32874 Reef Fish Surveys: CCR MHI Data Set Published / External 21559 Ecosystem Monitoring and Assessment Project Completed 2016 Surveys were conducted in the course of a reef fish survey cruise conducted by the NOAA Coral Reef Ecosystem Program (CREP) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). These data come from surveys conducted using close-circuit rebreathers. The use of rebreathers is intended to provide data that can be compared against data gathered on open-circuit SCUBA, which is the breathing apparatus typically used by CREP. The survey domain encompassed hard bottom habitats in the Main Hawaiian Islands and the stratification included island, reef zone, and depth. Sites were surveyed using the stationary point count (SPC) method to quantify reef fish assemblages. At each survey site, fish biologists entered the water and conducted paired fine-scale (~700 square meters) and high degree of taxonomic resolution Rapid Ecological Assessment (REA) survey to assess species diversity, size distribution, and abundance of fishes at the site. At each site, one survey was conducted on open-circuit SCUBA and one on closed circuit rebreather. Only rebreather survey data is described here. The goal of the project that these data were gathered for was to assess the effect of reducing the disturbance caused by divers on reef fish counts, at a range of locations varying from relatively heavily to relatively lightly fished areas. More specifically, it is understood that in locations with heavy fishing pressure, some fishes can associate the presence of divers with a risk of being targeted. There is therefore potential for diver presence to cause avoidance behavior which could lead to lowered fish counts and inaccurate estimates of differences between heavily-fished and lightly-fished locations. One of the main sources of disturbance caused by most SCUBA divers comes from the bubbles released by open circuit SCUBA equipment when divers exhale. Those bubbles produce both a visual and audible disturbance. Closed circuit rebreathers do not release bubbles during normal operations, and therefore use of rebreathers has the potential to reduce disturbance and possibly therefore reduce avoidance behavior, leading to more accurate counts in some locations. Because the Coral Reef Ecosystem Program (CREP) of NOAA's Pacific Islands Fisheries Science Center (PIFSC) uses fish surveys by divers on SCUBA to gather data that is used for a variety of management and research purposes---including the National Coral Reef Monitoring Program (NCRMP)---a series of studies were initiated to assess the importance of this issue - and these data are the rebreather component of those comparative surveys.

CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols. The following recommendations are for your consideration as you use this data: 1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators. 2) In all presentations, product releases, or publications using data generated by CREP, proper acknowledgement of both CREP and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below. 3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections. 4) Those receiving data are strongly urged to inform the CREP Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided.

However, all species identifications are made visually, sometimes in situations where a fish is only briefly seen. Only shallow water (0 to 30 meter depth range) hard-bottom habitats are surveyed. The survey sites were randomly selected using a systematic process based on available habitat and bathymetric data. Although efforts are made to include broad spatial coverage of surveys at each island, weather conditions and other environmental constraints may have prevented the team from surveying exposed reef areas. The same methods of data collection are used at each surveyed site, and periodic examination of the data is conducted throughout each mission to check for diver bias or other discrepancies. Observations, including species identification and sizing, are periodically checked during expeditions for consistency between divers. Data entry is usually conducted on the same day as the surveys using a data entry interface with several data controls employed, and are quality controlled by the divers using a two-person system. Following a mission, the data is then run through rigorous quality control checks by the data management team before the data are migrated to the Oracle database. Given the size of the data set, there remains some possibility of typographical or other errors. Yes Unknown Yes No Unknown NCEI-MD Unknown NOAA IRC and NOAA Fisheries ITS resources and assets.

At the start of a survey dive, a pair of divers first lay down a 30-m transect line along a predetermined depth contour, and then the two divers move to the 7.5- and 22.5-m marks on that line; these marks serve as the centers of two adjacent SPC cylinders. During the first 5 minutes of a survey, the divers create a list of the fish species observed in or passing through their cylinder. After the first 5 minutes, divers systematically proceed down their species lists, counting and estimating the size (total length, or TL) of each fish present to the nearest centimeter. Species seen after the 5 minutes or outside of the survey area are recorded as present. Person Ayotte, Paula M paula.ayotte@noaa.gov 1845 Wasp Blvd. Honolulu HI 96818 USA (808)725-5403 Ayotte, P., K.
