaneous observations include observations of species that are listed during the first 5 minutes but which are no longer present in the cylinder during the counting and sizing phase of the survey. For these observations divers record their best estimate of the size and number of that species as observed during the listing phase. Species that entered the SPC cylinder after the first five minutes were noted on the species list for the site, but on occasion rare taxa were counted and sized and noted as non-instantaneous observations. Survey years 2015-2019: Beginning in 2015 an additional type of non-instantaneous observation was recorded in order to account for fishes that were not recorded during the listing phase but which entered the SPC cylinder during the counting and sizing phase. All surveyed taxa--not just rare taxa--were accounted for, and these non-instantaneous observations were delineated by the time period within which they entered the cylinder (e.g., 5-10 min, 10-15 min, 15+ min). However, a review of the data collected during this period found that the two observers represented in this dataset differed in how they denoted fish that entered the cylinder after 15 minutes, with one observer (VB) explicitly noting them as occurring in the cylinder after 15 minutes and the other (AH) noting them as PRESENCE observations and providing count and sizing information for each. Because PRESENCE observations can also include fish observed outside the cylinder, and occasionally counts and sizing information provided for rare or otherwise notable taxa that occurred outside the cylinder, unless fish observations were explicitly denoted as occurring in cylinder it should not be assumed that this was the case. Survey years 2020-present: Beginning in 2020 significant changes to the fish SPC survey methodology were implemented in an effort to significantly shorten survey times. The core survey structure was retained in order to maximize comparability to previous observations, but the decision was made to focus only on food fishes (and a small number of notable non-food fishes) during the counting and sizing phase, and to eliminate observations of fish that were not present during the listing phase (e.g., Non-instantaneous 5-10, Non-instantaneous 10-15, etc.). A list of all food and non-food species and how each species is surveyed (e.g., counts and sizes, counts only, presence/absence only) using this modified method will be made available with the raw data when acquired from NCEI or can be provided upon request.
  • Raw data include individual fish observation records with the corresponding methodological information and physical data that reflect the description of the site. Fish observation records include species identification, length (cm), and length-weight values. The physical/methodological data for all records includes the following: site, station, station type, observer, date (day, month, year), latitude (dd), longitude (dd), transect, cylinder radius (m), SPC replicate, observation type (instantaneous/non-instantaneous), depth (m), habitat, and wave exposure.
